ASCII (/ ˈ æ s k iː / ⓘ ASS-kee), [3]: 6 an acronym for American Standard Code for Information Interchange, is a character encoding standard for electronic communication. ASCII codes represent text in computers, telecommunications equipment, and other devices.
In other words, it does not matter whether the key would have produced an upper-case or a lower-case letter. The interpretation of the control key with the space, graphics character, and digit keys (ASCII codes 32 to 63) varies between systems. Some will produce the same character code as if the control key were not held down.
Shift In and Shift Out used in a Linux terminal to access a variant DEC Special Graphics set. Shift Out (SO) and Shift In (SI) are ASCII control characters 14 and 15, respectively (0x0E and 0x0F). [1]
Punched tape with the word "Wikipedia" encoded in ASCII.Presence and absence of a hole represents 1 and 0, respectively; for example, W is encoded as 1010111.. Character encoding is the process of assigning numbers to graphical characters, especially the written characters of human language, allowing them to be stored, transmitted, and transformed using computers. [1]
It does not assign normative names to these control codes, though it does assign them normative aliases. [ 1 ] Category "Cc" control codes can serve a variety of purposes, not limited to format effectors: for example, the default ASCII C0 set includes six format effectors ( BS , HT , LF , VT , FF and CR ), ten transmission controls, four device ...
Box-drawing characters therefore typically only work well with monospaced fonts. In graphical user interfaces , these characters are much less useful as it is more simple and appropriate to draw lines and rectangles directly with graphical APIs .
Strictly speaking, text-based means employing an encoding system of characters designed to be printable as text data. [1]: 54 As most computers only read binary code, encoding formats are typically written in such, where a bit is the smallest unit of data that has two possible values and each combination of bits represents a byte.
ASCII does not have the much greater-than sign. The double greater-than sign is also used for an approximation of the closing guillemet, ». In Java, C, and C++, the operator >> is the right-shift operator. In C++ it is also used to get input from a stream, similar to the C functions getchar and fgets. In Haskell, the >> function is a monadic ...
