Computer - Components

All sorts of computer systems observe the same fundamental logical structure and carry out the subsequent five primary operations for converting raw enter facts into facts beneficial to their customers.

S.No. Operation Description

1 Take Input The process of getting into statistics and commands into the laptop gadget.

2 Store Data Saving records and instructions in order that they're to be had for processing as and when required.

3 Processing Data Performing mathematics, and logical operations on statistics to be able to convert them into useful records.

4 Output Information The technique of manufacturing useful records or effects for the user, including a printed document or visible display.

5 Control the workflow Directs the manner and sequence in which all of the above operations are finished.

 

Input Unit

This unit incorporates devices with the help of which we enter facts into the laptop. This unit creates a link among the user and the pc. The input gadgets translate the records into a form comprehensible by using the pc.

CPU (Central Processing Unit)

CPU is considered as the brain of the pc. CPU performs all varieties of statistics processing operations. It shops records, intermediate effects, and instructions (software). It controls the operation of all elements of the pc.

CPU itself has the subsequent 3 additives −

ALU (Arithmetic Logic Unit)

Memory Unit

Control Unit

Output Unit

The output unit consists of gadgets with the assist of which we get the information from the pc. This unit is a hyperlink between the laptop and the customers. Output gadgets translate the computer's output right into a shape understandable by using the customers. 

Computer - CPU(Central Processing Unit) 

Central Processing Unit (CPU) includes the subsequent functions −

CPU is taken into consideration because the mind of the pc.

CPU plays all forms of records processing operations.

It shops information, intermediate results, and instructions (application).

It controls the operation of all parts of the computer.

 

CPU itself has following 3 components.

Memory or Storage Unit

Control Unit

ALU(Arithmetic Logic Unit)

 

Memory or Storage Unit

This unit can shop commands, facts, and intermediate outcomes. This unit resources information to different units of the pc whilst needed. It is likewise referred to as internal garage unit or the principle memory or the primary storage or Random Access Memory (RAM).

Its size impacts pace, strength, and functionality. Primary memory and secondary memory are  varieties of reminiscences within the laptop. Functions of the memory unit are −

It shops all of the statistics and the instructions required for processing.

It shops intermediate consequences of processing.

It stores the final results of processing earlier than these effects are released to an output device.

All inputs and outputs are transmitted via the main reminiscence.

Control Unit

This unit controls the operations of all parts of the pc however does now not perform any actual statistics processing operations.

Functions of this unit are −

It is chargeable for controlling the switch of statistics and instructions among different gadgets of a computer.

It manages and coordinates all the gadgets of the computer.

It obtains the instructions from the reminiscence, interprets them, and directs the operation of the computer.

It communicates with Input/Output devices for transfer of facts or consequences from storage.

It does no longer manner or save data.

ALU (Arithmetic Logic Unit)

This unit includes  subsections namely,

Arithmetic Section

Logic Section

Arithmetic Section

Function of arithmetic phase is to perform arithmetic operations like addition, subtraction, multiplication, and department. All complex operations are performed by way of making repetitive use of the above operations.

Logic Section

Function of good judgment phase is to perform common sense operations along with comparing, deciding on, matching, and merging of information.
