Payment card numbers are composed of 8 to 19 digits, [1] The leading six or eight digits are the issuer identification number (IIN) sometimes referred to as the bank identification number (BIN). [2]: 33 [3] The remaining numbers, except the last digit, are the individual account identification number. The last digit is the Luhn check digit.

The IBM 1400 series are character-addressable machines, each location being six bits labeled B, A, 8, 4, 2 and 1, plus an odd parity check bit (C) and a word mark bit (M). For encoding digits 1 through 9 , B and A are zero and the digit value represented by standard 4-bit BCD in bits 8 through 1 .
A binary file is a computer file that is not a text file. [1] The term "binary file" is often used as a term meaning "non-text file". [ 2 ] Many binary file formats contain parts that can be interpreted as text; for example, some computer document files containing formatted text , such as older Microsoft Word document files, contain the text of ...
In computer networks, location transparency is the use of names to identify network resources, rather than their actual location. [1] [2] For example, files are accessed by a unique file name, but the actual data is stored in physical sectors scattered around a disk in either the local computer or in a network. In a location transparency system ...
In a computer using virtual memory, accessing the location corresponding to a memory address may involve many levels. In computing, a memory address is a reference to a specific memory location in memory used by both software and hardware. [1] These addresses are fixed-length sequences of digits, typically displayed and handled as unsigned ...
The data files referred to by the cue sheet may be audio files (commonly in MP3 or WAV format), or plain disc images, usually with a .bin extension. When used for disc images, the format is usually called BIN/CUE, indicating that it stores a disc image composed of one cue sheet file and one or more .bin files.
In the table below, the column "ISO 8859-1" shows how the file signature appears when interpreted as text in the common ISO 8859-1 encoding, with unprintable characters represented as the control code abbreviation or symbol, or codepage 1252 character where available, or a box otherwise. In some cases the space character is shown as ␠.
