Why I’m not going to choose a Windows OS for my next computer. So alright I am not a computer geek nor am I a computer nerd. But I dislike being considered an intellectually negligible specimen with the IQ of room temperature by all those Uber geeks who have planned and executed the Windows operating system for my delectation. Now, I have been using the Windows operating system since 1999, but it is time for me to call a halt and check out some other operating system like Mac. Let me give you the reasons for this disenchantment. First of all, any operating system, which is not capable of asking me my serial number while loading into my computer, which makes certain that it is going to give me a signal that Windows has to be activated in one month, is not the operating system for me. So, all right, I spend oodles of dollars and buy the original Window operating software. After it has been reloaded up on my computer, I am asked to activate it now. By telephone. The telephone numbers do not work at all. They have never worked at all , they will never work at all. If that is not enough to make you breathe out fire and brimstone, (by the way I’m writing from India, and the toll-free numbers given are zonked completely.) After all, I have had a month trying to activate my Windows serial number by telephone. Then I decide to follow the next option, which is to activate the serial number online. You guessed it. The number which was stamped on the outside of the carton cannot be recognized by Microsoft, because they never generated it, did they? Instead, I asked to update my windows, which means that I leave my computer open for them to pick my IP number, address, because hey, somebody might simply have sold me a pirated copy masquerading as the genuine software. Is that supposed to be my problem if their right hands do not know what their left hands are sending out their own specified dealers. One exact month is the deadline they give me before they shut down my operating system. 29 days after loading, I switch on my computer to see that it has shut down and it is asking me to activate Windows. By telephone? On numbers which are not recognizable or operative? On Internet? How on earth am I going to the Internet to switch it on, if I cannot get access to the desktop where my broadband icon has to be activated to switch on the Internet, to get to MSN to activate the Windows. Sounds very much like a fairy tale in which a sparrow has to go around asking lots of animals to do some actions like water water put out fire because it is not burning the cow will is not eating the grass who has not done some else, which I asked it to do. Besides, why would I want to use an operating system which gives me this direction, when a notice appears upon my screen. Keyboard does not seem to be connected or is malfunctioning. Press any key to continue. DUH! So, that is the reason, because I have been supposed to be a fool twice by some geniuses, I do not intend to use Windows operating system, in my new computer. This time, I am going to choose any of these systems. And I hope none of them consider me stupid enough to follow the instruction of press any key, when the keyboard is not working. Linux / Variants MacOS MS-DOS IBM OS/2 Warp Unix / Variants

Title: Watch TV on Computer- Watch Satellite TV Come Hell or High Water
|
|
Watch TV on computer softwares are the best creation in recent personal entertainment. Many folks are now looking for how to connect computer to TV or get themselves hooked up to a computer TV tuner. There are many free computer TV channels but these tend to be unreliable due to heavy traffic from people looking to watch free TV on computer monitors. There exists, however, cheap ways to hook your computer to TV. Watch TV on Computer-Reviews of most reliable software. You may be wondering ‘how on earth do you find the best way to connect your Computer to TV. Well I’ll tell you this; its never easy, especially if you are relying on the internet to get an answer to that. Most of the results you get after making a search in Google, Yahoo or Msn search engines are sales pitches that do not necessarily answer your question. With everyone claiming their product is the best, how then do you make an informed choice? The last thing you want to buy is a software that doesn’t deliver what it said it would. And most do! A few months ago, I had the “honor” of being in such a position. I really wanted free TV on my computer to avoid sitting with the kids in the sitting room watching this or that series while fighting for the remote control. You see, it happens even adults need to watch the idiot box sometimes (read TV). The last thing you want is to look kiddish watching the same soap opera or program with your kid. Let’s face it some time you may want to watch a Tom and Jerry cartoon without your son thinking you are enjoying TV by day and endorsing his TV fixation. Most times you want to watch that cartoon or adult TV series when no one else is around. So how else convenient would that be had you the chance to watch TV on your computer in your seriously regarded study room or home office. I had heard that it is possible to watch free TV online. But something also told me that free things also come with a lot of restrictions and problems. So off I went to the internet to find a free Satellite TV site. I actually found a free TV website but the problem was that it was very frustrating to watch anything there. You see, since its free online TV, so many people are trying to watch it at any given time that the servers cannot cope. The result, very hard to access free TV websites. To be frank, I don’t think anything free is worth anyones time. So no free Internet TV for me. What next? I needed to find myself some way to access affordable TV on my computer that wouldn’t cost me an arm and two legs. A friend had told me of this new online TV softwares that are reasonably priced and would give enable me to hook up my computer to satellite TV. On searching ‘satellite TV software I got so many results from Google that all seemed like sales pitches. The exact results to my Google search query were over 10 million. How on earth was I to go through millions of results and get me satellite TV on my computer? Yes, you got that right…it’s impossible. Finally I decided to approach it from a marketer’s point of view. I assumed am actually marketing online TV Software and proceeded to look for a product that seemed to attracted most resellers online. And, Wallah… within seconds I could tell which satellite TV on computer software was favourite with online marketers. I guessed there has to be something good with such a software for it to attract such interest. Enter PC 2007 Elite Edition satellite on your computer program. This particular online TV software was simply at the number one position of all satellite TV for computer softwares. I decided to read their sales pitch and they seemed to know what they were doing at the least. On this website they even went a mile ahead of all the others to include latest movie trailers that I could watch and know what’s latest at the theatres. Even more interesting was the way I was able to select which movie trailer I wanted to sample from the mini- screen interface on their website. Simply awesome. My drive to watch TV on my computer free was so overwhelming that I decided to test the product. I figured that if only to test their so confident sales pitch, I would buy the software and if it didn’t work I would get my money right back. At least they promised that! In any case, theirs seemed a very reasonable price at a one time $ 49.95 for the software. Besides the price, they said that with the satellite TV on computer software, I would be able to watch 3000 TV channels from across the world. The website also says that TV will be available to me in 2 minutes flat upon payment and downloading the software. I decided for whatever its worth, I needed to try it. If only to test their claims. In any case their price for the software seemed ridiculously low for what it was offering. Well, well on downloading, I was actually able to watch TV from everywhere including Germany, Greece, Hungary, Iceland, India, Indonesia, Iran Luxemburg, Macedonia, Malaysia, Malta, Mexico, Mongolia, Netherlands, New Zealand, Poland, Portugal, Puerto Rico, Russian Fed, Saudi Arabia, South Korea, Spain, SriLanka,Sweden,Switzerland,Taiwan,Thailand,Belgium,Bolivia, Bosnia, Brazil, Canada, Chile, China, Colombia, Costa Rica, Albania, Algeria, Andorra, Argentina, Australia, Austria, Belarus, Cuba, Czech Rep, Denmark, Dominic. Rep, Egypt, France, Turkey, United Kingdom, Ukraine, USA, Vatican City, Venezuela, Vietnam among many others. I figured it wasn’t a bad deal to pay what seemed like a steal of a price to access so many TV channels across the world. For these prices I think anyone, just like I did, would want to test their product. Please visit my website for direction to watch latest movie trailers and download this Software. Thanks. Robert has worked for a satellite TV Company for many years.

Title: Working on what you need? How to find the computer systems or computer components you are looking fo
|
|
There is such a big emphasis placed on being computer literate, yet so much obscure jargon and hype about features. One has to be realistic about intended use and not get carried away by the hype. It has been the Onhop Online Computer Store's experience that new computer buyers often overestimate the performance requirement of their computer, incurring greater costs than is necessary. Consider the tasks for which you'll use the computer components or computer systems. Begin by making a list of activities you expect to do using your computer system. For example, do you want to use your PC for gaming, word processing, Internet access, graphics, music, or something entirely different? Will you use your computer system for a combination of tasks, or will it be dedicated to one particular task, such as small business accounting? Do you want to use your computer for applications, such as home security monitoring, that might require specialized hardware or software? Does anyone who will use the computer have special needs that might require adaptive equipment, such as a voice synthesizer or one-handed keyboard? If you are planning to use specialized peripheral devices or software, check their system requirements to make sure you purchase a computer that supports them. Before you start shopping, you should determine whether you want a Mac or a PC. To make this decision consider the platform used by the majority of your friends and coworkers. If PCs are the standard platform at work, you should probably purchase a PC for yourself. PCs are the choice of most businesses, except those focused on artistic endeavors, such as advertising agencies. Many elementary schools have standardized on the Mac platform, so if you are a teacher or have children who use Macs at school, that should be your platform of choice. However, you may have some special needs. If you intend to do, for example, architecture and want to run Computer Assisted Design or 3D software you may need a computer in the upper middle range perhaps with a larger sized screen. If you intend to make short films an iMac running iMovie is an option. Laptops are comparatively cheaper than they once were and may fall into your budget. Wireless internet access is now available in many locations like airport, bus station and etc.

Title: How Your Computer Mouse Works
|
|
Since the 80s or 90s—maybe even the 70s if you were a part of the “computer IN crowd”--kids have been playing with them, you’ve been clicking away at them, and your parents and grandparents have been trying to avoid the use of profanity around them! What is this precious item? It’s a computer mouse and they are the innovative way that we as computer consumers send our computer many of the specific signals that we want our computer to perform. What is a Computer Mouse? A computer mouse—like most engineering feats seem to be—is about an idea and then a sequence of steps. How does a computer mouse work? Keep reading to find out. How Your Computer Mouse Works1: The Ball You remember the ball mice right? Well, today not everyone uses a ball computer mouse as there are so many other computer mice to choose from. Today we have wireless mice, optical mice, RF mice and Bluetooth mice. You can also find an ergonomic mouse with a touch screen panel today—but before you go shopping, let’s go back in time to a slightly more antiquated ball computer mouse. This mechanical computer mouse, if not the first mouse was at least one of the first and obviously very widely used items. It has a little ball inside of it that would partially protrude at the base—just enough to let you wiggle it around with spherical, wheel-like ease. This ball however wasn’t just for your navigational convenience. On the contrary, when you, as the human commander, make that ball spin around, that is where the human and technology interaction begins. When you gave your mouse a tug to the right for instance the wheel would rotate and would in turn rotate a roller object (looks like a wheel, not a sphere) contiguous to the ball. This roller will “sense” directional movement along the X-axis and another roller according to my online source, “detects motion in the Y direction.”2 Then things really begin to get interesting. The rollers inside the computer mouse also happen to be connected to two shafts (one for each roller) and when the computer mouse ball is rolled and in turn rotates the rollers then the rollers rotate their respective shafts. The shafts are connected to a disk which has holes around the edges. There is also a light emitting diode (LED) on one side of the disk and a sensor on the other side that detects infrared light. My online source describes it well: “On either side of the disk there is an infrared LED and an infrared sensor. The holes in the disk break the beam of light coming from the LED so that the infrared sensor sees pulses of light. The rate of the pulsing is directly related to the speed of the mouse and the distance it travels.”3 In other words, you can move you mouse at a greater or lesser speed by just be rolling the computer mouse ball at a faster pace and in turn sending through more light flash signals via the disk, the LED and the sensor (infrared). Then of course, this “light information” must be converted to the computer’s binary language of 1’s and 2’s. This is done with an on-board processor chip that “can read “the infrared light signals” and then translates them into the binary language that is then sent on to other processors and areas of the computer that exact specific commands. Isn’t a computer mouse outstanding?! 1 http://computer.howstuffworks.com/mouse2.htm 2 http://computer.howstuffworks.com/mouse2.htm 3 http://computer.howstuffworks.com/mouse2.htm 4 http://computer.howstuffworks.com/mouse2.htm Marci Crane is a web content specialist for Innuity.

Title: Maintaining Your Computer
|
|
copyright@2007 William Robinson Being a computer technician pays nice money and has for a very long time. Why?..well,mainly becuase alot of new computer owners fail to learn how to use and maintain there new computer. Before purchasing my first computer back in 1998,I took an 8 hour class on the basics of operating a windows 95 system based computer..Even with the class,within the first few months,I had crashed the computer 3 times! This gives you somewhat of an idea about what we have here today..Alot of people now are getting computers becuase there friends have one,or to just get into the chat rooms,or the adult sites..point being..they dont know how to use a computer,much less maintain one. To save yourself alot of money and unneedless trips to the computer shop for repairs,there are a series of very simple steps you can take to keep your new computer running fast and efficient. Myself,I have windows xp home edition running on my computer..I find it to be the best system out there at the moment.The choice is of course yours as to what operating system you install on your machine. When you get your new computer home and you configure an internet connection,the first thing I recommend that you do is to get to the windows update site. The site will automatically update your new operating system with files to prevent people on other computers from accessing your data. Next step is to install an anti-virus and spyware program on your computer..If your buying a new computer from a big outlet,this is usually included with your purchase but not always.Make sure to inquire about this when purchasing your computer. Both these programs,the anti-virus and the anti-spyware are a must have in todays computer age..You can get good information from google(http://www.google.com}. Just type in anti-virus in the search box..you will get choices for alot of programs..same for the anti-spyware. Over time,you will visit alot of websites..Most of these sites has what are called "cookies".These are little embedded packages of data(files),that the sites you have visited leave on your computer to track your browsing habits. After awhile,these files need to be purged(deleted)from your computer. Other files that need to be purged at least once a week,are your temporary internet files and your history files. Failing to do this will really slow down your computer to a crawl and possibly cause a system crash,meaning you will have to re-install your operating system.. When you open up internet explorer,at the top left of the page,you will see options..Look for the Tools option.Left click "Tools",then left click "Internet Options".From there it should be straight foward for you.After you have deleted your temporary internet files and history files,click "OK" I do this at least once a day..really keeps my computer running fast. Now im going to share with you,some things you can do about whats inside of your computer(the case)or your computers "hardware". No matter how clean the surroundings where you have your computer placed,over time,alot of dust and particles gather on the inside..your motherboard,inside the power supply,on your cpu,all your cards(video,sound,ect..} I clean the inside of my computer every 3 months and I recommend all new users do it also.Here is how to do it: First,before you do anything,make sure the computer is unplugged from the outlet and is completely turned off! Next is to get a screwdriver for those little round screws you will need to undo to get inside your case. When both sides of the case are removed,you will need a can of compressed air..you can buy this from any computer store for under 5 dollars. You then spray all the areas inside the case..you will see the dust and dirt flyng off from the places you sprayed. Doing this 4 times a year(every 3 months)Is a great way to save alot of money and keep your computer running like its brand new! I hope you all have enjoyed my computer tips.

Title: a-guide-to-basic-computer-terminology
|
|
Let’s brush up our computer terminology! Ram? Mouse? One is an animal and one is a rodent right? Ram...that is the zodiac sign for Aries... If this is what these words mean to you than you can surely use this quick glossary of computer terminology. It would be a good idea to read through them before purchasing a computer because these are things you should know about first. If you already have a computer then these computer terms can help you know what to do if your new computer equipment is unfamiliar. Also, this computer terminology can help you if you have to call in for technical help. Okay let’s go! Cache: Cache is another type of memory kindred to RAM. The computer uses cache to quickly move data between the RAM and the CPU. CD-ROM Drive: Most new computers now come with a CD-ROM drive as standard equipment. A CD-ROM drive reads data from a disc. These CDs look like a music CD, but hold data instead of music. CD-ROMs also contain games, dictionaries, recipe files, and lots of other things that you can load onto your computer. CPU: The CPU, or central processing unit, is the brains of the computer. Most new Windows based programs use a Pentium processor or a AMD Athlon XP. New Macs use a different type of CPU called Power PC. Disk Drive:Virtually all computers come with a disk drive that can read and save information on portable diskettes, also called floppy disks. You can use floppy disks to save information or to load new software onto your computer. Hard Drive: The hard drive is also called the hard disk. You will probably never see it because it is nestled inside your computer. It's the computer's electronic filling cabinet, and it stores the computer's operating system, files, programs and documents. Keyboard: Just like a typewriter keyboard, this device is the primary way of inputting data into the computer programs. Megahertz (MHz): This is the clock speed of the microprocessor. The higher the number, the quicker the information is processed. MHz relates to how many millions of instructions can be processed per second. Memory:This is the circuitry or device that holds information in an electrical or magnetic form. There is read-only memory (ROM), which is information primarily stored on a disk, and random-access memory (RAM), which is chip-based storage inside the computer. Memory is typically measured in megabytes (MBs). Modem:This mechanism connects a computer to a phone line so information can be sent from one computer to another or the user can access an on-line service or the Internet. In view of the popularity of the Internet, a modem is now considered basic equipment and comes on practically all-new computers. Most modems come with fax capabilities. Monitor: An output device that allows you to see what you are doing (it is what you are looking into right now to see this). Most computers come with 14 or 15-inch monitors. This size is good for most people's needs. Larger 17 or 21-inch monitors also are available, but may cost more. Myself, I prefer the 17-inch. Motherboard:The motherboard is the circuit board that everything in the computer plugs into. The CPU, RAM and cache all plug into the motherboard. Mouse: The mouse is another input device that makes getting around in your computer easier. It is a handheld object that is good for doing tasks such as moving and pointing to objects on the screen, and can replace the function and control keys of the keyboard. (If you need a lesson on how the mouse works and how to use it click here for a tutorial.) Printer: A printer is an essential part of the computer if you want a hard copy of your work. There are four types of printers on the market: dot matrix, inkjet, bubble jet and laser. The dot matrix is the most basic. Most inkjets and bubble jets can print color and graphics, and a laser printer offers the best resolution at the highest speed. RAM:Computers save data in two ways: on the hard drive and in random access memory or internal memory. New computer buyers should look for models with at least 16 MBs of RAM (or more, depending on what types of programs you will be running). Make sure that the computer can be upgraded. Scanner:A scanner is a useful accessory to have if you are working with lots of artwork or photos. This device can copy written documents, pictures or photographs directly into your computer. There are three types of scanners: handheld, hopper-feed and flatbed. Sound Card: This device allows your computer to reproduce music, sounds and voices. Make sure you have a sound card if you are planning to play multimedia games. Video Card: The video card is the part of the computer that sends the images to the monitor. Well there you have it, a quick course on computer terms. I hope it has helped to guide you in your purchase of a new computer; or to help you with the one you have. Did you find this article useful? For more useful tips and hints, points to ponder and keep in mind, techniques, and insights pertaining to computers, software, hardware viruses, spyware etc. do please browse for more information at our websites.

Title: What To Think About When Buying A Computer
|
|
Buying a computer is a big responsibility. You don’t just go to a store and demand to be a given a computer. You need to know what you want first before you spend a lot of money on a computer unit. There are many points that you need to consider when buying a computer. To help you decide which computer is best for you, here are some pointers. Purpose Of Buying A Computer Before you buy a computer, you need to ask yourself first what you need the computer for. If you need a computer for your general office work, you do not really need a very powerful computer. On the other hand, if you intend to use you computer to run some complicated and complex programs, you will need to buy a more powerful computer. Determining your purpose is crucial because this can be the springboard of your decisions making so do not cut corners when it comes to this task. Determine Your Budget To know how much you can afford to spend on your new computer, check your finances first. Add up all your income for the month and subtract all your possible expenses. If your balance turns out to be negative, meaning your expenses is higher than your income; you better reconsider buying a new computer. On the other hand, if your balance sheet shows a positive balance, do not party just yet; you still need to evaluate how much money you have before you splurge on a super computer. Check you balance again and see how much money you can afford to spend without draining your bank account. Choosing Your Computer When choosing your computer, you need to pay close attention to the Processor or Central Processing Unit (CPU), Memory or Random Access Memory (RAM), hard drive and the monitor. The CPU handles almost all of the computing functions of the computer so you need to make sure that you get a computer with a good CPU. On the other hand, the RAM of the computer handles the task of storing information thus it is imperative that you get a RAM that is big enough to handle the type of information that you are going to store into it. Buying Online Buying your computer directly from the manufacturer through their online stores can be very advantageous. Not only will you be able to get the computer at a cheaper price, you can also be sure that you get exactly what you want. Another interesting about these online companies, like http://hpcomputersonline.com, is that they also offers other products such as the computers, desktops, pc, workstation, drivers, laptops, notebook, digital camera, ink, toner, cartridge, printer, scanner, software, monitor, projector, server, television, TV, storage, networking, printer supplies, computer accessories and IT solutions.

Title: Computer Hardware guide- Get all about Computer Hardware
|
|
Physical parts of computer come under the category of computer hardware. It can be changed once in a while in comparison with computer software. Normal users don’t see most computer hardware because it is enclosed as embedded systems. The term computer hardware is generally used for personal computers. Internal computer hardware consists of motherboard having central processing unit and random access memory. Random access memory provides temporary storage of data where as CPU is used for doing all type of calculations. Second major component of computer hardware is Bus that is used to make common connection between several circuits. People can choose any type of buses as per their needs. Generally these are PCI bus, PCI-E or AGP bus, ISA bus that is outdated and UCB that is commonly used. Computer can’t be run without power supply that is case including transformer, voltage control and fan. Computer hardware includes storage controllers that are helpful in controlling the hard disk, floppy disk, CD-ROM and other drives. These can be assembled on the motherboard or expansion card directly. Video display controller is used to generate output for the computer display. Computer bus controllers are also come under computer hardware. These are used to connect computer to external peripheral devices like printers and scanners. Sometimes computer hardware includes some removable media writers such as CD, CD-ROM Drive, CD Writer, DVD, DVD-ROM Drive, DVD writer, DVD-RAM Drive, Floppy disk and Zip drive. These are not permanently fixed in the computers and whenever you want you can remove them easily. Tape drive, Internal storage and hard disk of the computer offers different levels of data storage like tape drive offers backup or long-term storage, Internal storage keeps the data safe inside the computer for later use while the hard disk offers medium-term storage of data. Sound card usually translates signals from the system board into analog voltage levels. It has terminals to plug in speakers.

Title: Is Your Computer Really Secure?
|
|
Have you thought about computer security at all? Most likely not. Many unsuspecting individuals believe that computer hackers only hack into corporations and rich people. This is far from the truth. So beware. Computer security does not involve just warding off bad hackers. Every day your computer is susceptible to threats regarding your computer system and the information you store on your computer. Identify theft has become a prevalent problem in the past few years. Credit card companies and banks have had problems with their computerized data being comprimised. Hackers have broken into their system, putting their millions of customers at risk. If hackers can hack into well secured systems like these then they can most likely hack into your personal computer more easily. Hackers benefit financially from stealing your personal information off your computer and using it in a variety of ways. The sad thing is that happens to innocent people every day. Don't care about identity theft? Why not? What about the amount of time and money you have put into your computer? If your computer has a virus it can destroy your memory and hard drive causing you to lose all your information. Your computer will be an simple target if you dont' have a security system. Your unprotected computer will eventually fall prey to a computer virus. A computer virus can be catastrophic. To avoid the disastrous and awful effects of a computer virus, you must set up a security system on your own computer. Make sure that you have a firewall installed. A firewall can analyze information from the Internet and check to make sure it is not harmful to your computer. If the firewall determines that the information is harmful then it will block it. A firewall should be the first component of your computer security plan. The next step is to set up anti-virus software on your computer system. Anti-virus software provides many tools that will stop anything that mistakenly passed through your firewall. Hackers have been known to break into the computers and use them as a clone computer. Don't let this happen to you. Think about a cloned computer. It is a tool for the hacker. The hacker will make the cloned computer do anything they want it to from stealing e-mail to breaking into other computer systems. You can supply a shield against this by analyzing all your e-mail messages with anti-virus software. Don't open attachments unless you were expecting them. Hackers thrive on placing disastrous viruses in attachments. Stop them quickly and effectively by not opening attachments and deleting the e-mail message right away. Spyware is a term you should add to your vocabulary. Hackers can use this software to sneak into your computer and spy on you. Spyware roots around your hard drive and absorbs any personal information. Spyware tends to slow down your system and put your personal information up for anyone to see and use. You can purchase anti-spyware of download it for free from browers and software providers. It is good idea to add anti-spyware software to your computer security system. Computer security has become vital to protecting you and your computer in this day and age. The Internet is full of predators and you must safeguard your information and computer from them. Whatever you do, make certain that you make computer security a priority before it is too late!

Title: What You Should Know Before Buying Computer Equipment
|
|
With computer equipment today almost any of them will adequately handle what most people need to buy a new computer for; word processing, basic office, internet surfing and email. Which you can buy for about $1000. or less! But if you are into digital videos, photo editing, music, or manage a large database you will need more than the basic Desktop PC or Laptop. This higher end computer will cost you around $1500-$2000.
(CPU) Processors:
There is always a lot of change in the computer market, but no matter what the upgrades there are always two basic choices to be made when purchasing computer equipment:
1) brand 2) speed. To buy a new computer that handles standard office and Internet tasks any processor will work.
Need more 'power' in your computer equipment? Then the Intel Pentium4 or the AMD Athlon XP (great for graphics and photos which use a lot of memory space) is for you.
If you buy a new computer one or two levels from the top you will only lose about five percent per tier performance but you can save a couple hundred dollars!
(RAM) Memory:
Memory is very important because optimum running of your computer equipment is dependent on enough RAM. The minimum amount should be 256MB, for better performance you should get 512MB. If you can afford to buy a new computer with more, you should. It's worth it because you can keep more applications open and it will easily handle memory hogs like Photoshop and music applications!
Monitors:
When buying computer equipment look for a monitor that is at least 17" with a resolution of 1280 by 1024 pixels. A Desktop PC with a 19-inch monitor gives you 20 % more screen area. If you can spend $300-$450 on a monitor when you buy a new computer you might want to get a 15" LCD because it has the same viewable area as the 17" CRT and takes up much less space.
Hard Drives (storage):
Most hard drives sold today will provide more than enough storage. The basic computer equipment comes with 40GB or larger, which is plenty for most tasks. But for working with graphics, video, music, or large databases 80GB should be the minimum you settle for. 7200-rpm drives give better performance. But for the best performance get a computer with 8MB of cache.
Warranty and Tech Support:
A one-year warranty on most computer equipment is enough, because most problems seem to happen in the first year. If you want you can get an extended two to three year warranty for around $150. to $200. If you buy a Dell you can get priority call routing to tech support for a year for only $39.
