Compare three types network topology

Answer 1

There are really three basic types of Network topologies. They are Star, Bus, and Ring. Let me explain them to you.

Star - All 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 transmits the data to the intended recipient rather than to all hosts on a network.

Bus - All computers and devices are connected in series to a single linear cable called a trunk or sometimes called a backbone. Both ends of the trunk must be terminated to stop the signal from bouncing back up the cable. Because the bus topology does not have a central point it is difficult to troubleshoot problems. Also, a break at any point along the bus can cause the entire network to go down.

Ring - In this topology, all computers and devices are connected to cable that forms a closed loop. Each 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. Similar to the Bus topology, if one computer fails, the entire network goes down.
