What is the full form of CPU?

Answer»

CPU: Central Processing Unit

The full form of CPU is “Central Processing Unit“. CPU is also called as processor, central processor, main processor or microprocessor. CPU is also known as the brain of the computer. The central processing unit (CPU), is the unit that performs most of the processing inside a computer. To control the flow of instructions and data to and from other parts of the computer, the CPU relies heavily on a chipset, which is a group of microchips located on the motherboard.

Traditionally the term CPU refers to a processor consisting of a control unit and an arithmetic logic unit.

Central Processing Unit (CPU) = Arithmetical Logical Unit (ALU) + Control Unit (CU)

Components of CPU

The CPU is broadly divided into three main parts.

Arithmetical Logical Unit (ALU)

It is a significant part of the CPU. It is responsible for the supervision of all numerical and logical functions, such as subtraction, addition, division, multiplication etc.

Control Unit (CU)

CU is the main component of the CPU. It directs a task to the whole system, and it regulates all the computer activities that occur.

Memory or Register

A register is a particular type of device for memory. The memory stores the information which the processor has to process or already processed.

History

Some important events related to CPU history are as follows:

YearEvent

1823	Baron Jons Jackob Berzelius discovered silicon (Si), which is the processor today
