Components of Computer System | Computer Fundamental

All types of computers follow a  basic logical structure and follow some basic operations to convert raw data into useful information for the users.

1. Take Input

It is the process of getting the data and instructions from the user.

2. Store Data

Save data and Instructions for the future when we required.

3. Process Data

Perform the arithmetic and logical operations on data to convert it into useful information.

4. Output Information

It is the process of getting results from the computer system for the user.

5. Control the Workflow

Directs the manner and sequence in which all of the operations are performed.

Now we will describe all the units one by one

Components of Computer Hardware are:

•Input Unit

Input units are used to enter the data into a computer system. It creates a link between the user and the computer. The Input Units translate the information into computer-readable form.

CPU (Central Processing Unit)

CPU is known as the Brain of the Computer. CPU performs all types of data processing operations. It stores intermediate results, programs & data. Mainly CPU controls the operations of the computer's parts.

Components of CPU

1. ALU  (Arithmetic Logic Unit)

a) Arithmetic Section- It performs all the arithmetic operations like addition, subtraction, multiplication, and division.
b) Logic Section - It performs logical operations such as comparing, matching, selecting & merging data.

2. Memory Unit

Memory is used to store instructions, data & intermediate results. It sends the information to other units when required. Mainly memory unit is known as Internal,  Main & Primary memory, or RAM (Random Access Memory).

3. Control Unit 

It controls the operations of all parts of the computer but does not carry out any actual data processing.

•Output Unit

Output Units are used to get information from a computer system. It creates a link between the user and the computer. The Output Units translate the computer's data into human-readable form.
