Knowing how to use a computer is essential. Two of the most important input devices are the mouse and the keyboard. These tools allow us to communicate with the computer and perform different tasks. In this post, we will explore the functions of the mouse and keyboard, how they are used, and why they are important in ICT.
What is a Mouse?
A mouse is a small, hand-held device that helps users control the pointer on the computer screen. It allows you to click, drag, and select items.
Functions of the Mouse
- Pointing: Moves the cursor to select objects on the screen.
- Clicking: Selects files, folders, and links. A single click selects, while a double click opens items.
- Dragging: Allows you to move items from one place to another.
- Scrolling: The scroll wheel helps you move up and down on a page.
- Right-Clicking: Opens context menus with more options.
What is a Keyboard?
A keyboard is an input device with buttons called keys. These keys are used to type text, numbers, and give commands to the computer.
Functions of the Keyboard
- Typing: Used for writing letters, numbers, and symbols.
- Navigation: Arrow keys, Page Up, and Page Down help move around documents or web pages.
- Shortcuts: Key combinations like Ctrl + S to save or Ctrl + P to print help speed up tasks.
- Command Execution: Keys like Enter, Delete, and Esc are used to give instructions to the computer.
Why These Devices Are Important in ICT
Without the mouse and keyboard, it would be hard to interact with computers. They are essential for students, office workers, and anyone who uses a computer for work or study.
Understanding the roles of the mouse and keyboard helps students become more confident in using ICT tools. These input devices make it possible to control and give instructions to the computer efficiently.
