Computer - CPU(Central Processing Unit)
The CPU contains the following features:
CPU is regarded as the brain of the computer.
CPU performs all types of data processing operations.
It stores data, intermediate results, and instructions (program)
It controls the operation of all components of the computer.
There are three components of the CPU itself.
Memory or storage unit
Control unit
ALU (arithmetic logic unit)
Memory or storage unit
This unit may store instructions, data and intermediate results. When the unit is required to provide information to the other computer units. It is also known as the internal storage unit or the main memory or primary memory or a random access memory (RAM).
Its size will affect the speed, strength and ability. Main memory and secondary memory are two types of memory in a computer. Functional storage units are:
All its stored data, and processing instructions necessary.
It stores the intermediate results of processing.
The end result is stored before it is processed, the results are released to the output device.
All inputs and outputs are transmitted through the main memory.
Control unit
Operation of all components of the computer control unit, but does not perform any actual data processing operations.
Features of this machine are:
Other unit which is responsible for the transmission of control data and commands between computers.
It is the management and coordination of all units of the computer.
indicating that it obtained from the memory, interpret them, and the instructions of the computer.
With the input / output device for data transfer from memory or communicate results.
It does not handle or store data.
ALU (arithmetic logic unit)
The unit consists of two sections, namely
Arithmetic unit
Logical part
Arithmetic Division
Function calculation unit is to perform arithmetic operations like addition, subtraction, multiplication and division. All complex operations are accomplished by repeating the above action.
Logical part
Logic part of the function is to perform logical operations, such as comparing, merging selection, matching and data.
