The physical topology of a network refers to the configuration of cables, computers, and other peripherals. Physical topology should not be confused with logical topology which is the method used to pass information between workstations. 

           Main Types of  Topologies:─

The following sections discuss the topologies used in networks . 
  • Linear Bus 
  • Star 
  • Star-Wired Ring 
  • Tree 

             Linear Bus

A linear bus topology consists of a main run of cable with a terminator at each end. All nodes (file server, workstations, and peripherals) are connected to the linear cable. Ethernet and Local Talk networks use a linear bus topology


A star topology is designed with each node (file server, workstations, and peripherals) connected directly to a central network hub  on a star network passes through the hub before continuing to its destination. The hub manages and controls all functions of the network. It also acts as a repeater for the data flow. This configuration is common with twisted pair cable & also used with coaxial cable or fiber optic cable.


             A tree topology combines characteristics of linear bus and star topologies. It consists of groups of star-configured workstations connected to a linear bus backbone cable.
