This document discusses computer networks and network topologies. It defines a computer network as a set of connected computers that share resources. The document outlines different types of computer networks and topologies, including personal area networks, local area networks, metropolitan area networks, wide area networks, bus, ring, star, mesh, tree, and hybrid topologies. Each topology refers to a different logical layout for how connected devices are arranged on a network.
