How to buying the perfect PC
By Dee Kerr
PCs have become a staple in every home. Without PCs, you will find it hard to
stay connected and to even do the work required of you in school or in the
office. With so much PC packages being shoved to our throat every time we go to
department stores and computer shops, you'll really get quite confused on what
you really need and what PC package will fit your budget and lifestyle. To help
you through this dilemma, here is a brief backgrounder of the parts of PCs that
you should get to know.
Processor
This is one of the three primary components of your PC. The processor is the
part that determines how fast your computer process information. Intel is still
the leading brand in processors but competitors such as American Micro Devices
(AMD) are slowly catching up, offering cheaper alternative. In shopping for a
processor, one should consider the following:
Clock speed - this will show the number of instructions that
a computer can execute in a second. This usually comes after the brand name.
Processors nowadays are already set at the gigahertz range.
Cache memory - this stores the data that were previously
accessed. This simplifies the work of the computer as it would not take twice as
long to access information already stored in memory bank. Without a cache
memory, much of the work will fall on the RAM (Random Access Memory).
Operating temperature - some processors easily heats up.
Before buying, make sure that you have asked about the operating temperature
just in case you need to buy additional fans or put the computer in an
air-conditioned room.
RAM (Random Access Memory)
RAM serves as the temporary memory of the PC, containing information that are
needed for the computer and the programs to function. In addition to processors,
RAM also determines the speed of the computer. The higher the RAM, the faster
the computer is in accessing information and responding to commands.
Motherboard
This is where all the parts of the PC's CPU (Central Processing Unit) are
attached. Some motherboards already have videocards and soundcards embedded on
it while others don't. what is important however is to choose a motherboard that
is compatible with your RAM and processor. Incompatibility of PC hardware can
cause major problems and may even lead to the breakdown of your computer.
Hard drive
This is the part where you store all the information in your PC. Picture a
floppy disk with much much larger storing capacity. The hard drive serves as the
permanent memory of your computer. Here you install all your programs and save
all the documents that you need. It is also important that you buy a hard drive
with really big capacity especially now when people are so used to storing
multimedia files that may use up a lot of hard drive space.
Video cards
This is the part of the computer which determines the quality of the
multimedia images that you will view. The higher the memory of the video card,
the better is the picture quality and the colors. Also, video cards are also
responsible for how fast multimedia images are accessed. This is especially
needed if you use your computer for multimedia activities such as watching a
movie or playing video games. About the Author Dee Kerr makes it easy to find a PC that suits your needs, quickly & easily. Learn the essential keys to look out for. visit: Pc buying guide website, or want to build a PC?
