Puuterisiveltimen

Puuterisiveltimen, also known as a computer mouse, is an input device used to control the cursor on a computer screen. It typically consists of a hand-held device with one or more buttons, and a sensor that tracks movement. The mouse is connected to the computer via a cable or wirelessly, and its primary function is to allow users to interact with graphical user interfaces (GUIs) by moving the cursor and selecting items.

The first computer mouse was invented by Douglas Engelbart in 1964. It was a wooden shell with two metal wheels that rolled on a grid of wires. Since then, mice have evolved significantly in terms of design, functionality, and technology. Modern mice come in various shapes, sizes, and styles, including optical, laser, and touchpad mice. They can also feature additional buttons, scroll wheels, and other specialized controls.

Computer mice are essential tools for navigating and manipulating digital content. They are used in a wide range of applications, from word processing and web browsing to gaming and graphic design. The mouse's design and functionality have been continually refined to improve user experience and efficiency, making it an indispensable component of modern computing.
