Core network components interconnect other network components. Gateway: an interface providing a compatibility between networks by converting transmission speeds, protocols, codes, or security measures. [2] Router: a networking device that forwards data packets between computer networks. Routers perform the "traffic directing" functions on the ...
A useful procedure in network analysis is to simplify the network by reducing the number of components. This can be done by replacing physical components with other notional components that have the same effect. A particular technique might directly reduce the number of components, for instance by combining impedances in series.

A network operating system (NOS) is a specialized operating system for a network device such as a router, switch or firewall.. Historically operating systems with networking capabilities were described as network operating systems, because they allowed personal computers (PCs) to participate in computer networks and shared file and printer access within a local area network (LAN).
In the seven-layer OSI model of computer networking, the physical layer or layer 1 is the first and lowest layer: the layer most closely associated with the physical connection between devices. The physical layer provides an electrical, mechanical, and procedural interface to the transmission medium.
Systems Network Architecture [1] (SNA) is IBM's proprietary networking architecture, created in 1974. [2] It is a complete protocol stack for interconnecting computers and their resources. SNA describes formats and protocols but, in itself, is not a piece of software.
In mathematics, computer science and network science, network theory is a part of graph theory. It defines networks as graphs where the vertices or edges possess attributes. Network theory analyses these networks over the symmetric relations or asymmetric relations between their (discrete) components.
[1] BNU was written by David Nugent as an experimental driver for serial communications following the FOSSIL specification. [2] David released BNU to the public in 1989 and its use in the BBS world spread rapidly. BNU was one of only two or three available FOSSIL drivers for the IBM PC compatible hardware and MS-DOS/PC DOS operating system.
