Foreword
ISO (the International Organization for Standardization) and IEC (the International Electrotechnical
Commission) form the specialized system for worldwide standardization. National bodies that are
members of ISO or IEC participate in the development of International Standards through technical
committees established by the respective organization to deal with particular fields of technical activity.
ISO and IEC technical committees collaborate in fields of mutual interest. Other international organizations,
governmental and non-governmental, in liaison with ISO and IEC, also take part in the work.
The procedures used to develop this document and those intended for its further maintenance are described
in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the different types
of document should be noted. This document was drafted in accordance with the editorial rules of the ISO/
IEC Directives, Part 2 (www.iso.org/directives or www.iec.ch/members_experts/refdocs).
ISO and IEC draw attention to the possibility that the implementation of this document may involve the
use of (a) patent(s). ISO and IEC take no position concerning the evidence, validity or applicability of any
claimed patent rights in respect thereof. As of the date of publication of this document, ISO and IEC had not
received notice of (a) patent(s) which may be required to implement this document. However, implementers
are cautioned that this may not represent the latest information, which may be obtained from the patent
database available at www.iso.org/patents and https://patents.iec.ch. ISO and IEC shall not be held
responsible for identifying any or all such patent rights.
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and expressions
related to conformity assessment, as well as information about ISO's adherence to the World Trade
Organization (WTO) principles in the Technical Barriers to Trade (TBT) see www.iso.org/iso/foreword.html.

This document was prepared by Joint Technical Committee ISO/IEC JTC 1, Information technology,
Subcommittee SC 31, Automatic identification and data capture techniques.
This second edition cancels and replaces the first edition of ISO/IEC 19762:2016, which has been technically
revised.
The main changes are as follows:
— French, Russian, Germany and Korean terms have been deleted;
— outdated terms have been deleted;
— the sources in terminological entries have been updated;
— the abbreviated terms have been updated and moved to Annex A.
Any feedback or questions on this document should be directed to the user’s national standards
body. A complete listing of these bodies can be found at www.iso.org/members.html and

3.1 Terms related to general concepts
3.1.1 Basic general concepts
3.1.1.1
bit
binary digit
either of the digits 0 or 1 when used in the binary numeration system
3.1.1.2
information bit
bit (3.1.1.1) used for the representation of user data, rather than for control purposes
3.1.1.3
least significant bit
LSB
bit (3.1.1.1) position having the smallest weight used in positional notation
3.1.1.4
most significant bit
MSB
bit (3.1.1.1) position having the largest weight used in positional notation
3.1.1.5
byte
string that consists of a number of bits (3.1.1.1), treated as a unit, and usually representing a character or a
part of a character
Note 1 to entry: The number of bits in a byte is fixed for a given data processing system.
Note 2 to entry: The number of bits in a byte is usually 8.
© ISO/IEC 2025 – All rights reserved
Note 3 to entry: A byte is often eight logical data bits, but can include error detection or correction bits.
Note 4 to entry: 8 bits of data designated b1 to b8, from the most significant bit (MSB, b8) (3.1.1.4) to the least significant
bit (LSB, b1) (3.1.1.3).
3.1.1.6
hexadecimal,noun
Hex
representative data to base 16, using the numbers 0 to 9 and the letters A to F
Note 1 to entry: Used as a convenient short hand notation for representing 16 and 32 bit memory addresses.
Note 2 to entry: A popular method of representing hexadecimal is in the form 0xNN, where NN is the hexadecimal value.
EXAMPLE The number 10 is represented in hexadecimal as 'A'.
3.1.1.7
hexadecimal,adj.
characterized by a selection choice, or condition that has sixteen possible different values or states
3.1.1.8
character
member of a set of elements used by agreement, for the organization, representation or control of information
Note 1 to entry: Characters can be letters, digits, punctuation marks or other symbols and, by extension, function
controls such as space shift, carriage return or line feed contained in a message.
[SOURCE: IEC 60050-702:1992, 702-05-10]
3.1.1.9
data character
character (3.1.1.8) which represents meaningful information
Note 1 to entry: Data characters may be numeric digits, alphabetic characters, punctuation marks or control
characters.
3.1.1.10
character set
finite set of characters that is complete for a given purpose
Note 1 to entry: The international reference version of the character set is ISO/IEC 10646.
3.1.1.11
code
collection of rules that maps the elements of a first set onto the elements of a second set
Note 1 to entry: The elements of either set may be characters or character strings.
Note 2 to entry: The first set is called coded set and the second set is called code set.
Note 3 to entry: Each element of the code set may be related to more than one element of the coded set but the reverse
is not true.
3.1.1.12
code element
code value
result of applying a code to an element of a coded set
EXAMPLE "CDG" representing Paris Charles-de-Gaulle in the code for three-letter representation of airport
names; the hexadecimal number 0041 representing "Latin capital letter A" in ISO/IEC 10646.
