Question

Draw a block diagram of a computer containing basic components of a computer. Explain the diagram.​

Answer 1

Answer:

Computer Block Diagram

Mainly computer system consists of three parts, that are central processing unit (CPU), Input Devices, and Output Devices. The Central Processing Unit (CPU) is divided into two parts again: arithmetic logic unit (ALU) and the control unit (CU). The set of instruction is in the form of raw data. Please mark me brainlist

Answer 2

Answer:

Explained below

Explanation:

A computer device is made up of various elements which help in its effective functioning and processing.

There are five basic components of the computer which help in making this processing of data easier and convenient.

components of a computer system are the primary elements which make the functioning of an electronic device smooth and faster. There are five basic components which include:

• Input Unit
• Output Unit
• Memory Unit
• Control Unit
• Arithmetical and Logical Unit

Input unit: computer will only respond when a command is given to the device. These commands can be given using the input unit or the input devices.

For example: Using a keyboard we can type things on a Notepad and the computer processes the entered data and then displays the output of the same of the screen.

Output Unit:When we command a computer to perform a task, it reverts for the action performed and gives us a result. This result is called output. There are various output devices connected to the computer. The most basic of which is a monitor. Whatever we write using a keyboard or click using a mouse, is all displayed on the monitor.

Thus, the output unit gives us the final result once the entire processing is done within the mechanism of a device.

Memory Unit: When we enter the data into the computer using an input device, the entered information immediately gets saved in the memory unit of the Central Processing Unit (CPU). Because of the presence of some existing programming, the Memory Unit transmits the data further to the other parts of the CPU.

Similarly, when the output of our command is processed by the computer, it is saved in the memory unit before giving the output to the user.

Arithmetic & Logical Unit: As the name suggests, all the mathematical calculations or arithmetic operations are performed in the Arithmetic and Logical Unit of the CPU.

It can also perform actions like a comparison of data and decision-making actions. The ALU comprises circuits using which addition, subtraction, multiplication, division and other numerical based calculations can be performed.

Central Processing Unit (CPU):

The Central Processing Unit is the core of any computer devices. It comprises three major components of the computer which have been discussed below

• Memory Unit
• Control Unit
• Arithmetic and Logical Unit

All these three units are elements of CPU and together help in the efficient working and processing of data. It is also known as the “Brain of Computer” and no action can be conducted by a device without the execution and permission of the Central Processing Unit.

The device is a close-knit circuit comparison microprocessor which helps in fetching the data and proving suitable results to the user. Thus, CPU is the main processing unit of the computer.
