An input device is a device that users interact with to provide instructions or data to a computer. These devices allow users to perform various tasks, such as typing, clicking, selecting, and more.
There are two main types of input devices: keyboard and mouse.
Keyboard:
A keyboard is a mechanical device with keys that users press to type letters, numbers, and symbols.
Each key has a specific function, and pressing them in the correct order forms a word or sentence.
Examples: QWERTY keyboard, Dvorak keyboard, etc.
Mouse:
A mouse is a pointing device with a ball and a clicking mechanism.
Users place the mouse on the computer screen and move it to click on icons, buttons, and other objects.
Mice come in various shapes and sizes, and their functionalities can vary depending on the brand.
Functions of input devices:
Keyboard:
Provides a limited set of keys for specific tasks.
Used for typing, entering text, and performing simple calculations.
Mouse:
Provides greater freedom of movement and manipulation.
Allows users to point and click on objects, icons, and menus.

Additional notes:
Input devices can be classified into more specific categories based on their functionality. For example, a keyboard can be considered a pointing device, while a mouse is primarily a keyboard with an additional pointing function.
Some devices can act as both a keyboard and a mouse simultaneously. For instance, laptops and tablets often use touchscreens as input devices
