Input devices are devices used to collect information from users or external sources and send it to the computer for processing. These devices can be broadly divided into two categories: mice and keyboards.
Mouses are multi-functional input devices that offer a variety of functionalities. They usually consist of a ball that can be moved across a surface, along with buttons for specific actions. Some mice even have trackballs that move along a circular track, providing a more natural writing experience.
Keyboards, on the other hand, are designed for single-key input. They consist of a set of keys arranged in a specific order, with each key representing a specific letter, number, or symbol. Pressing a key corresponds to pressing the corresponding key on the keyboard.
Here are some key functions of each type of device:
Mouse:
Pointing and clicking: Used to move the cursor on the screen and select objects.
Scrolling: Used to navigate through web pages and documents.
Right-clicking: Used to access context menu options and perform advanced actions.
Scroll wheel: Used to zoom in or out of documents.
Keyboard:
Typewriting: Used to input letters, words, and sentences.
Editing: Used to select, copy, and delete text.
Navigation: Used to move around a document or window.
Entering special characters: Used to insert symbols and punctuation.
By understanding the types and functions of input devices, you can effectively use them to interact with your computer and complete various tasks
