ICT 3rd Quarter reviewer quiz - Topology & Operating Systems

It is a telecommunications network which allows computers to exchange data. In computer networks, networked computing devices exchange data with each other using a data link. The connections between nodes are established using either cable media or wireless media.

(a)  

All of them are disadvantages of Mesh, EXCEPT

• Cost is very high compare to other topologies

• Failure link will cannot stop data transmission from sender to receiver

• Most of bandwidth wasted

• Building and maintaining mesh is to difficult and time consuming

All of them are advantages of Star, EXCEPT

• If the hub fails then the whole network is stopped because all the nodes depend on the hub.

• Fast performance with few nodes and low network traffic.

• Easy to troubleshoot.

• Only that node is affected which has failed, rest of the nodes can work smoothly.

All of them are advantages of Star, EXCEPT

• Hub can be upgraded easily.

• Performance is based on the hub that is it depends on its capacity.

• Easy to setup and modify.

• Fast performance with few nodes and low network traffic.

All of them are the disadvantages of Ring, EXCEPT

• Failure of one computer disturbs the whole network.

• Adding or deleting the computers disturbs the network activity.

• Transmitting network is not affected by high traffic or by adding more nodes, as only the nodes

• Troubleshooting is difficult in ring topology.

All of them are disadvantages of Ring, EXCEPT

• Failure of one computer disturbs the whole network.

• Cheap to install and expand

• Adding or deleting the computers disturbs the network activity.

• Troubleshooting is difficult in ring topology.

All of them are advantages of Bus, EXCEPT

• It is cost effective.

• It is easy to understand.

• It is slower than the ring topology.

• Easy to expand joining two cables together

Allows different parts of a single program to run concurrently.

• Multitasking

• Multithreading

• Multi-user

• Real time

Allows more than one program to run concurrently.

• Multithreading

• Multithreading

• Multi-user

• Multitasking

All of them are the advantages of Bus, EXCEPT. (2)

• Cable required is least compared to other network topology.

• Easy to expand joining two cables together

• It is easy to understand.

• If network traffic is heavy, the performance of the network decreases.
