Do You Need an Operating System?

Peripherals and system parts are a collection of electronics that work together in order to perform a specific task. The program that every computer uses to control and manage all these parts is called the operating system (OS).

For example, a user that wants to write a document and print it out on a network printer needs an application like Microsoft Word to accomplish this job. Microsoft Word works with the OS in order to accomplish all the word processing tasks. The operating system controls all the input and output functions. All the personal computers, the servers and the handheld devices require an OS in order to function.

The operating system works like an interpreter between software applications and the hardware. An individual interacts with the computer hardware through an application, like Microsoft Excel, Adobe Photoshop, etc. Software applications are made for a particular purpose. On the other hand the OS is responsible for the communication between the software application and the computer's hardware.

When a PC is powered on it loads the operating system from the hard disk into RAM. The part of the operating system that interacts directly with the hardware is called kernel. The part of the operating system that it is visible to the user is called shell. The user can use the shell from the command line interface (CLI) or from the graphical user interface (GUI).

The user that uses the CLI interacts directly with the OS in a text-based environment by typing commands at a command prompt. The computer executes the command and provides textual output. The user can also use the GUI and control the computer from an environment that uses graphical images, multimedia, as well as text. This is more user-friendly and requires less knowledge than CLI. Therefore, most users work with GUI environments. Microsoft Windows and Linux operating systems offer both GUI and CLI.

All the modern operating systems allow the user to multitask. The OS keeps track of which resources are used by which software program.

In order to work with devices that are not directly attached to the PC, a special software application must be installed that allows a device to send and receive data from the net. This is called redirector and usually it is an integral part of the OS but sometimes you need to install it separately as a network client. After you install it, the OS becomes a network OS (NOS).

How 3D Printing Brings Value?

How can 3D model printing serve you? Well that depends on who you are. Are you an engineer or 3D artist? Are you a consumer? Are you in a product development business? Do you like custom goods? 3D model printing isn't for everyone, but it has the potential to change the world. Let's go over what 3D printing is first.

3D printing a style of additive manufacturing in which a three dimensional object is created by laying down layers on top of layers in which these layers are made out of certain materials. Each of these layers are bonded together within a 3D printing machine. These machines produce 3D objects with great precision, and can form almost any object out of a wide variety of materials. The materials used may consist of plastics, metals, ceramics, or even precious metals. The use of these machines can produce products at a much faster rate than traditional additive manufacturing technologies. Basically, 3D printing consists of layer by layer assembly of objects within a 3D printer. The basis for each product comes from a 3D design, which would be created by an engineer or 3D artist. This technology allows for 3D model printing to be completed by anyone with Computer Generated Image (CGI) experience.

As artists and engineers design each model, the sky is the limit! Artists can design virtually anything to be printed. The limit is purely each designer's imagination. What does this mean? Truly custom products can be designed for consumers. There will be a massive avenue for custom manufacturing! If you think that engraving items is special, just wait until 3D model printing becomes much more widespread. The design of someone's face could be possible! Imagine how creative a valentines gift or Christmas gift could become.

There is also another aspect of 3D model printing - the business side. Perhaps a company is among a phone company, more specifically, the hardware for cell phones, not service. If a new phone were to be launched, wouldn't it be a great idea for product developers to 3D model print a design of a phone, and give it to investors to where they could HOLD the design? That might be much more reliable rather than seeing a digital picture of the phone, and creating a hold-able product might influence the decision of investors.

In addition, let's look at the engineering aspect of 3D model printing. How could this change the game for certain businesses? Let me cover an oil and gas company. An oil well is about to be drilled, and a highly specific valve system needs to be created. The engineers need this ONE highly specific part to be designed, but they don't want to have to deal with paying for the production of 50 of them. At the same tile, they would like it in a very specific material without being gauged for pricing. 3D printing could save the day by allowing for the creation of only 1-3 pieces, at a much more inexpensive price.

How About Computer and Keyboard Recycling?

Everybody knows it is a good thing to do to recycle. If you recycle you are preserving the earth and re-using materials instead of throwing them into a landfill due to laziness or ignorance. Did you know that there are special companies that are made for recycling electronic items specifically?

The most commonly recycled electronic items of all are computers and their keyboards. Just with one item, you can contribute greatly to making the earth a better place to live. There are so many different metals and plastics involved in making electronic items that are harmful to the environment and by taking them out of the picture we can actually reverse the earth's destruction rather than help it move forward.

Recycling your keyboard and computer is easy. All you have to do is call a recycling company near you that takes electronic items and you just give them a time and a place to come pick it up. You can also drop it off if you don't want to have them come pick it up but it is just an easy solution for you so you have no obligations.

When they take your items they will separate them into all different categories according to material. The plastics, each different type of metal, glass and other information holding pieces will be disposed of separately.

If you are holding on to an old computer because you are afraid of the information getting out, you need not worry about that at all. All electronic recycling places take an oath to never tamper with hard drives or other pieces of equipment that hold confidential information. They will tell you about their exclusivity and privacy policies which will allow you to feel relaxed while letting them handle your belongings.

They will take your information and securely dispose of it properly. This means after they pick it up from you, they will give you a tracking number. You will be able to see where your item is at all times and they will even notify you when it is destroyed. It is guaranteed to be destroyed within 48 hours of pick up. This means all informational pieces get thrown into a shredder and are made sure to be irretrievable or even recognizable for that matter.

My New Operating System

Nowadays you can find several different OS available. The most well-known are the following:

Microsoft: Windows Vista, Windows 7, Windows 2008 Server, UNIX-Based: IBM AIX, Hewlett Packard HPUX, and Sun Solaris, Linux-Based: Ubuntu, Fedora, Macintosh OS X.

While all the above OS require a commercial license, there are more than a few OS released under a different kind of licensing arrangement. This is called GNU Public License (GPL).

Commercial licenses typically prohibit users to modify the software in any way. Windows 7, Mac OS X and UNIX are commercial operating systems.

On the other hand, the GNU Public License (GPL) permits users to modify and improve the program, if they want, to better suit their needs. The most common operating systems that use the GLP model are Linux and BSD.

All the operating systems need a specific amount of hardware resources. For example they have minimum RAM requirements, minimum available hard disk space requirements, minimum processor requirements, etc.

Companies usually state both a minimum and recommended level of hardware components. When you install the minimum defined hardware configuration, the computers' performance is frequently poor and cannot support any additional programs. The recommended hardware is always the best option. If you purchase the recommended hardware you will be able to support standard as well as additional applications and resources.

Almost all the OS developers test several hardware components and verify that they are compatible with the OS. Before purchasing and installing a new peripheral or hardware module always confirm that it is certified to work with your operating system.

Picking an appropriate operating system requires numerous features to be considered before making a final decision.

First, you have to make sure that the OS being considered supports totally the requirements of the user. Verify for example if the OS supports the future programs. After that, check if the available hardware resources are sufficient to support the new operating system. For instance check the RAM, the CPU, and the available hard disk space.

Another very important factor that you have to consider is the total cost of ownership (TCO). This is something that can really change your final decision. This not only includes the costs of purchasing and installing the operating system, but also the support costs.

How to Win in Battle Against Military Robots?

Advanced military weapons have always scared human beings, and rightfully so because humans inherently wish to stay alive. They fear the enemy might come into their city, or civilization and wreak havoc. In fact this is a real fear because throughout human history there have been battles, wars, and marauding armies raping and pillaging. Okay so, I'd like to talk about a new paradigm of warfare with regards to advanced weapon systems, namely I'd like to discuss the inherent fear of autonomous robotic military equipment.

Why is it that humans fear robotic weapons systems so much? Is it because of the unknown, or a misunderstanding about what these systems are about, or how they work? Perhaps from an American perspective it is good this fear exists in the minds of the enemy as we use our UAVs or unmanned aerial vehicles overhead. Still, we do have some fear amongst our own citizens, and perhaps this has to do with famous science fiction movies such as the Terminator series, but is this justified? And how can you win a battle against military robots?

Understand the Sensors Used by Robotics

First, I would submit to you that you need to understand how they work, and how they collect their information to do what they do. They use sensors, and the sensors do not work like human eyes, nose, ears, feel, or hearing. Now then they may have 4 or 5 Sensors which to take in information in this regard, but they do not work the same as human senses. Thus, you may very well be able to fool the Sensors. Once you fool the sensors the military robotics are not as accurate, and therefore cannot do the job intended.

Hide in Broad Day Light

This also allows someone to hide in broad daylight. For instance consider that the sensors might be based on a heat signature, but if the ambient temperature is close to the same temperature as a human being, then all the suddenly the human being blends into the background. Yes, if the sensors are really good they will still be able to pick up a human, but there are other ways besides infrared which are used by these robots, and if you can disable the sensors, they cannot sense you.

Hack the Enemy - Use the Machines Against Them

There are indeed ways of interfering with the Sensors, and the robotic systems, or even using cyber warfare techniques and hacking to turn those very robots against their makers. In other words hijack the enemy's robots to serve your will and achieve victory in battle. It can be done. Indeed I hope you will please consider all this and think on it.

IPTV For Your Home Or Office

If you are looking for a type of Television entertainment that can provide you with excellent facilities and a straightforward set up, an IPTV service is the ideal solution. This is a service that enables you to view Television online, as an alternative to depending on the traditional types of transmission such as fiber and satellite systems. This means that this kind of Television has some added benefits that one can take advantage of.

For starters, the quality of this type of entertainment is far better than other forms. Since there's usually very little interference when signals are being transmitted online, one rarely suffers from low quality such as whenever you watch satellite Television and there's cloud cover. The results is that one can always enjoy high quality, as long as your internet connection is reliabe.

In addition to that, you are able to also benefit from a chance to rewind live Television. This has been made possible by the fact that when streaming, the data is generally buffered in your computer for better quality. This means that whenever you miss a programme, you are able to simply rewind the show to that point where you want, and then simply start viewing whatever you had missed.

In a lot of cases it is more economical to watch Television online as opposed to pay for satellite or Cable. An important reason for this is that the equipment required to broadcast signals online is generally much cheaper than that needed to perform the same function over other media. This means that if you are on a spending budget, this is a excellent solution.

When you need to subscribe to such a service, there are a number of things you need to consider. Initial of all, you really need to make sure that your internet connection is trustworthy. Since the signals will be transmitted online, any suspect internet connection may affect the quality of your viewing. It can end up being better to have a high speed internet connection for this sort of use, as streaming online TV can be very data intensive. It's also advisable that you also have an unlimited data plan for the same reason.

Computer Network Solutions for Small Plus Medium Business

our company is increasing. As well as all employees are difficult about the increasing complexity of sharing files. Your statement database is on a computer which container simply be accessed by your managerial assistant, plus you are anxious concerning not having a central backup of the files life form saved on each workers computer. If this every one sounds recognizable, it might be time to realize a computer system. In this conversation, we'll appear major processor network solutions for little as well as medium businesses.

Networks start at what time two or additional computers are linked so that information can be shared. In arrange to attach to some type of network; a computer requires a system certificate plus CAT6 wire. If the computer has a wireless system card, broadcasting signals can be used in position of the cables. A network too requires an element of equipment called a control, which acts as a middle direction-finding center for the information life form collective. A button is type of similar to a mail room in a big corporation. It makes certain the addressed messages obtain to the correct receiver.

An additional ordinary type of network is called a client server network. This kind of network uses a middle server plus particular network software. The server is devoted as well as is merely used to store files plus run server tasks. The computers which attach to the server are identifying clients plus these are the equipment the corporation employees would use. The server acts as the "hub" of the network, as well as does the majority of the "after the scenes" preservation plus storage. Ordinary server network working systems comprise Windows Server or else Linux operating system.

Operating System Options and Installation Methods

An OS is installed on the computers' hard disk, inside an area called hard disk partition. There are several ways for installing a new operating system. The installation method is based on the system hardware and end-user requirements. Generally, you have four basic options for the installation of a new operating system:

Clean Installation

We can perform a clean installation on a new computer or in those cases where there is no upgrade path between the current operating system and the new one. This type of installation deletes all data on the hard disks partition where the current operating system is installed. A new PC requires, of course a clean installation. You can also do a clean install when the current operating system installation has corrupted files or does not work properly.

Upgrade Installation

Sometimes, it is also possible to perform an upgrade. When you perform an upgrade, OS configuration settings, installed programs and data are preserved. With this installation you have nothing to worry about, because you will not lose any personal data. You will just replace the old operating system files with the new, upgraded files. However, keep in mind that after the upgrade the applications and drivers that are incompatible with the new OS will not work as expected.

Multi-boot Installation

Another option is to install multiple operating systems on a single computer. You can install each OS inside a different disk partition and this way every OS will have its own files and configuration settings. On multi-boot installations, the users see a menu when they open their computers and they have to select the desired OS. Of course, only one operating system can run at a time.

Virtualization

This is relative new technique that is often used on servers. With virtualization we can run numerous copies of an operating system on a single set of hardware and create this way several virtual machines. Every single virtual machine works like a separate computer. This technology makes a single physical hardware resource to appear like multiple logical resources.

Before starting any operating system installation you have to make sure that all the hardware is certified to work with the new operating system. Also confirm that the hardware resources meet the minimum installation requirements. Moreover, when you perform an upgrade it is a very good practice to perform a virus scan before starting the installation and a complete full backup of all your personal data.

How About Information Assurance - The Availability Attribute

Information Assurance assigns systems to shield data and the computer systems they reside on, and the transmission approaches processed to transmit the data. Availability is certified by requiring an impeccable and prompt avenue to information services and information only for entrusted users. By achieving consistency of the material and data structures of the operating system, hardware, software and filed material and analytical accuracy, entirety and dependability, integrity is guaranteed. Integrity can also assure against unauthorized deletion of information. Information assurance also certifies acceptance by guaranteeing the certainty of a communication or a document and its producer, and also by substantiating an individual's approval to accept explicit data from the architecture. Confidentiality is preserved by only exposing information to trusted organizations or systems. Non-repudiation is included, which is ensuring evidence of delivery to the transmitter of material and supporting validation of identity to the receiver, to require neither recipient can afterwards debate having processed the data. Information Assurance also accounts for additional fundamentals to include reconstruction of information systems by assembling protection, detection, and reaction qualifications.

Information Assurance furnishes availability by furnishing up-to-date and impeccable access to information and information services for entrusted users. The users need have reliable avenue to all hardware, software, services and information. Often availability is also assessed in terms of what is attainable to just mission-critical processes, but it need also be evaluated for the comprehensive system.

Design theories that promote availability can be incorporated into the system. Elements and subsystems need be able to be gracefully restarted at will. Subsystems and elements have to be independent of each other and adhere to an open architecture. Subordinately critical missions or functions should be uncoupled from more crucial ones, as well as more risky functions from those that are less risky. Networks, processes, and information assembly can also be optimized for mission availability. The architecture can be securely executed for increased availability so that platforms, software and architecture are produced as services such as cloud computing. Cloud computing can support additional availability owing to proficient usage of assets and making individual disruptions imperceptible to the user. The redundance of services like these make the architecture more tolerable of failures and unavailabilities.

Timeliness, connected to Quality of Service (QoS), is notable since belated might be equally as bad as not at all. Resource allotment could be changed to adhere to timeliness requirements. There are repeatedly tradeoffs between QoS attributes and Information Assurance specifications.

Understanding How Data Packets Travel Across the Network

When troubleshooting IP networks over Ethernet it helps to understand how packets travel across the network. Packets use two different mechanisms to get from point A to Point B, or from the source to the destination. IP addresses and MAC addresses.

The MAC address is the layer 2 address that represents the specific hardware that is connected to the wire. The IP address is the layer 3 address that represents the logical identity of the device on the network.

MAC Address

Most every computer today has some sort of network interface card (NIC) either built-in or installed on the computer. Every NIC is created with a hardware number permanently "burned" into it. This permanent hardware number is known as the MAC (Media Access Control). MAC addresses are 48 bits in length and are usually displayed as a 12 digit hexadecimal number.

MM:MM:MM:HH:HH:HH

The first 24 bits (or 6 digits) represent the manufacturer of the NIC. The last 24 bits (6 digits) are a unique identifier that represents the Host or the card itself. No two MAC identifiers are alike.

IP Address

The IP address is the logical address that is associated with the MAC for a particular device. IP addresses (IPv4) are a 32 bit (12 digit) number representing 4 binary octets.

Both an IP and a MAC are needed for data to travel across an Ethernet network.

The ARP Protocol

When a computer sends data over the network, it first needs to find which route it must take. Will the packet stay on the network or does it need to leave the network. The computer first determines this by comparing the subnet mask to the destination ip address.

Once this destination is known, Address Resolution Protocol (ARP) is used to find the next hop on the network. ARP's job is to basically discover and associate IP addresses to the physical MAC.

For a packet that has a destination on another network, ARP is used to find the MAC of the gateway router. An ARP packet is sent to the gateway router asking for it's MAC. The router reply's back to the computer with it's mac address. The computer will then forward the packet directly to the mac address of the gateway router.

When the gateway router receives the packet it will remove it's mac address as the destination and replace it with the mac address of the next hop router. It will also replace the source computer's mac address with it's own mac address. This happens at each route along the way until the packet reaches it's destination.

Going Postal - An Example

Let's use the postal service to help explain this. Think of this process like taking a letter and stuffing it in an envelope. Then take that envelope and stuff it in another envelope addressed to the local post office. The post office then takes out the inner envelope, to determine the next stop on the way, puts it in another envelope with the new destination.

Way Find The Best Wireless Router Deals

Finding the best wireless router deals is not a simple matter of driving down to the local electronics store and picking up whatever is on sale. There are many things to consider and you don't want to make a hasty choice that you may regret later. Most people don't want to get into the details of making this decision because sorting through all the different wireless routers and their various features can be like trying to learn a new language.

In this article I'm going to show you an easy way to choose which wireless router is best for you and provide a resource that makes the process even easier. There are two things you need to take into consideration when shopping for the best wireless router deals.

They are:

1. What type of network user are you? Are you a Surfer? A Streamer? Or a Gamer? (More on these below.)

2. Future proofing. Sure any cheap run-of-the-mill router may do fine for just a computer or two and maybe a printer, but if you think there's a remote possibility you'll be adding more wireless devices to your network in the near future you'll probably need to upgrade sooner rather than later. When you look at it from this perspective you are actually saving money by getting a good wireless router to start off with instead of being forced to upgrade every time you buy new wireless devices.

Types of Network Users

I like to break these down into three groups: Surfers, Streamers and Gamers.

Surfers

Surfers are satisfied with checking their emails, shopping online, printing out documents and maybe downloading the occasional music or movie file. Network users like this don't spend a lot of time on their computer and only use it when they have to. Any run-of-the-mill Wireless N router is fine for Surfers because they don't put much load on a wireless network and probably never will.

Streamers

These are your movie and music lovers. They love to find large files online, download them to a central computer or media server, and then stream them out to all the other computers on their network. This requires a wireless router that has additional memory and processor power. A built-in USB drive port for sharing out files is also a good idea.

Gamers

Gamers usually put the same amount of demand on a wireless network as Streamers do, but with an important difference. Surfers and Streamers can ruin a wireless network for Gamers who, in turn, can make living in the same household miserable for everyone else. The slightest drop in connection won't really bother a surfer, but the same drop in connection is a cataclysmic event for a Gamer. Hours of progress spent on a role-playing game can be lost in a few seconds or the main character in a 1st person shooter can suddenly become an easy target.

Tech Jobs and Cloud Computing

Being able to access information from your home, office, school, etc. is something that is becoming more and more of a reality. It's a result of cloud computing. This innovation makes it possible for people to access whatever is important them without being tied to their computer. So, if you want to share a document, photo, video, or even music clips with friends and family, you can do so no matter where you are.

If you are trying to make a decision on a future career choice, becoming proficient in the cloud-computing field can make your search for tech jobs even easier. That's because there aren't many people that can say they have extensive experience with this quickly emerging industrial science. Careers of the past, such as help desk technician are quickly fading. Many people are familiar with computers, the Internet, social media, and more, and the need for someone to walk you through computer basics is becoming obsolete.

People want information quickly and almost immediately. Deciding to pursue tech jobs in cloud computing can set you on a path to a bright future. More and more companies will be requesting individuals that can manage cloud projects. The good thing is that many industrial science experts already possess some of the skills needed in order to work well in the cloud-computing field. Some of these skills involve making sure business systems are set up with secure information systems, data integrity, proper networking and more. In addition, the right candidate will understand the importance of aligning business and information technology to ensure things run smoothly.

Also, when pursuing tech jobs in the cloud-computing field, a company's needs can vary greatly. This means, some businesses may look for someone that has worked as a system's analyst and also knows coding. Or, on the other hand, another company may be in need of a technical writer that can help get the process down step by step because it doesn't matter how great the idea is if it can't be implemented properly.

Training Support Services for Optimal Course Design

In corporate training every learning programme has varying goals, objectives, strategies, budgets and audiences and therefore training preparation and delivery is critical. Conducting a Training Needs Analysis (TNA) is vital to developing, designing and delivering a course to meet your specific needs. While instructional design and learning theory is important for training course development, experience usually adds a key factor to develop best practice. A specialised blend of training expertise and learning technology is required to provide the most cost effective support service.

The good news is that you are not alone and expert Training Support Services can be engaged to assist you in developing a training solution that will be most appropriate for your environment. Using these services can prevent you from designing courses that are seemingly wonderful but nobody takes them or has fascinating content that teaches your audience nothing new or relevant. The underlying business goal in all training courses is to increase revenue and /or reduce costs. The greater the expected revenue the more budget can be set aside to fund the learning programme development.

Well-developed training programmes can assist organisations with productivity, job satisfaction, retention rates, error rates and customer satisfaction. Measuring the impact and effectiveness of a training programme is critical and metrics should be decided on when a course is designed so that they can be gauged before, after and for an extended period after the training has taken place. Participant feedback is also an integral part of the process as 'softer' elements such as cultural dynamics, values and best-fit for an organisation can be elicited from their responses.

When designing training programmes for adult learners an important point to consider during planning is that they come with a wide range of experiences, knowledge, interests, skills and competencies and this diversity must be accommodated. Adults prefer courses with 'real-world' applications where the training relates to their daily activities and teaches them relevant skills to develop in their environments. Knowledge transfer must be facilitated in the training process and learner interaction and coaching as well as other follow-up support processes is important for sustained learning.

Ways To Protect Your Data Online And Offline

The online world grows stronger and stronger with each passing year. Keeping your data safe both online and offline requires vigilance. Just as there are always improvements being made to enhance the way people do business online, there are people knowledgeable enough to abuse that technology for purposes of identity theft and other forms of cyber terrorism. If you really want to make the online experience the best that it can be now and in the long term, then you need to consider the following best ways to protect data, both online and off.

1) Encryption technologies

Your hosting provider and software that you use to build and develop your website should work in agreement with one another to stay on top of the latest in encryption technologies. You don't want your users to suffer as a result, so make sure that it doesn't affect usability, but at the same time be vigilant about what you have in place to protect you from harm.

2) Content control

Certain documents and writings should not be released to the public, so make sure that you have set content control standards in place that limit access to only the things you wish for the public to see. As far as other content is concerned, make sure that you trust the people, who are representing you, and keep vital things close to the vest at all times.

3) Personal information

Never ever ever share personal information across non-secure locations. Social security numbers, passwords, and other pertinent financial information should be off limits. You may even wish to partner with an outside firm that specializes in protecting personal data, just to ensure some kind of security with regards to your insurance.

4) Accessibility

Passwords remain one of the strongest things that you can have in the fight against online crooks. But you've got to be smart about how you use them to be effective. It is recommended that you use a different password for all of your important emails and accounts, and that you store these passwords in a notebook instead of the desktop on your computer. Cyber thieves are way too advanced in how they are able to break on to computers and make them available for their own personal use. You may even be sharing your hard drive with a thief and not know it. So if it has any direct or indirect tie to your reputation or finances, then you should probably forgo sharing it or storing it on modern technological devices.

Know More About Your Managed IT Services Provider

One thing you have to know about IT is that it is never stagnant. Everyday, new discoveries are being made and new technology are introduced. And to make room for these new technologies, companies must be able to adjust by accommodating all the changes that these new technologies require. Normally, this would be hard for a company who employs hundreds of people to do. However, with the help of a managed IT services provider, adjustments are not only easy but also refreshing.

Part of the responsibilities of a managed IT services provider is to make sure that a company adjusts to a new technology with ease. They do so by developing IT strategies that will suit the business type and business model of their clients. This, in theory is difficult considering there are so many types of businesses and business models employed in the market. However, this is where the true strength of IT service companies lie. They employ not just IT experts but also business authorities that help them analyze their clients businesses.

That being the case, these managed IT services providers are able to deliver high quality equipments, services and software programs that enhance the capabilities of their clients' businesses to produce high quality outputs without the high cost of production.

Aside from making sure businesses are always up to date with the current technology in the market, these IT service providers also take charge of very important system tasks: scheduled network and system checks, data back up, information retrieval, patch management and troubleshooting.

Through the routine network and system checks that they perform, they are able to discover potential issues that you might encounter and provide IT solutions that will prevent these issues from surfacing. These will also help them analyze how your system and network security is faring against web attacks. Should they encounter loopholes and exploits that web attacks can gain access to, they can easily reinforce your security without hampering your company's activities.

The routine data back ups are done to ensure that you will never have to lose important data anymore. It also guarantees that if your systems encounter issues that will prevent it from functioning well, you will never experience down times since your system's back up can easily be restored. Instead of having to wait days for your system to be up and running, you only have to wait for a few minutes or a few hours for your system to function normally again.

Three Good Reasons Not To Ban P2P File Sharing In Your Business

Any business owner who has experienced having their network crippled by having unwanted intruders brought on by Peer-to-peer (P2P) file sharing will want to ban their its use from their network. It's only natural to protect your resources from any and all threats that hamper productivity and cost money. But what if protecting your resources means that you are ignoring some key benefits to your business?

P2P file sharing has some great business advantages:

    Get information farther quicker - The idea behind peer-to-peer file sharing is sharing information. With the right infrastructure in place, businesses can interact with partners and vendors around the world regardless of time differences. Imagine working late needing specs for a presentation and realizing that the Rome office had an older version while the Cadiz office had the latest changes. Despite the time difference between each of these locations, having access to these files whenever you need them contributes to increased productivity and a healthy bottom line.

    More demands equal more capacity - Any server that experiences more demand is prone to bottlenecking, which means that higher demands for information mean slower network. With P2P file sharing, the more demand on the system, the more peers are present the higher the total system capacity. The original content distributor does not have to worry about adding more memory or getting a bigger server because there is more demand

    Reduce the risk of network crash - Network crashes are paralyzing to say the least. The worst part is when the network crash is fixed, the paralysis changes to frustration as the network slowly crawls. With P2P file sharing the whole network doesn't crash just because one computer crashes. If one peer on the network malfunctions, there are other peers from which you can get information. P2P file sharing systems have built in redundancy which makes them more reliable in the event of a crash.

In order for these advantages to be felt, businesses need to have proper controls in place

If you choose to allow staff to gain access to the cloud using their personal devices, create policies surrounding these devices. Require password access and train employees to respect security protocols.

Five Tips to Improving Database and Query Performance

Considerable amounts of planning needs to go into building a database application. There are a number of things which can affect performance in a negative way if best practices are not followed.

Performance might seem perfectly fine in a test environment with only a few thousand rows inside the database but when the application goes live and begins to grow the database, bad design considerations can become obvious very quickly.

When designing the database and building the code to query it, there are simple design considerations and best practices which can help ensure that as the database grows, the system remains responsive.

The following five tips are in no particular order of preference.

1/ Design tables with the appropriate indexes

The lack of appropriate indexes can lead to massive decreases in performance. As the tables become larger, the optimizer has to scan through the data to retrieve the required rows based on the WHERE clause in the query. Imagine using a phone directory without an index to tell you where the page was for your local plumber. It is going to be slower finding them without the page that tells you that they are on page 302 or your 500 page directory. The query optimizer has the same problem if indexes are not put in.

2/ Don't use SELECT * FROM

It is easy to write SELECT * FROM. Writing queries in this way is much quicker than writing out the required fields from the table. Well you reap what you sow. If you take the time to build that SQL statement properly, your return on investment will be improved response times. This is because the sql query is pulling back less data than if all columns were included. If you only need 3 columns and not the 10 that comprise your table then just select those three.

3/ Ensure that stored procedures are used

There are many benefits to using stored procedures. One of the benefits is that the optimizer can call upon a cached execution plan. Ad-hoc SQL requires more time and resource to execute because the optimizer has to work out the best execution plan to execute the query.

4/ Don't use cursors

There is a time for using cursors however they should generally be avoided unless absolutely necessary. The optimizer works best dealing with sets of data. It is not too great at doing things very quickly using a row by row method.

5/ Ensure that you have a maintenance plans in place

In SQL Server, you can build maintenance plans to help rebuild indexes and refresh statistics. In MySQL, this can be done using OPTIMIZE TABLE commands as part of a batch process. Ensuring that maintenance plans are in place helps to control index fragmentation. Up to date statistics helps to ensure that the optimizer can use the best execution plan for the query.

Convert Audio And Video Into Text With Digital Transcription

Digital transcription is the process of transcribing your audio or video files into written text using digital software. Previously, transcription was strictly a manual process wherein an individual would listen to your audio or watch your video file and physically write down the words they heard. However, this took a lot of time and was prone to human error. When it comes to audio and video transcription you want your text to be error-free, and it is vital that your text is clear, concise and extremely accurate. This is why digital transcription has become popular. Digital transcription is done by digital software, thereby making the entire process more accurate, quicker, and cheaper. Because the process is done with the help of software, you no longer have to pay the high prices you previously used to.

There are myriad benefits to transcribing. Video transcription helps the viewer follow the content of your video by enabling them to read the text. This is exceptionally useful in educational and business videos. Very often we are so distracted by the happenings in a video that we fail to pay attention to everything that is being said. By being able to hear as well as read whatever is there, you reinforce your point to the viewer. Audio transcription is essential as understanding something only by listening is very difficult. Keeping in mind that accents can be difficult to understand, and that people have a tougher time focusing without visual aid, it is easy to see the importance of audio transcription.

There are various digital transcription services that provide clear, accurate and error free transcription. More and more organizations are beginning to make use of their services, as the advantages of digital transcription are getting clearer. These advantages are easiest to see online where Search Engine Optimization requires text. Search engines cannot watch your videos or listen to audio files in order to decipher what your website is about. Very often this means that your website remains low in search results even though you may have all the relevant content. How do you change this? Digital transcription is a great starting point. Search engines understand and index text, and they use this to understand your website (mainly keywords linked to website content). In order to optimize your website, simply have your audio and video transcribed and see a tremendous boost in your Internet marketing and SEO campaigns.
