2. What is the CPU?
This is the "brain" of the computer; it
reads and executes program instructions,
performs calculations, and makes
decisions.
3. Introduction about the CPU:
In order to work, a computer needs some
sort of "brain" or "calculator". At the core
of every computer is a device roughly the
size of a large postage stamp. This device
is known as the central processing unit, or
CPU for short.
4. More than about CPU:
The CPU is reponsible for storing and
retrieving information on disks and other
media. It also handles information on
from one part of the computer to another
like a central switching station that directs
the flow of traffic throughout the
computer system.
5. The role of the CPU :
The CPU or central processing unit or
processor is the hardware within a
computer system which carries out the
instructions of a computer program by
performing the basic arithmetical, logical,
and input/output operations of the
system. The CPU plays a role somewhat
analogous to the brain in the computer.
7. Important works of the parts CPU:
Primary Memory : The primary memory is also the
temporary memory and it is used to store the data that is
currently required by the cpu the primary memory is fast
then secondary memory and it has no large storage .
Arithmetic Logic Unit (ALU) : The main function of ALU is to
perform different arithmetic or mathematical operations
such as addition, subtraction, multiplication and division. It
also supplies or gives out the information and results for
computation to the outside world.
Control Unit (CU) : Its functions are to ensure that the
program instructions are carried out in the desired
sequence and to control and co-ordinate the flow of data
between the CPU and the input-output devices.
8. The aim of presentation :
Study of solutions CPU note that CPU of
the most important elements of a
computer because Silverlight. Orbit task
in computer operations and the
computational and storage task.And so is
the computer without CPU Nothing .
9. Factor word :
When you click to execute an application, the
raw instruction is first fetched from the hard
disk (sometimes from the memory) and sent
to the CPU for processing.
When the CPU receives the instruction, it will
execute the logic and compute the result.
Once the CPU finishes processing, it will send
the result to the respective device to output
to the user.
