What are the various network topologies (layouts), and why is network topology important in planning a network?
In a bus topology, all nodes are connected to a single linear cable. Ring topologies are comprised of nodes arranged roughly in a circle in which the data flows from node to node in a specific order. In a star topology, nodes are connected to a central communication device (a switch) and branch out like points of a star. A hybrid topology is a blending of other types of topologies in one network. Each topology has its own advantages and disadvantages. Topology selection depends mainly on two factors: (1) the network budget and (2) the specific needs of network users (speed, fair allocation of resources, and so on). 7. What types of transmission media are used in client/server networks? In addition to wireless media, three main cable types are used: twisted pair cable, coaxial cable, and fiber-optic cable. Twisted pair cable consists of four pairs of wires twisted around each other to reduce interference. Coaxial cable is the same type of cable used by your cable TV company to run a sig
