Cpu Ram

August 19th, 2012

What does the CPU, RAM, and Graphics card determine individually in a computer?

I was just wondering if all of the above does affects the same thing and they must be in proportion? What must one look out for when buying a computer? Should he or she just solely look out for the processor speed? Help is really appreciated thanks!

The central processing unit (Often called CPU) is the brain of a computer and this the location for processing of information and data on the computer.
A processor processes binary data and will retrieve some data, perform some process on that data, and then store the result in either its own internal memory which is know as cache or the systems memory.
If the information for the process say 32-bit then the processor can process 32 bits of data at one time, if it says 64-bit, then it can process 64 bits of data at any one time. So a 64-bit processor is twice as fast compared to a 32-bit processor.(http://www.networlddirectory.com/general/computers/hardware/cpu.html)

go here (http://www.pcmag.com/article2/0,2817,1166949,00.asp) to get your mind wrapped around RAM and what it means in a PC buying situation.

and here (http://computer.howstuffworks.com/graphics-card.htm) to learn that same info as applied to purchasing a graphics card.

if it's specific computers that you want to compare and contrast, looking them up on consumerreports.com that'll tell you what people love/hate about machines that they've used. Hope this helps some.
