Topology
Bus Topolpgy
| Advantages |
Disadvantages |
| Simple and very reliable |
A large amount of traffic slows the network down |
| Cabling, relatively inexpensive, easy to install, and network easily
expanded. |
A cable break or lack of termination brings the entire network down |
| Cabeling is cheap because all the computers are arranged in a row. |
Network problems may be difficult to troubleshoot. |
Ring Topology
| Advantages |
Disadvantages |
| All computers have equal access to the network with a token ring. |
A single computer failure can affect the whole network. |
| Network performance is even no matter how many users are working. |
May be difficult to troubleshoot the problems. |
| � |
Network disruptions occur when computers are added or removed. |
Star Topology
| Advantages |
Disadvantages |
| Easy to add computers or modify the network. |
The entire network fails if the central hub fails to operate. |
| Centralization of network allows for easy management and monitoring. |
The complex network structure requires more cableing. |
| If a single computer fails, the entire network is still functional. |
