- 1What is a Network Topology ?A way of connecting two or more systems into one network, for example; Bus, Star, Ring, Tree, Mesh.
- 2What is a bus topology ?An arrangement of computers in a local- area network to a central cable where the data is channelled.
- 3What are the advantages of bus topology?Easy to install.
Affordable to install as don't require much cable. - 4What are the disadvantages of bus topology ?If the main cable is damaged then the network would fail.
As workstation increase the slower the network due to data collision. - 5What is Ring Topology ?This is when each device (workstation, server, printer) is connected to two other devices, this forms a ring for the signals to travel around.
- 6What is the advantages of ring topology ?This type of network can transfer data quickly, even if there are a large number of devices connected because the data only flows in one direction, so there won’t be any data collisions.
- 7What is the disadvantage of ring topology ?If the main cable fails or any device is faulty then the whole network will fail.
- 8What is Star topology ?This is when each device on the network has its own cable that connects to a switch or hub. A hub sends every packet of data to every device, whereas a switch only sends a packet of data to the destination device.
- 9What are the advantage of star topology ?Very reliable – if one cable or device fails then all the others will continue to work.
High performing as no data collisions can occur. - 10What are the disadvantages of star topology ?Expensive to install as this type of network uses the most cable (network cable is expensive).
If a hub or switch fails all the devices connected to it will have no network connection.
Extra hardware required (hubs or switches) which adds to cost. - 11What is a tree topology ?This is used to connect a node to another, and it is valued for its access to troubleshoot.
- 12What are the advantages of a tree topology ?Error detection and correction is easy.
Expansion of the network is possible and easier.
If one segment is damaged , other segments are not affected. - 13What are the disadvantages of tree topology ?As more and more nodes and segments are added, the maintenance becomes difficult.
Scalability of the network depends on the type of cable used. - 14What is Mesh topology ?This is a network in which each node relays data for the network.The nodes work together to share the data in the network.
