Key rollover is the ability of a computer keyboard to correctly handle several simultaneous keystrokes. A keyboard with n-key rollover (NKRO) can correctly detect input from each key on the keyboard at the same time, regardless of how many other keys are also being pressed. Keyboards that lack full rollover will register an incorrect keystroke ...
A keyboard buffer is a section of computer memory used to hold keystrokes before they are processed. [1]Keyboard buffers have long been used in command-line processing. As a user enters a command, they see it echoed on their terminal and can edit it before it is processed by the computer.
A gaming keypad is a small, auxiliary keyboard designed only for gaming. It has a limited number of the original keys from a standard keyboard, and they are arranged in a more ergonomic fashion to facilitate quick and efficient gaming key presses. The commonly used keys for gaming on a computer are the 'W', 'A', 'S', 'D', and the keys close and ...
Keystroke logging, often referred to as keylogging or keyboard capturing, is the action of recording (logging) the keys struck on a keyboard, [1] [2] typically covertly, so that a person using the keyboard is unaware that their actions are being monitored. Data can then be retrieved by the person operating the logging program.
An additional 4 MB of Fast RAM can be added in the PC Card slot using a suitable SRAM card to reach a capacity of 6 MB. However, additional Fast RAM can be added with unofficial memory or CPU upgrades. For example, the A608 [18] board adds up to a maximum of 8 MB additional RAM by connecting over the original 68000. Likewise, CPU upgrades can ...
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.
