Ringtopology: In this topology, all computers and devices are linked or connected to the cable that forms a closed loop. Every single computer on this type of topology acts like a repeater and boosts the signal before sending it to the next computer. It transmits data by passing a “token” around the network. Hence this type of network is commonly called a token ring network. Alike to the Bus topology, if one computer fails, the whole network goes down. Bus topology: Entirely computers and devices are connected in series to a single linear cable called a trunk or sometimes can called a backbone. Both ends of the trunk must be terminated to stop the signal from bouncing back up the cable. For the reason that the bus topology does not have a central point it is difficult to troubleshoot problems. Besides, a break at any point along the bus can cause the entire network to go down. Star topology: Every computers and devices are connected to a centrally located hub or switch. The hub or switch collects and distributes the flow of data within the network. It’s better to use a switch than a hub because a switch transfers the data to the intended recipient rather than to all hosts on a network. 8.
