Surf most people buy a computer on the Internet, send / receive e-mails and, occasionally, to work with text files or other documents. Today, even the computer as "poor" can handle this without problems and very cheap to do. This is all you need and you have no right then all the help of computers.
But if your needs are greater, you should change your media files, images, databases you need, you want to play the latest games ... You have to think of a computer generation. Alsoif the technology progresses at a rapid pace, the acquisition of a computer at the top you will save money in the future, it will face (up to a point in time) future software requirements. Perhaps one of the most active market segments, sales of computers is a segment of PC games, computer games. Members crazy to spend hundreds of dollars on the latest generation graphics card, and not just dual-core processor, but quad-core for maximum power. Do not be deceived, is to play a game not just a hobby, a passion forones that give you the money. Gaming industry billions annually.
But enough for now ... We speak of computer components and see what you know, if you want to buy a computer, you must:
Wd World Book
Processor
As I said, with a computer to the Internet for applications such as e-mail and documents do not require the implementation of the computer. But if you want more, then the processor can do whatever you want.
At this point processor market battle between Intel and AMD,two American companies. In many tests, Intel Core 2 Duo are better than rivals such as AMD Athlon 64 X2. Do not think, however, that AMD processors are weak. It 'just a moment the situation was not a time, before AMD Intel. However, in this case against Intel are both AMD dual-core processors (dual core - two independent processors connected in a circle on the same silicon plate), so that the processors that run faster multitasking activate (different operationsperformed at the same time) with a good performance for games and multimedia.
If you still want a dual-core processor, but not enough money for one of the above you can find dual-core processors with the lowest prices, but usually falls in performance. Computer was used or refurbished, are good options for a low budget.
This is a game are fans, remember that even if a quad-core processor sounds great, a dual-core is definitely sufficient for most users. Right noware just some applications, the quad-core processors and secure, you need not be their full potential.
Memory
Computer memory (an electronic component that receives information and instructions, so that the processor can quickly access) is measured in capacity. If more memory is installed, the applications are running smoothly and the system will work better. Memory is an essential part of the computer, without him does not work, are pre-installed for any reason.However, every time a new memory module to be added to increase the capacity and operations.
Motherboard
A motherboard should have bought thinking about the future and, of course, depending on the facilities it offers. The second generation of SATA ports (which reaches a transfer rate of 3 Gb / sec), high-definition audio on board, and even two graphics cards (SLI or CrossFire) can help a lot in the presence and in the future.
A mother very much appreciatedIntel "Skulltrail." Its configuration is as follows: for dual-socket LGA 771 procesor support Penryn chips to 45 nm technology and supports up to four x16 PCI Express 1.1 slots, two PCI 2.3, six SATA 3.0 and two eSATA ports.
BUT before you buy a motherboard, if all the components you want to buy you want, select the desired configuration and then go shopping
PC Case
A good computer case might be the best day, if you want to upgrade. It should beadd any new components should be easy to open and allow you to move things around and everything should be properly ventilated.
If you plan to keep your computer in a longer period to allow room for future home PC components. Let free slots for memory cards, one for a sound card, etc..
The most common cases are ATX format. ATX specification not only specify where you should connect the pins on the back of the case, but also show as a sourceto use.
You can use different shapes and sizes, such as MicroATX, NLX, BTX (ATX format change seems driven largely by Intel).
Video card (graphics card)
Graphics Card for the production of all the images on the monitor and can be pre-installed on the motherboard or purchased separately. Their main characteristic is power. The integrated graphics card typically use system memory to run, while the dedicated graphics card to use their own dedicated memory. For the vastMost users, integrated boards are sufficiently progressed, however, if you want games, graphics and other multimedia programs, we recommend a dedicated graphics card.
If you already inserted into a computer, before you go shopping to find out what kind of system board. Or, if you try a computer, a system that can be PCI Express x16 slot for graphics cards. Although there are motherboards with AGP and PCI slots are already in the past.
Hardisk
The size of the hard disk has increased dramatically over the past 12 months, reaching the present size of 160 GB to 1 terabit (1000 GB). If planning to store large amounts of data, then the higher the better.
Today, most hard drives are Serial ATA 7200 rpm and are, players will appreciate the Raptor X 150 GB hard drive with 10,000 RPM Western Digital.
Control
No matter how it looks, but what it does. Some things you should keepbecause if you buy a monitor optimal resolution (1024x768). For higher resolutions, you need a better graphics card. Remember, if you want a 30-inch monitor. Remember, the distance from the monitor. It is the old problem of cathode ray tubes, but the entire screen with your eyes while working, otherwise the eyes will be tired very soon (and health problems could also appear).
Most people use 17 "or 19" monitor. Another optionwould be a 22 "monitor, especially since the price difference is relatively small compared with the 19" s.
All computers need an optical drive. Optical devices are very different and can have different options. It is unlikely to be a new system is less than a DVD-ROM (read discs but not write) is installed, but most systems are (read and write / rewrite CD / DVD) DVD-RW dual-layer multi-format. Find by DVD players write dual-layer DVDs, and offers the possibilityLightScribe Direct Disc Labeling for (can burn a disc with a label).
The highest quality of computers have Blu-ray Disc and HD DVD devices. But the price is rather high (three or more from a DVD-RW).
USB devices are becoming increasingly popular and has come to DVD from the convenience of mobility and increased lifespan rivals.
Network Map
Today, the Internet is part of our daily life. Every new computer has installed on an internal network card. If youwant something more, try using a router or gateway.
Sound Card
The office is the integrated sound card is probably more than enough. At home, you'll probably want surround sound, the implementation requires a sound card. The prices are not high, there is no problem to find and buy. Do not forget that sound quality is required and a series of wet high-quality speakers.
The new systems offer quality sound, because they were already integrated sound cards with capacities of 7.1,24-bit (32 bit) and 192-kHz audio.
Keyboard and mouse
The current trend is to use a wireless keyboard and mouse, but there are a lot of systems that use USB ports. The keyboard is easy with just basic functions, or a real machine with lots of buttons worthy of Star Trek. Today is the most famous optical (using a small camera to detect motion and movement much better).
Operating System: Linux, XP or Vista?
For those who do notAlso consider using an operating system based on Linux, I suggest you rethink again. Yes, there are many options to be developed under Linux but the same goes for Windows. Linux interface is comparable to that of Windows (for example, try the Ubuntu distribution of ubuntu.com).
Windows XP is the best selling operating system. Most applications have been built especially for them, the drivers were written for the components, etc. ... If you do, could be Windows XP, but soonoffered for sale. But do not forget to update frequently. Purchased the system more, is the most attacked. It has its problems, some of them severe. Remember to buy an antivirus, antispyware and firewall.
Windows Vista is a step forward in terms of safety features, like more and better than XP. And 'cool as the design, but also eat a lot of resources. Unfortunately for Microsoft, Windows Vista, which should not be a replacement for XP to make their goal, its usershappy.
So, are you ready to buy a computer? Before leaving to go shopping, take a minute and read the following suggestions:
Check the warranty and support offered: the majority of problems (if they appear) in the first year, one year warranty should be sufficient. In addition, the better.
Do not buy additional software if you do not need them. Buying your computer's operating system (if you chose Windows), a suite of office applications and a (free antivirus virus can be foundInternet. AVG or Avast are good choices).
Look at the number of connections. More, the better you will use them in time.
Buy what you need. The promotions are interesting, but perhaps not much help.
Buy a little 'more than the minimum that you use your computer as long as possible. Although it seems a hard disk of 160 GB is sufficient, over time you will need a bigger hard drive. Get a list with minimum configuration, and then add the additional"Ingredients".
Check the connections for the monitor. If your graphics card has a DVI output, the monitor must be a DVI input.
If you do not buy. Good salespeople know that they will provide you with all types of components in order to attract your eyes. Do not buy if you do not need them right away. In a few months when you need it, the product will be half price.
Hope it helped. And do not forget. If your budget is low, you may be good systems Refurbishedat a good price.
