Star Topology
In a Star Topology, all the nodes (PCs, printers and peripherals) are connected to the central server. It has a central connection point, like a hub or switch. In star topology .each device is connected with central hub.
Advantages of Star Topology
- If N devices are connected to each other in a star topology, then the number of cables required to connect them is N. So, it is easy to set up.
- Each device requires only 1 port i.e. to connect to the hub, therefore the total number of ports required is N.
- It is Robust. If one link fails only that link will affect and not other than that.
- Easy to fault identification and fault isolation.
- Star topology is cost-effective as it uses inexpensive coaxial cable.
Disadvantages of Star Topology
- Star networks can require more cable length than a linear topology.
- More expensive cabling.
- Performance is based on the single concentrator i.e. hub.
Network Topology
In Computer Networks, Network Topology is the arrangement of the various elements of a communication network. Network Topology is a topological structure of a network and may be depicted physically or logically. In this article, we are going to discuss network topology and its various types.
