A bit that (a) is successfully transferred to a destination user, (b) performs its primary function within the telecommunications system, and (c) does not represent user information.
Industry:Telecommunications
A bit string that is a function of both data (either plaintext or ciphertext) and a secret key, and that is attached to the data in order to allow data authentication. Note: The function used to generate the message authentication code must be a one-way function. 2. Data associated with an authenticated message allowing a receiver to verify the integrity of the message.
Industry:Telecommunications
A bit intentionally written on a diskette with a weak magnetic field strength that may be interpreted as zero or one and that is written as part of a method of copy protection.
Industry:Telecommunications
A bit in a signal unit which indicates the start of a retransmission cycle.
Industry:Telecommunications
A bit delivered to the intended destination user in addition to intended user information bits and delivered overhead bits. Synonym extra bit.
Industry:Telecommunications
A binary code in which consecutive decimal numbers are represented by binary expressions that differ in the state of one, and only one, one bit. Synonym reflected code.
Industry:Telecommunications
A binary-coded decimal notation in which (a) each decimal digit is represented by a binary numeral consisting of five binary digits of which two are of one kind, called "ones," and three are of the other kind, called "zeros" and (b) the usual weights assigned to the digit positions are 0-1-2-3-6, except that "zero" is represented as 01100.
Industry:Telecommunications
A binary notation in which each of the decimal digits is represented by a binary numeral. Synonyms binary-coded decimal code, binary-coded decimal representation.
Industry:Telecommunications
A binary encoding scheme in which a signal parameter, such as electric current or voltage, undergoes a change in a significant condition or level every time that a "zero" occurs, but when a "one" occurs, it remains the same, i.e., no transition occurs. Note 1: The transitions could also occur only when "ones" occur and not when "zeros" occur. If the significant condition transition occurs on each "one," the encoding scheme is called "non-return to zero mark" (NRZ-M. ) Note 2: NRZ-S and NRZ-M signals are technically interchangeable; i.e., one is the logical "NOT" (inverse) of the other. It is necessary for the receiver to have prior knowledge of which scheme is being used. Without such knowledge, it is impossible for the receiver to interpret the data stream correctly; i.e., its output may be the correct data stream or the logical inverse of the correct data stream. Synonym non-return-to-zero.
