Answer to Question #270586 in Computer Networks for foqi

Question

Describe the nature of the network by explicitly indicating what kind of objects are its

nodes and their number, what kind of relation the links represent and their number, and what actual

function does the network represent.

Answer 1

A computer network is a set of computers sharing resources located on or provided by network nodes.

In data communications, physical network nodes include data communications equipment or devices that sit between data terminal equipment (DTE) and data transmission circuits. These include switches, bridges, modems or hubs that perform signal conversion, coding and line clocking. The computers use common communication protocols over digital interconnections to communicate with each other. These interconnections are made up of telecommunication network technologies, based on physically wired, optical, and wireless radio-frequency methods that may be arranged in a variety of network topologies.
