CPU parts
The computer system includes the CPU parts which
are all necessary for the system to work. The central processing unit or (CPU)
works by carrying out the instructions to the computer program, performing the
arithmetical and logical instructions and the processing of the input/output
operations of the system. No wonder why, the CPU is considered as the brain of
the computer.
Generally, CPU Parts are
basically grouped into:
The Arithmetic Logic Unit or ALU. These are composed of CPU parts that
perform the logical and arithmetic operations of the computer system.
Arithmetic operations include multiplication, division, addition and
subtraction; while the logical operation include comparison of numbers like
identifying which is lesser, more or equal.
Control
Unit or CU. This is one of the CPU parts that
will carry the instructions from the RAM (Random Access Memory) and interpret
those instructions in order for the system to execute the instructions. This
time, the ALU’s help is needed if it concerns logical and arithmetical
operations. However, it must be noted that other CPU parts are
the one that will perform or execute the instructions. The CU will just direct
the CPU parts to
do it. Meaning, the control unit will just serve as means to link the ALU and
the memory.
Memory.
This one of the most important CPU parts. The processor works with the built in
memory it has. The memory cell will store the data temporarily in order for the
system to execute the instruction. It is now the role of the CU to get those
information from the memory. Then the process of interpreatation is handled by
the CU and then, ALU takes its role after the CU directs the instructions.
The CPU parts of
the computer system can tell whether the computer system can work accordign to
your needs. Hence, when you are to buy one, make sure to check the CPU
and not the outside appearanc of the computer unit.
