Diagram Of Parts Of Computer

A computer can process data, pictures, sound and graphics. They tin can solve highly complicated problems speedily and accurately. A computer as shown in Fig. performs basically 5 major computer operations or functions irrespective of their size and make. These are

1) information technology accepts data or instructions by way of input,
two) it stores data,
3) it can process information equally required past the user,
4) it gives results in the class of output, and
5) it controls all operations inside a computer.

We hash out below each of these Computer operation

Block Diagram of Computer and Explain its Various Components

1. Input: This is the process of entering data and programs in to the computer system. You should know that computer is an electronic automobile similar any other machine which takes as inputs raw data and performs some processing giving out processed data. Therefore, the input unit takes data from united states to the figurer in an organized manner for processing.

ii. Storage: The process of saving information and instructions permanently is known as storage. Information has to be fed into the system before the actual processing starts. Information technology is because the processing speed of Central Processing Unit (CPU) is so fast that the data has to be provided to CPU with the aforementioned speed. Therefore the data is get-go stored in the storage unit for faster access and processing. This storage unit or the main storage of the computer organisation is designed to practise the above functionality. It provides space for storing data and instructions.

The storage unit of measurement performs the post-obit major functions:

• All information and instructions are stored here before and after processing.

• Intermediate results of processing are also stored hither.

3. Processing: The task of performing operations like arithmetic and logical operations is called processing. The Central Processing Unit (CPU) takes data and instructions from the storage unit and makes all sorts of calculations based on the instructions given and the blazon of data provided. Information technology is then sent dorsum to the storage unit.

4. Output: This is the procedure of producing results from the data for getting useful information. Similarly the output produced by the computer after processing must also exist kept somewhere within the figurer before being given to you lot in homo readable grade. Once again the output is also stored within the calculator for further processing.

five. Control: The mode how instructions are executed and the above operations are performed. Decision-making of all operations like input, processing and output are performed past command unit. It takes care of step past step processing of all operations inside the computer.

Functional Units

In order to carry out the operations mentioned in the previous section the calculator allocates the job betwixt its various functional units. The computer system is divided into three divide units for its operation. They are

Arithmetic Logical Unit (ALU)

Logical Unit :After you enter data through the input device information technology is stored in the main storage unit. The bodily processing of the data and instruction are performed by Arithmetics Logical Unit. The major operations performed past the ALU are add-on, subtraction, multiplication, division, logic and comparison. Data is transferred to ALU from storage unit when required. Subsequently processing the output is returned back to storage unit for farther processing or getting stored.

Control Unit (CU)

The adjacent component of computer is the Control Unit, which acts similar the supervisor seeing that things are done in proper fashion. Control Unit is responsible for coordinating diverse operations using time signal. The control unit of measurement determines the sequence in which computer programs and instructions are executed. Things like processing of programs stored in the main memory, interpretation of the instructions and issuing of signals for other units of the computer to execute them. It also acts as a switch board operator when several users admission the computer simultaneously. Thereby information technology coordinates the activities of figurer'southward peripheral equipment equally they perform the input and output.

Central Processing Unit (CPU)

The ALU and the CU of a computer system are jointly known as the cardinal processing unit. You may phone call CPU as the brain of whatsoever reckoner arrangement. Information technology is simply like brain that takes all major decisions, makes all sorts of calculations and directs different parts of the computer functions by activating and decision-making the operations.
