QWERTY(keyboard layout)

Qwerty is the most popular keyboard layout that in use today. This layout was named QWERTY because these six letters are appearing in the top layer of the keyboard.
The QWERTY keyboard design was created by Christopher Latham Sholes in 1873 at Milwaukee, Wisconsin.

Wisconsin Historical Marker
The first computer terminals such as the Teletype were typewriters that could produce and be controlled by various computer codes. These used the QWERTY layouts, and added keys such as escape (ESC) which had special meanings to computers. Later keyboards added function keys and arrow keys. Since the standardization of PC-compatible computers and Windows after the 1980s, most full-sized computer keyboards have followed this standard (see drawing at right). This layout has a separate numeric keypad for data entry at the right, 12 function keys across the top, and a cursor section to the right and center with keys for Insert, Delete, Home, End, Page Up, and Page Down with cursor arrows in an inverted-T shape.
