Answer:
Computer Network Topology – Mesh, Star, Bus, Ring and Hybrid
Geometric representation of how the computers are connected to each other is known as topology. There are five types of topology – Mesh, Star, Bus, Ring and Hybrid.
Types of Topology
There are five types of topology in computer networks:
Types of Topology
1. Mesh Topology
2. Star Topology
3. Bus Topology
4. Ring Topology
5. Hybrid Topology
Mesh Topology
Mesh Topology
In mesh topology each device is connected to every other device on the network through a dedicated point-to-point link. When we say dedicated it means that the link only carries data for the two connected devices only. Lets say we have n devices in the network then each device must be connected with (n-1) devices of the network. Number of links in a mesh topology of n devices would be n(n-1)/2.
Star topology
❥ A star topology is a topology for a Local Area Network in which all nodes are individually connected to a central connection point , like a hub or a switch
- A star takes more cable than e.g. a bus , but the benefit is that if a cable fails only one node will be brought down .
Ring topology
❥ A ring topology is a network configuration where device connections create a circular data path .
- Each networked device is connected to two others , like points on a circle .
- They allow packets to travel only in one direction called a unidirectional ring network .
