Microsoft Certified Systems Engineer (MCSE) Question:
What are network topologies? Explain Ring, Bus and Star topology.
Answer:
A network topology describes the layout of a network. It describes how different nodes and elements are connected to each other. Different types of topology:
a. Ring:-
* All nodes connected with another in a loop.
* Each device is connected to one or more another device on either side.
b. Bus
* All nodes connected to a central and a common cable called as a back bone.
* In bus topology, the server is at one end and the clients are connected at different positions across the network.
* Easy to manage and install.
* If the backbone fails, the entire communication fails.
c. Star
* All nodes connected to a central hub.
* The communication between the nodes is through the hub.
* Relative requires more cables as compared to BUS. However if any node fails, it wont affect the entire LAN.
