CPU Full Form in Computer: CPU types, Diagram, History

What is the Full Form of CPU?

CPU full form in computer is derived as

C – CENTRAL

P – PROCESSING

U – UNIT

      

CPU Definition

CPU full form is the Central Processing Unit. CPU is also famous as the brain of the Computer, a Processor, Central   Processor, microprocessor, and main Processor. CPU is the part of a computer that manages all the other parts of the Computer.

The Central Processing Unit works all Input/Output, Logical, Aptitude, Managing, Basic arithmetical Operations in the Computer Program.

Function of CPU

It receives instructions from hardware and software and provides output accordingly. It stores all the essential programs and other application software.

CPU is communicating with input and output to devise with each other. CPU is installed in the motherboard on some specific area, which is known as CPU socket.

CPU Components

  1. Memory Unit (it’s also called as MU)
  2. Arithmetic Logic Unit (it’s also called as ALU)
  3. Control Unit (it’s also called as CU)

1) MU (Memory Unit)

All Informations, Data, Results, Directions are stored in MU. It’s also known as SU(Storage Device)

When Computers need information, this part provides all information, Data, and M.U. size also affects working hours, Power, Speed of the Computer.

Types of Memory Unit(MU):

i)Primary Memory

    II)Secondary Memory

i)Primary Memory

Primary Memory is known as RAM (Random Access Memory), Temporary Memory. It’s called Temporary Memory because whenever Computers turn off, it lost all data.

RAM
Primary Memory

Its size disturbs working hours, Power, Speed of the Computer.

ii) Secondary Memory

Secondary Memory is famous as ROM (Read Only Memory).

Example of ROM :-

Hard Disc, DVD, CD, Pen Drive, Card  Reader, etc.

secondary memory

Different Useful Function of Memory Unit(MU)

  • It stores managed results of somewhat type of a calculation
  • Storage Unit stores all the required order and Data which necessary for processing
  • This Unit spread outputs and Inputs Data

2) ALU full form

ALU full form is Aerith Matic Unit. ALU controls all arithmetic and Logical works. It displays the vital structure block of the central processing unit. In modern CPUs contain powerful ALUs and Control Unit (CU).

 Sub Category of ALU

i)Arithmetic Part

ii)Logic Part

i)Arithmetic Part

Arithmetic Part performed all arithmetic works such as Subtraction, Division, Multiplication, Addition.

All complex operations and calculations are performed using the arithmetic functions.

ii)Logic Part

Logic Part performed all matching, paralleling, selecting, integration.

3) CU full form

CU full form Control Unit guides the action of the computer’s processor.

A CU delivery input information that it changes into a control signal which is sent to the CPU.

Control unit (CU) functions are:

  • It does not store the data.
  • It manages all parts of the Computer.
  • It interconnects with I/O devices of the computer for results from the Memory Unit(MU).

Types of Control Units (CU):

  1. Hardwired Control Unit
  2. Micro programmable Control Unit

Above we know CPU full form in computer, CPU definition, CPU diagram so let’s know the CPU components.
