Most of the communication primitives presented in this article share a common template. [2] Initially, each processing element possesses one message that must reach every other processing element during the course of the algorithm. The following pseudo code sketches the communication steps necessary.
Paul Baran (born Pesach Baran / ˈ b æ r ən /; April 29, 1926 – March 26, 2011) was an American-Jewish engineer who was a pioneer in the development of computer networks.He was one of the two independent inventors of packet switching, which is today the dominant basis for data communications in computer networks worldwide, and went on to start several companies and develop other ...
The law is, in a strict sense, only about correspondence; it does not state that communication structure is the cause of system structure, merely describes the connection. Different commentators have taken various positions on the direction of causality; that technical design causes the organization to restructure to fit, [ 10 ] that the ...
The earliest ideas for a computer network intended to allow general communications among computer users were formulated by computer scientist J. C. R. Licklider of Bolt Beranek and Newman (BBN), in April 1963, in memoranda discussing the concept of the "Intergalactic Computer Network". Those ideas encompassed many of the features of the ...
An internetwork is the connection of multiple different types of computer networks to form a single computer network using higher-layer network protocols and connecting them together using routers. The Internet is the largest example of internetwork. It is a global system of interconnected governmental, academic, corporate, public, and private ...
Network architecture is the design of a computer network.It is a framework for the specification of a network's physical components and their functional organization and configuration, its operational principles and procedures, as well as communication protocols used.
The effort invested in development of libraries of high-level grid and communication primitives greatly eased the effort of moving applications to the computer, and also provides substantial high-level portability to other systems, since the communication library could be implemented in terms of low level primitives on any distributed system.

Unlike device communications, where the form of the message data is limited to protocols supported by the type and capabilities of the devices involved (for example in computer networking we have the TCP and UDP protocols, a walkie-talkie would sending radio waves in specific frequency, and a beacon would be flashing Morse code sequences that a ...
