Network topology is the arrangement of the elements (links, nodes, etc.) of a communication network. [1] [2] Network topology can be used to define or describe the arrangement of various types of telecommunication networks, including command and control radio networks, [3] industrial fieldbusses and computer networks.
PSTN network topology is the switching network topology of a telephone network connected to the public switched telephone network (PSTN).. In the United States and Canada, the Bell System network topology was the switching system hierarchy implemented and operated from c. 1930 to the 1980s for the purpose of integrating the diverse array of local telephone companies and telephone numbering ...
Topology of a bus network. A bus network is a network topology in which nodes are directly connected to a common half-duplex link called a bus. [1] [2]A conceptual diagram of a local area network using bus topology
A three-dimensional model of a figure-eight knot.The figure-eight knot is a prime knot and has an Alexander–Briggs notation of 4 1.. Topology (from the Greek words τόπος, 'place, location', and λόγος, 'study') is the branch of mathematics concerned with the properties of a geometric object that are preserved under continuous deformations, such as stretching, twisting, crumpling ...
The circuit topology of an electronic circuit is the form taken by the network of interconnections of the circuit components. Different specific values or ratings of the components are regarded as being the same topology.
Natasha Jane Richardson was born in Marylebone, London on 11 May 1963, a member of the Redgrave family, known as a theatrical and film acting dynasty.She was the daughter of director and producer Tony Richardson and actress Vanessa Redgrave, [2] granddaughter of actors Sir Michael Redgrave and Rachel Kempson, [2] [3] sister of Joely Richardson, half-sister of Carlo Gabriel Nero and Katharine ...
The ARC/INFO Coverage data structure (1981), a topological data model based on POLYVRT. Topology was a very early concern for GIS. The earliest vector systems, such as the Canadian Geographic Information System, did not manage topological relationships, and problems such as sliver polygons proliferated, especially in operations such as vector overlay.

A graph with odd-crossing number 13 and pair-crossing number 15 [1]. In mathematics, a topological graph is a representation of a graph in the plane, where the vertices of the graph are represented by distinct points and the edges by Jordan arcs (connected pieces of Jordan curves) joining the corresponding pairs of points.
