The most commonly encountered are the "XT" ("set 1") scancodes, based on the 83-key keyboard used by the IBM PC XT and earlier. These mostly consist of a single byte; the low 7 bits identify the key, and the most significant bit is clear for a key press or set for a key release. Some additional keys have an E0 (or rarely, E1 or E2) prefix.
The QR code system was invented in 1994, at the Denso Wave automotive products company, in Japan. [5] [6] [7] The initial alternating-square design presented by the team of researchers, headed by Masahiro Hara, was influenced by the black counters and the white counters played on a Go board; [8] the pattern of position detection was found and determined by applying the least-used ratio (1:1:3 ...
The OADG 109A and older 109 keyboard layouts which are the standard for Microsoft Windows have five dedicated language input keys: [ 1] halfwidth/fullwidth/kanji (hankaku/zenkaku/kanji 半角 / 全角 / 漢字) at the top left key of the keyboard; alphanumeric (eisū 英数 ), combined with non-language specific key ⇪ Caps Lock; non ...

The Fn key, short form for function, is a modifier key on many keyboards, especially external keyboards, and is not available for mobile devices. For use in a compact layout, combine keys which are normally kept separate. It-Alt + FN is typically found on laptops due to their keyboard size restrictions. It is also found on many full-sized ...
Mapcode. The mapcode system is an open-source geocode system consisting of two groups of letters and digits, separated by a dot. It represents a location on the surface of the Earth, within the context of a separately specified country or territory. For example, the entrance to the elevator of the Eiffel Tower in Paris is “France 4J.Q2”.
INT 16H. INT 16h, INT 0x16, INT 16H or INT 22 is shorthand for BIOS interrupt call 16hex, the 23rd interrupt vector in an x86-based computer system. The BIOS typically sets up a real mode interrupt handler at this vector that provides keyboard services. This interruption is responsible for control of the PC keyboard.
The code that is used for mapping of the keyboard scan matrix into the different physical layout keycap location. Keycode is different from scancode, the sequence of data generated when pressing or releasing a key on a computer keyboard, however, in legacy documents it may still refer to scancode . Keycode or may refer to: Keykode, an Eastman ...
