What is Network Topology?
A network is physically organized in accordance with different approaches to cabling system and the way devices communicate with each other. The physical order of computers within a network is defined as “network topology”. The main topological types are bus (linear placement), ring (ring placement), and star topologies.
In a bus topology, workstations are located on a linear line (e.g. ethernet local area network). There are terminators on both ends of the linear line. Servers are connected to the network via a network interface card.
Servers and devices in a ring topology are set up to form a circle and are called “token ring” networks. In ring topology network, “token”, i.e. data frame, organizes communications with the custom control code that is constantly rotating within the network. This method prevents the cable from being used at the same time.
In this layout, workstations are distributed in the form of stars. In the centre of the star, a hub or switch connects all the points connected to them. One end of the cable is connected to the network adapter card while the other is connected to the hub or switch. The network is controlled from a single point, and each workstation is individually routed.
