In digitalcommunications, the simultaneous transmission of related signal elements over two or more separate paths.
Note: Protocols for parallel transmission, such as those used for computer ports, have been standardized by ANSI. Source: from Federal Standard 1037C and from MIL-STD-188 In communications, transmission is the act of transmitting electrical messages (and the associated phenonomena of radiant energy that pass through media). ... Signaling, or signal, may mean: Look up signal in Wiktionary, the free dictionary. ... A digital system is one that uses numbers for input, processing, transmission, storage, or display, rather than a continuous spectrum of values (an analog system) or non-numeric symbols such as letters or icons. ... The term communications is used in a number of disciplines: Communications, also known as communication studies is the academic discipline which studies communication. ... We usually define computer as a device or machine for processing information according to a program — a compiled list of instructions. ... Federal Standard 1037C entitled Telecommunications: Glossary of Telecommunication Terms is a U.S. Federal Standard, issued by the General Services Administration pursuant to the Federal Property and Administrative Services Act of 1949, as amended. ... MIL-STD-188 is a series of U.S. military standards relating to telecommunications. ...
In paralleltransmission, multiple bits (usually 8 bits or a byte/character) are sent simultaneously on different channels (wires, frequency channels) within the same cable, or radio path, and synchronized to a clock.
In telecommunication, serial transmission or sequential transmission is the sequential transmission of the signal elements of a group representing a character or other entity of data.
In computing, bit serial transmission is the transmission of several bits one after another, with all the bits transmitted over a single wire.
There are a number of equations you may encounter for determining the characteristic impedance of a paralleltransmission line, using the physical characteristics of the line as a basis.
There is some evidence that the greatest concentrations of electrons are on the facing surfaces of the parallel wires, with the consequence that losses may be larger for a given wire size in a transmission line than in other uses of similar wire.
Constructing an open wire transmission line is a balance of two factors: the optimal impedance for the line and the ease of construction.
