CPUs
A processor is definitely the most important
part of the inside of a computer. And it is also known
as the CPU, or Central Processing Unit, but the reason
this element is like the heart of the PC is because
it is the mainframe, or brain, since it makes all
the decisions and all of the data processing
along with the calculations that allow the computer
to operate in a flawless matter.It is always located
on the motherboard inside the computer and is plugged
into the processor socket. The processor consists
of three main parts which are the control unit, the
arithmetic and logic unit (ALU) and memory (registers,
cache, RAM and ROM) as well as various temporary buffers
and other logic.
But there is a specific way in which
the processor works, that being that the control unit
fetches instructions from memory and decodes them
to produce signals which control the other part of
the
computer. This may cause it to transfer data between
memory and ALU or to activate peripherals to perform
input or output.
There are many different types of processors
that have been developed over the past few years.
Some of the more popular older versions such as the
AMD Thunderbird, Duron, and Athlon were very common
during their time period. But now throughout the present
the company corporation known as Intel has seemingly
been conquering all other competition with there line-up
of Pentium processors. There very first one came out
with all of the other older versions, it was called
the X86 Pentium. This processor was just practice
for the growing company until they released there
newer model called the Pentium I. From there they
continued to branch with the Pentium II, Pentium III(i686),
and now the present model the Pentium IV. AMD is the
second-largest supplier of x86-compatible, and the
largest supplier of non-volatile flash memory.
