What is the primary function of a mouse in computer operations?

The primary function of a mouse in computer operations is to control the cursor on the screen. This essential input device allows users to interact with the graphical user interface (GUI) of their computer. By moving the mouse across a flat surface, the user can navigate the cursor, enabling them to select icons, open applications, and manipulate screen elements with precision. The mouse typically features buttons and sometimes a scroll wheel, which further enhance its functionality by allowing users to perform various actions such as clicking and scrolling. Thus, the ability of the mouse to manipulate the cursor is fundamental to effective computer use, making it a critical tool for users when performing tasks on their devices.
