ASCII reserves the first 32 code points (numbers 0–31 decimal) and the last one (number 127 decimal) for control characters. These are codes intended to control peripheral devices (such as printers), or to provide meta-information about data streams, such as those stored on magnetic tape. Despite their name, these code points do not represent ...
The delete control character (also called DEL or rubout) is the last character in the ASCII repertoire, with the code 127. [1] It is supposed to do nothing and was designed to erase incorrect characters on paper tape. It is denoted as ^? in caret notation and is U+007F in Unicode.

All entries in the ASCII table below code 32 10 (technically the C0 control code set) are of this kind, including CR and LF used to separate lines of text. The code 127 10 is also a control character. [1] [2] Extended ASCII sets defined by ISO 8859 added the codes 128 10 through 159 10 as control characters. This was primarily done so that if ...
The American Standard Code for Information Interchange (ASCII), uses a 7-bit binary code to represent text and other characters within computers, communications equipment, and other devices. Each letter or symbol is assigned a number from 0 to 127. For example, lowercase "a" is represented by 1100001 as a bit string (which is decimal 97).

Until the early 1990s, many programs and data transmission channels were character-oriented and treated some characters, e.g., ETX, as control characters.Others assumed a stream of seven-bit characters, with values between 0 and 127; for example, the ASCII standard used only seven bits per character, avoiding an 8-bit representation in order to save on data transmission costs.
Seven ASCII control characters map outside the upper-case alphabet: 0 is ^@, 27 is ^[, 28 is ^\, 29 is ^], 30 is ^^, 31 is ^_, and 127 is ^?. Examples are "^M^J" for the Windows CR, LF newline pair, and describing the ANSI escape sequence to clear the screen as "^[[3J".
