Parallel communication is and always has been widely used within integrated circuits, in peripheral buses, and in memory devices such as RAM. Computer system buses, on the other hand, have evolved over time: parallel communication was commonly used in earlier system buses, whereas serial communications are prevalent in modern computers.
In computing, a parallel port is a type of interface found on early computers (personal and otherwise) for connecting peripherals. The name refers to the way the data is sent; parallel ports send multiple bits of data at once (parallel communication), as opposed to serial communication, in which bits are sent one at a
The DLX (pronounced "Deluxe") is a RISC processor architecture designed by John L. Hennessy and David A. Patterson, the principal designers of the Stanford MIPS and the Berkeley RISC designs (respectively), the two benchmark examples of RISC design (named after the Berkeley design).
John Leroy Hennessy (born September 22, 1952) is an American computer scientist who is chairman of Alphabet Inc. (Google). [8] Hennessy is one of the founders of MIPS Technologies and Atheros, and also the tenth President of Stanford University. Hennessy announced that he would step down in the summer of 2016.
A cabinet from IBM's Blue Gene/L massively parallel supercomputer. A massively parallel processor (MPP) is a single computer with many networked processors. MPPs have many of the same characteristics as clusters, but MPPs have specialized interconnect networks (whereas clusters use commodity hardware for networking).
An IEEE 1284 36-pin female on a circuit board. In the 1970s, Centronics developed the now-familiar printer parallel port that soon became a de facto standard.Centronics had introduced the first successful low-cost seven-wire print head [citation needed], which used a series of solenoids to pull the individual metal pins to strike a ribbon and the paper.
IBM licensed the architecture to other companies for one to five percent of revenue. [13] Tandy Corporation was the first to ship a Micro Channel-based computer, the 5000 MC, but company head John Roach said "I'm surprised anybody at all would want it"; Tandy only sold the computer, he said, because there was some demand for it.

Xpress links can only be used in systems that have 16 or 32 processors, as these are the only configurations with a network topology that enables unused ports to be used in such a way. The architecture has its roots in the DASH project at Stanford University, led by John L. Hennessy, which included two of the Origin designers. [8] [9]
