Keyboard

A computer keyboard is an input device used to enter characters and functions into the computer system by pressing buttons, or keys. It is the primary device used to enter text. A keyboard is connected to a computer system using a cable or a wireless connection. Typical keyboard for a desktop computer typical keyboard Most keyboards have a very similar layout. The function keys typically perform a very specific task within a particular software application.

However, this general layout has remained remarkably unchanging over the years. This has made it easy for users to transition from one computer system to the next and to use their typing skills on multiple devices.

For many tasks, you need to press more than one key at the same time. For example, to get a capital letter ‘A,’ you need to press the Shift key and the A key at the same time. When reading or writing instructions for how to accomplish a particular task, this would be described as ‘Shift + A.’ As another example, in most software applications, Ctrl + S means to save the current document. If you have been using computers for some time, you are probably.

Mouse

A computer mouse (plural mice, sometimes mouses)[nb 1] is a hand-held pointing device that detects two-dimensional motion relative to a surface. The first public demonstration of a mouse controlling a computer system was in 1968. Mice originally used two separate wheels to track movement across a surface; one in the X-dimension and one in the Y. Later, the standard design shifted to utilize a ball rolling on a surface to detect motion. Most modern mice use optical sensors that have no moving parts. Though originally all mice were connected to a computer by a cable, some modern mice are cordless, relying on short-range radio communication with the connected system.

In addition to moving a cursor, computer mice have one or more buttons to allow operations such as the selection of a menu item on a display. Mice often also feature other elements, such as touch surfaces and scroll wheels, which enable additional control and dimensional input.
