What is LAN? Explain with the help of diagram, any two LAN topologies.. Also mention their advantages and disadvantages
Answers
It is a connected set of computers and other devices. Each device is called node (example : computer, printer, etc.).
LAN topologies are Ring topology, Star topology and Bus topology.
Ring topology : connects all nodes in a closed loop on which messages travel in one direction.
Star topology : centers around one node to which all others are connected and through which all messages are sent.
Bus topology : nodes are connected to a single communication line that carries messages in both directions.
LAN advantages :
- improves productivity due to faster work.
- provides easy maintenance.
- new systems can be installed and configured easily.
disadvantage :
- limited number of systems can only be connected.
- cannot cover large area.
-network performance degrades as number of users exceeds.
