Windows keyboards worldwide tend to simply label the key with the text ↵ Enter, while Apple uses the symbol ⌤ (U+2324 ⌤ UP ARROWHEAD BETWEEN TWO HORIZONTAL BARS [9] or U+2305 ⌅ PROJECTIVE) on ISO and JIS keyboards and the text ⌅ enter on ANSI US keyboards; [10] this is acknowledged by an annotation "enter key" on U+2324 in the Unicode ...
For the user to get the benefit of the full n-key rollover, the complete key press status must be transmitted to the computer. When the data is sent via the USB protocol, there are two operating modes: Human Interface Device (HID) "report protocol" and "boot protocol". The (optional) boot protocol, which is solely used by very limited USB host ...
Functional layout is the arrangement of the key-meaning association or keyboard mapping, determined in software, of all the keys of a keyboard; it is this (rather than the legends) that determines the actual response to a key press. Modern computer keyboards are designed to send a scancode to the operating system (OS) when a key is pressed or ...
An interrupt (also known as an abort, exception, fault, signal, [52] or trap) [53] provides an efficient way for most operating systems to react to the environment. Interrupts cause the central processing unit (CPU) to have a control flow change away from the currently running program to an interrupt handler , also known as an interrupt service ...
The Jensen box is an example of an instrument designed to measure choice RT with visual stimuli and keypress response. [49] Response criteria can also be in the form of vocalizations, such as the original version of the Stroop task , where participants are instructed to read the names of words printed in colored ink from lists.

Flowchart of using successive subtractions to find the greatest common divisor of number r and s. In mathematics and computer science, an algorithm (/ ˈ æ l ɡ ə r ɪ ð əm / ⓘ) is a finite sequence of mathematically rigorous instructions, typically used to solve a class of specific problems or to perform a computation.
