Guidelines for buying a good computer
PCs have become a staple in every home. Without a PC, it will be difficult for you to stay connected and even do the work you are asked to do at school or in the office. With so many PC packages being shoved down our throats every time we go to department stores and computer stores, you will really get quite confused as to what you really need and which PC package will fit your budget and lifestyle. To help you overcome this dilemma, here is a short rundown of the parts of PCs you should know about.
Processor.
This is one of the three main components of your PC. When buying a processor, one should consider the following:
Clock Speed - This will show the number of instructions a computer can execute in one second. It usually appears after the mark. Today's processors are already configured in the gigahertz range.
Cache memory - Stores previously accessed data. This simplifies the work of the computer, since it would not take twice as long to access the information already stored in the memory bank. Without a cache, much of the work will fall on RAM (random access memory).
Operating temperature: some processors heat up easily. Before buying, make sure you have asked about the operating temperature in case you need to purchase additional fans or place the computer in an air-conditioned room.
RAM (random access memory).
RAM serves as temporary memory for the PC and contains information necessary for the computer and programs to function. The larger the RAM, the faster the computer will be in accessing information and responding to commands.
Motherboard
This is where all parts of the PC's CPU (Central Processing Unit) are attached. Some motherboards already have embedded video and sound cards, while others do not. However, the important thing is to choose a motherboard that is compatible with your RAM and your processor. Incompatibility of PC hardware can cause major problems and may even cause your computer to crash.
HDD.
This is the part where you store all the information on your PC. Imagine a floppy disk with a much larger storage capacity. The hard drive serves as your computer's permanent memory. Here you install all your programs and save all the documents you need. It is also important that you buy a hard drive with a really large capacity, especially now that people are so used to storing multimedia files that they can consume a lot of hard drive space.
Video cards
This is the part of the computer that determines the quality of the multimedia images you will see. The larger the video card memory, the better the image quality and colors. Furthermore, video cards are also responsible for the speed with which multimedia images are accessed. This is especially necessary if you use your computer for multimedia activities such as watching a movie or playing video games.
