what is a computer ?

A computer is an electronic device that can process, store, retrieve, and transmit data. It can perform various tasks and instructions based on the software installed in it. The computer consists of hardware components like the central processing unit (CPU), memory, hard drive, monitor, keyboard, and mouse and software components like operating system, applications, and programs. The computer has revolutionized the way we work, learn, communicate, and entertain ourselves, making our lives more convenient and productive.

The basic parts without which a computer cannot work are.

1)  Central Processing Unit (CPU): It is the brain of the computer that performs all the calculations and instructions

2)  Random Access Memory (RAM): It is a temporary memory that stores the data and instructions for the CPU to access quickly.

3) Storage: It is a device that stores data permanently, such as a hard drive or solid-state drive.

4) Motherboard: It is the main circuit board that connects all the components of the computer.

5) Power Supply Unit (PSU): It provides power to all the components in the computer.

6)  Graphics Processing Unit (GPU): It is responsible for the display of images and videos on the computer monitor

7)  Input and Output Devices: These include a keyboard, mouse, monitor, and speakers that allow users to input data and receive output from the computer

.All these components need to work together to ensure the proper functioning of a computer.
