Mouse: A Handheld Input Device
Definition of a Mouse
A computer mouse, also known as a pointing device or a trackball, is a hardware input device used to control the cursor in a graphical user interface (GUI). It allows users to point, move, and select items on the screen with ease.
How a Mouse Works
A mouse typically consists of two or more buttons, a scroll wheel, and a sensor that detects movement. When the mouse is moved, the sensor tracks the movement and transmits data to the computer, which then translates it into on-screen movements of the cursor.
Types of Mice
- Wired Mice: Connect to the computer via a USB cable.
- Wireless Mice: Use wireless technology, such as Bluetooth or RF, to connect to the computer.
- Gaming Mice: Designed specifically for gaming with advanced features like programmable buttons and adjustable sensitivity.
- Trackball Mice: Feature a stationary ball on the top that is moved to control the cursor.
Uses of a Mouse
Mice are essential for navigating and interacting with a computer interface. They are used for tasks such as:
- Controlling the cursor and selecting items
- Dragging and dropping files
- Scrolling through documents and web pages
- Performing specific actions, such as clicking and double-clicking
