Question

advantages of ring topology

Answer 1

Explanation:

thanks dear friend

I hope you help

Answer 2

Answer:

Advantages:-

• Very orderly network where every device has access to the token and the opportunity to transmit.

• Performs better than a star topology under heavy network load.

• Can create much larger network using Token Ring.

• Does not require network server to manage the connectivity between the computers.

• Data is quickly transferred without a "bottle neck". (very fast, all data traffic is in the same direction).

• The transmission of data is relatively simple as packets travel in one direction only.

• It prevents network collisions because of the media access method or architecture required.

• Adding additional nodes has very little impact on bandwidth.

Disadvantages:-

• One malfunctioning workstation or bad port in the MAU can create problems for the entire network.

• Data packets must pass through every computer between the sender and recipient therefore this makes it slower.

• Moves, adds and changes of devices can affect the network.

• Network adapter cards and MAU's are much more expensive than Ethernet cards and hubs.

• Much slower than an Ethernet network under normal load.

• A physical ring topology uses a single length of cable interconnecting all computers and forming a loop. If there is a break in the cable, all systems on the network will be unable to access the network. Total dependence upon the one cable.

• All Network Interface Cards (NICs) on the ring network must operate at the same speed.

• The MSAU on a logical ring topology represents a single point of failure. If all devices are unable to access the network and there is no cable break, it might be that the MSAU is faulty.

• Because all stations are wired together, to add a station you must shut down the network temporarily.

• Difficult to troubleshoot a ring network.

• In order for all computers to communicate with each other, all computers must be turned on.
