1. Moving the cursor: The most basic function of a mouse is to move the cursor on the screen. As you move the mouse, the cursor moves in a corresponding direction, allowing you to point to and interact with different elements on the screen.


2. Clicking: Clicking the mouse buttons is used to select items, activate buttons, and open menus. There are typically two buttons on a mouse: a left button and a right button. The left button is used for most common actions, while the right button often brings up context-sensitive menus that provide additional options.


3. Dragging: Dragging allows you to move items around on the screen. To drag an item, you click on it and hold the button down while you move the mouse. When you release the button, the item will be moved to the new location.


4. Scrolling: Many mice have a scroll wheel that allows you to scroll up and down through documents, web pages, and other content. You can also use the scroll wheel to zoom in and out of images and documents.


5. Additional functions: Some mice have additional buttons or features that provide even more functionality. For example, some mice have programmable buttons that can be assigned to specific tasks, while others have touchpads that allow you to use gestures to control the cursor.

These are just some of the basic functions of a computer mouse. With its intuitive design and versatility, the mouse has become an essential tool for anyone who uses a computer.
