Internet Security Basics 101 by: Niall Roche

The explosive growth of the Internet has meant that thousands of people are today experiencing the joys of being online for the first time. With growth there always comes pain. Be it your growing pains as a child or the growth and development of this part of our culture called the Internet. Firstly we need to quickly explain what the Internet is and where it came from. The Internet is the offspring of a military project called Arpanet. Arpanet was designed to provide reliable communication during global nuclear war. A vast network of interconnected computers was set up all over the world to allow the various branches of US and NATO forces to communicate with each other. Nuclear war never came (thankfully) and the world was left with a massive network of computers all connected together with nothing to do. Colleges and universities started to use these computers for sharing research internationally. From there it grew and spread outside colleges to local homes and businesses. The World Wide Web was born and its father was a guy called Tim Berners Lee. When you're connected to the Internet you're sharing a vast network with hundreds of millions of other users. This shared network provides resources that 15 years ago were never thought possible. Unfortunately when something is shared its open to abuse. On the Internet this abuse comes from hackers and virus creators. Their sole intent is to cause chaos and/or harm to your computer system and millions of other computer systems all over the world. How do you combat this? You need an Internet security system. This might sound complicated but your Internet security system will be quite straigtforward being comprised of just 2 - 3 Internet security products. We'll look at each of these products in more detail now: AntiVirus Software The first and most critical element of your Internet security system is antivirus software. If you don't have up-to-date antivirus software on your PC you're asking for trouble. 300 new viruses appear each month and if you're not constantly protecting your system against this threat your computer will become infected with at least one virus - it's only a matter of time. Antivirus software scans your PC for signatures of a virus. A virus signature is the unique part of that virus. It can be a a file name, how the virus behaves or the size of the virus file itself. Good antivirus software will find viruses that haven't yet infected your PC and eliminate the ones that have. Antivirus software can only protect your computer from viruses trying to infect it via email, CD-Rom, floppy disk, Word documents or other types of computer files. Antivirus software alone will not keep your computer 100% safe. You also need to use firewall software. Firewall Software The use of firewall software by home computer users is a relatively new occurence. All Internet connections are a two way process. Data must be sent and received by your computer. This data is sent through something called ports. These are not physical things rather aspects of the way your computer communicates online. Firewall software watches these ports to make sure that only safe communication is happening between your computer and other computers online. If it sees something dangerous happening it blocks that port on your computer to make sure your computer stays safe from the person who is trying to hack into your system. An easier way to understand a firewall would be to picture your computer as an apartment complex. At the front door of this complex there is a security guard. Every person who enters the complex must pass this security guard. If the security guard recognizes the person entering as a resident he allows them to pass without saying anything. If, however, the person entering the complex is unknown to him then he will stop that person and ask for identification. If they have no business being at the apartment complex he escorts them from the building. If you are not currently using firewall software your computer will get hacked into - that's a guarantee. PopUP Blocker You can get a good popup blocker at no cost. An easy way to do this is to install either the Google or Yahoo toolbar. Both of these come with popup blockers built in. Popups are not necessarily dangerous but are a nuisance and using either of these toolbars will make your life that bit easier. A simple rule for practicing online security is: "If in doubt then don't". If you don't recognize the file, the email address, the website or if your gut feeling says "no" then don't click that button.

Computer Rental: Worth Your Money? by: Sandy Baker

Is computer rental worth the money? Depending on the type of computer that you have a need for as well as the expenses that you plan to save, computer rental may or may not be the right road for you to go down. One thing is quite certain. That is, there are a number of companies out there right now wanting to provide you with the computer rental that you are after. They offer a wide range of products and services. But, is it worth spending your money on these computer rentals? Or, maybe you should just outright make the purchase? The value of the computer rental is dependent on the need that you have as well as the overall need you expect to have down the road. It makes sense that if you only plan to use the computers for a few days or weeks that you should consider the computer rental industry. Often times it is important to have a large group of computers ready to go but you really have no need for them after a certain point. This happens and it just makes complete sense to use computer rental services. If you plan to rent a computer for a continuous time period, then it may just be well worth it to actually make the purchase. For example, many individuals find that computer rental is a low cost option to purchasing and owning a computer. For personal use, though, it makes very little sense as you will likely be able to find a PC at a much lower cost in the long run. Regardless of your need of computer rentals, it makes good sense to shop around for the right deal. And, it also makes sense to get the exact computer that you need as well as a back up service should you need that as well. Computer rental is something that many corporations need and therefore it is important for services out there to satisfy their customer’s demands. Computer rental services can be found throughout the web as well as in most local areas. About the author: For more information please see http://www.computer-rental-deals.co.uk

Computer Network Installation by: Adrian Griffiths

has become an essential prerequisite for any efficient modern-day business as it allows employees to truly work as a team by sharing information, accessing the same database and staying in touch constantly. For a computer network to give the best results, a lot of detailed planning and foresight is required before installation. Firstly, an organisation needs to clearly define its requirements – how many people would use the network, how many would use it locally (within the office) and how many might require remote access (from a different location), how many computers and other devices (servers, printers, scanners) would be connected to the network, what are the needs of the various departments and who would be in charge of running/managing the network. It also helps if one can anticipate the direction the company would take in the near future so potential growth can be factored in during computer network installation. The technology issues should also be ironed out in advance – hardware, software, servers, switches, back-up devices, cables and network operating systems. Make sure you have the required licenses to run the software on all your machines before installing a computer network. Alongside computer network installation should proceed the building of a dedicated technical support staff, either within your own organisation or outside consultants. Delegate responsibility clearly for network management. Before installing the network, you also need to choose the security mechanism to protect corporate data and keep viruses at bay. The transition to a new or upgraded computer network can bring some teething problems. To minimise chances of confusion, the company might need to train its staff to make them familiar with the new system. Careful planning will to a large extent prevent crises like system downtime and network crashes.

Computer Hardware Preventive Maintenance Software - by: Jennifer Bailey

Computers often break down at the worst of all times. These problems can be averted, or at least minimized with preventive maintenance. Several methods of keeping computer hardware in good working order deal with the external components of the computer, such as the keyboard and monitor. For example, it is important to keep the processor away from excess heat and moisture. There are also computer hardware preventive maintenance software programs that can help with the upkeep of other internal aspects of a computer. While it is rare to find a CMMS that works on all of a computer’s hardware, many different programs can be utilized simultaneously. Some computers have periodic automatic updates available that can be downloaded and used to improve the computer’s performance. Other software programs, known as disk defragmenters, manage hard drive space so that software programs take less time to access. Programs known as hardware diagnostic utilities can check the computer’s hardware components and alert the user about any potential failures. Since some new hardware will not always work on all computers and could cause existing hardware to malfunction, it is important to have a CMMS program to ensure that the new hardware is compatible with existing hardware. Antivirus programs are another important component of computer hardware preventive maintenance software. Computer viruses have become increasingly common in recent years and can render a good computer useless. While computer viruses mainly attack software programs, they can ruin hardware as well. Several manufacturers make reliable antivirus software. A couple of well-known companies are Norton and McAfee. As with much preventive maintenance software, these programs are usually available for a free trial period before the user must pay a subscription fee. Computer hardware preventive maintenance software is necessary to keep computers in good working order. This software manages aspects of computer hardware that would be difficult and time-consuming for even the most computer savvy users. About the author: Preventive Maintenance Software Info features detailed information on preventive maintenance software for health care and correctional institutions, computer hardware, and personal assets, as well as reviews of preventive maintenance software companies. Preventive Maintenance Software Info is the sister site of Fleet Maintenance Software Web.

Computer Components for Idiots by: Ron King

There are many fancy add-ons for computers, but the basic components of the computer are simple and universal. If 1 of these main components is missing, it’s not a computer. The 4 essentials of every computer system are: a motherboard, a Central Processing Unit (CPU), memory, and a hard drive. These components are installed in a case to which are attached a monitor, a keyboard and a mouse. That’s your basic computer. Mother WHAT? The motherboard ("mobo" for short) is the foundation. Everything attaches to the mobo -- the CPU, memory, hard drive, monitor, mouse, keyboard, add-on cards, even additional peripherals like printers, scanners, and speakers. The motherboard is like the nervous system and skeleton of the human body -- it provides support for the internal components and also passes information between the computer parts. CPU If the motherboard is the nervous system, then the CPU is the brain. Most of the mathematical manipulations that make computers operate are done by the CPU. Other components may also have their own processors, but their results still have to be passed through the CPU. The speed of the computer is usually measured by the speed of the CPU. Even though other factors also affect overall speed, the CPU rating is generally seen as the single most important measure of performance. Modern CPUs are usually rated between 2.0 GHz and 3.0 GHz, although each passing month will see increasing performance. This measurement refer to the number of calculations the processor can make in 1 second. The higher the number, the faster (better) the computer. CPUs generate a lot of heat doing this work, so they need a heat sink and fan to keep them from overheating. Heat is a major enemy of the computer and directly affects its life span. Computer Memory RAM (Random Access Memory) is the part of the computer that stores information the computer needs while it is operating. It is Random Access because the computer can get the data in any order, not necessarily the order in which it is stored. Generally speaking, the more RAM the better. 512 to 1024 megabytes is common for memory. The most common type of RAM these days is DDR-SDRAM, which stands for double-data-rate synchronous dynamic random access memory. We already know what the RAM part means. DDR means that the data is accessed twice as fast as ordinary RAM. The latest type of RAM is DDR2. It offers even faster access rates and is quickly becoming the standard for computer memory. Hard Drive All the data contained in RAM is lost when the computer is turned off, so there has to be a place to store it permanently. This is what the hard disk is for. It holds the computer’s operating system. An operating system like Windows uses around 4 gigabytes of hard drive space. The extra space is used to install computer programs and to store your personal data. 80 gigabyte hard drives are common, but 400 GB units are available. Furthermore, you can install more than 1 in a computer case for added security and convenience. Peripherals All you need to complete the basic computer system is a monitor, keyboard and mouse. Accessories like a printer or scanner are useful for office work, and gamers will probably want to add speakers and joystick controls. So there you have it. The basic computer needs just 7 major components. For the best performance, these components must integrate well. The motherboard is the most important component for determining the type and specification of the other parts. Choosing an appropriate mobo for your computer needs is the first step and may require a quick call to your local geek. Soon YOU will be considered the local geek!
