To buy the first computer must consider the needs, that is, the purpose behind a computer for basic needs when writing a paper or in connection with the world via the world wide web, or just playing games. If it's just to prepare your papers, then you can get a computer with minimum memory and the system 386. If the requirement is the version of the word processing program and the requirement is slightly more disk space will be needed as well. If you need Internet and download information from there, then the system must be technologically superior. Once you have decided on the requirements, the next thing to consider is the amount of money you can pay for it depends on the quality of software and monitors can be determined. To save money though, do not compromise on the quality of the important things like the monitor, processor, memory, disk space and the like. You can save a little on the printer or the speaker but not on disk space or CPU (Central Processing Unit). Let me share some details about the main components of the computer.
The selection of the CPU is a complicated one and we have to choose between Intel and AMD. Relative speed and the number of cores is different from one processor to another. Since this is a complex component, before buying one should obtain detailed information about each brand and perform comparative analysis. Then came the RAM memory. DDR2 is a type of memory commonly used computers, but for high-end computers to DDR3 memory is being used even though expensive.1GB enough memory is standard, but if you can afford 2GB of memory space, the better. Memory speed may have an impact on performance, as well as faster memory, better is the performance of the computer. When buying memory, avoid buying the DIMM so you can upgrade your computer memory components as and when you want.
The next thing is the Hard Drive of the computer, which is important for the size and speed. It is better to have a big drive, which will work faster, have better performance and capacity. Most hard drives use a Serial ATA interface because it is easy to install even though almost no difference between Serial ATA and IDE standards. Then comes the Optical Drive, which is a CD and DVD drives. In most systems sold today already have a DVD burner but it is always better to get a multiformat DVD burner that supports both + R / RW and -R/RW formats.16x should be the ideal speed. Another thing you should notice is the video card only if you're into 3-dimensional graphics. There are different kinds of cards that you can choose from if you want the card but then the choice should be based on performance, memory space, and the output connector versions.
The main component is a computer monitor, so when buying a computer, one should try and invest a little more on the monitor. There is always a choice between CRT and LCD monitors, but then the current LCD monitor manufacturers provide and which has become the standard for size is less, so it occupies less space and consume less power.So This is a major component of a PC to be purchased after put some thought, apart from this, upgrade, back-up, repair, obsolescence and availability of spare parts should also be considered.
