The Mouse
In computing, a mouse is an input device that functions by detecting two-dimensional motion relative to its supporting surface.
1. The idea for the computer mouse came to Engelbart in 1961 at a conference, while thinking about how to make graphical computer interfaces more efficient.
2. The first mouse prototype was made out of wood, a circuit board, and two metal wheels that did not come into contact with the surface it was on.
3. Engelbart would go on to refine this prototype in 1972, when he created the ball mouse that was the standard type of computer mouse until 1998.
The Keyboard
In computing, a keyboard is a typewriter-style device, which uses an arrangement of buttons or keys, to act as mechanical levers or electronic switches.
1. The qwerty layout was designed for manual typewriters initially by Christopher Sholes all the way back in 1872.
2. Most modern keyboards use the "qwerty" layout. This name comes from the first five letters on the top row.
3. The word typewriter can be typed entirely using the top row of keys. It has been speculated that this may have been a factor in the choice of keys for ease of demonstration.
The Windows
In computing, a window is a visual area containing some kind of user interface, the window decoration. It usually has a rectangular shape that can overlap with the area of other windows. It displays the output of and may allow input to one or more processes.
1. Microsoft Windows is a series of graphical interface operating systems developed, marketed, and sold by Microsoft.
2. Microsoft introduced an operating environment named Windows on November 20, 1985 as a graphical operating system shell for MS-DOS in response to the growing interest in graphical user interfaces (GUI).
3. As of October 2013, the most recent versions of Windows for personal computers, mobile devices, server computers and embedded devices are respectively Windows 8.1,
