Computer: An electronic device which is capable of receiving information (data) in a particular form and of performing a sequence of operations in accordance with a predetermined but variable set of procedural instructions (program) to produce a result in the form of information or signals. A person who makes calculations, especially with a calculating machine.
Central Processing Unit (CPU)
A processor is the logic circuitry that responds to and processes the basic instructions that drive a computer.
The
four primary functions of a processor are fetch, decode, execute and write
back.
The basic
elements of a processor:
-
The arithmetic logic unit (ALU),
which carries out arithmetic & logic operations on the operands in
instructions.
-
The floating point unit (FPU), also known as a math coprocessor that manipulates
numbers more quickly than the basic microprocessor circuitry can.
-
Registers, which holds instructions and other
data. Registers supply operands to the ALU and store the results of operations.
-
L1 and L2 cache memory: The inclusion in the CPU
saves time compared to having to get data from random access memory (RAM).
The two main competitors in the
processor market are Intel and AMD.
Performance of CPU:
Performance
of PCs, which include multimedia machines and workstations, will give
you more power of complex creative or math and scientific projects. Faster
processors with four, six, or even 18 cores make quick work of your task. More
memory (8GB to 32GB) is installed, so you can keep larger images on screen
while editing a video, rendering a 3D model, or processing a humongous
spreadsheet full of numbers you have to graph. You’ll also find extra storage
in the form of large hard drives and SSDs that will let you hold a multitude of
work documents and program library file.
