Parallel resistance is illustrated by the circulatory system. Each organ is supplied by an artery that branches off the aorta. The total resistance of this parallel arrangement is expressed by the following equation: 1/R total = 1/R a + 1/R b + ... + 1/R n. R a, R b, and R n are the resistances of the renal, hepatic, and other arteries ...
Parallel versus serial communication In data transmission , parallel communication is a method of conveying multiple binary digits ( bits ) simultaneously using multiple conductors. This contrasts with serial communication , which conveys only a single bit at a time; this distinction is one way of characterizing a communications link .

[10] [11] Dataproducts parallel was available in a short-line for connections up to 50 feet (15 m) and a long-line version using differential signaling for connections to 500 feet (150 m). The Dataproducts interface was found on many mainframe systems up through the 1990s, and many printer manufacturers offered the Dataproducts interface as an ...
Series and parallel topologies can continue to be constructed with greater and greater numbers of branches ad infinitum. The number of unique topologies that can be obtained from n ∈ N {\displaystyle n\in \mathbb {N} } series or parallel branches is 1, 2, 4, 10, 24, 66, 180, 522, 1532, 4624, … {\displaystyle \dots } (sequence A000084 in the ...
An IEEE 1284 36-pin male micro ribbon printer cable connection. The computer side normally uses a DB-25 port instead of this connector. IEEE 1284, also known as the Centronics port, is a standard that defines bi-directional parallel communications between computers and other devices.
A parallel optical interface is a form of fiber-optic technology aimed primarily at communications and networking over relatively short distances (less than 300 meters), and at high bandwidths. Parallel optic interfaces differ from traditional fiber-optic communication in that data is simultaneously transmitted and received over multiple fibers.
Figure 1: Example two-port network with symbol definitions. Notice the port condition is satisfied: the same current flows into each port as leaves that port.. In electronics, a two-port network (a kind of four-terminal network or quadripole) is an electrical network (i.e. a circuit) or device with two pairs of terminals to connect to external circuits.
