Content:

What Are Input Devices?

• Input devices are tools or equipment used to send data or commands into a computer.
• They help users interact with the computer by providing instructions or information for processing.

Examples of Input Devices:

1. Keyboard: Used for typing letters, numbers, and symbols into the computer.
2. Mouse: Used to point, click, and select items on the computer screen.
3. Scanner: Converts physical documents or images into digital formats for the computer.
4. Microphone: Captures voice or sound for the computer.
5. Joystick: Used for playing games by controlling movements.

Functions of Input Devices:

1. Data Entry: Input devices like keyboards and scanners allow users to enter data into the computer.
2. Control: Devices like the mouse and joystick help users control actions on the computer screen.
3. Communication: Microphones help users record their voice or communicate during video calls.
4. Instruction Sending: Input devices send commands that tell the computer what to do.

Importance of Input Devices:

• Input devices allow users to interact with the computer.
• Without input devices, it would be impossible to give instructions or enter data.
