Network Topologies

A network’s shape or geometrical arrangement of computers is known as Network Topology. It represents the physical arrangement of systems, communication devices and network cable. The most common topology or general configuration of networks include

  • Bus Topology
  • Star Topology
  • Ring Topology

Bus Topology: A bus topology uses a single transmission medium called a bus. A coaxial cable serves as the transmission medium. All computers will be connected directly to this bus. It requires special end connectors (terminators) to both ends of the bus. Data can flow in either direction of the bus.

Star Topology: In this topology, all computers or nodes are connected to a central computer. The central computer transmits data to all the connected nodes. Direct connections between computers do not exist in this star topology.

Ring Topology: In a ring topology, the network has no end connections. The network forms a continuous ring without any break in the path. Data flows in only one direction around the ring.
