What is Computer Organisation and architecture

Hey friends today we have to understand what is Computer Organisation and architecture.
Before discussing Computer Organisation and architecture. it is necessary to some knowledge about computer.

So let be talked about what is computer computer definition in simple word and you easily understand ๐Ÿ™‚

Computer Organisation and architecture| what is computer

Understand computer || what is computer

ย 

The term computer orginates from the word โ€ computer โ€ย  it is Latin word. Whichย  means to calculate. computer normally considered as a calculating device which can perform an arithmetic operation at very fast speed but now it can be taken as an electronic device capable of receiving the input storage itโ€™s for a period of time processing it
A/C to set of instruction called program to providing the user and output in desired form.

ย 

Now understand Computer Organisation and architecture

ย 

A block diagram of basic Computer Organisation is show in figure

Work function of CPU in computer

ย 

Computer basically consists of three basic components

ย 

1. Input unit

ย 

2. Central Processing Unit (cpu)

ย 

CPU consists of mainly three parts

a. Arithmetic logic unit (ALU)

b. Memory unit (MU)

c. Control unit (CU)

And last

3. Output Unit

(What is Computer Organisation and architecture)

1. What is input unit

ย 

It is that past of computer through which user communicates with the computer. In other whatโ€™s input unit act as an interface between
User and computer for any type of computation to be performed performed through computer data / command / instruction must be entered to it.
This task is carried out by input unit.

The real information is entered the computer depends can the type of input device used example data can be entered through following input devices.

2. Understand CPU. what is central Processing Unit? ๐Ÿค”

This is main Processing Unit of computer it may be called brain of computer all the operation and data are performed by this unit is consists of three parts.

a. Arithmetic logic unit (AlU)

It performed two kinds of operationโ€™s

ย 

(What is Computer Organisation and architecture)

1.. arithmetic operation such as addition,subtraction, multiplication and division.

logic operation and comparison such as,less than equal to,or greater than.

The type of arithmetic of logical operation performed by a ALU depends on circuit designing of ALU, so performed and efficiency of ALU may vary from computer to computer in short ALU performs following functions.

aโ€ฆ It takes data from main memory.

ย 

b.. When it gets single from control unit CU it performs arithmetic or logic operations A/C to instruction.

ย 

cโ€ฆ It returns the final result to main memory from storage.

b. What is memory unit (MU)

ย 

The data instruction in turn into the computer system through input unit have to be a stored inside the computer before actual processing starts similarly the final result of the computation are also needed to be stored on to memory bhi for passing them to the output units.

ย 

# in simple word the storage component of computer is known as memory unit.

3. What is control unit (CU)

ย 

It is the nervous system of computer. control unit generates the electrical signals to control and co-ordinate The functioning of other unit it tells the input unit when to feed data into the memory.
It tells the output unit when to accept data from memory are supplied to users it also tells ALU when a what to be done with data.

ย 

4. And last point is what is output unit (OU)

ย 

The data of instruction in today by the input unit of processed by CPU after processing result must be supplied to the users this task is done by output unit this job of the output unit is reverse to that two input unit is give result to the outside world of it also links the computer with external environment.

ย 

It receive the process to result in binary forms and convert if to human understandable form.

(What is Computer Organisation and architecture)

Some example of output devices

-: visual display unit (VDU)
-: printer
-: plotters

Instruction set architecture of CPU registers

** what is an instruction set?

~> it is the collection of machine language instructions that a particular processor understands and executes.

Conclusion๐Ÿ‘Œ๐Ÿ’ฌ

In this article we provide notes on computer organisation and architecture.
In brief we get knowledge about what is computer, what is CPU, and CPU consists of, I hope this article help you to understand about computer organization and its work, plzz share this article infornt of ur friends and recommended other to taking eyes on this
