Peer-to-peer networks are often used for file sharing and communication between computers. The main advantage of using a P2P network is its ability to provide high availability and fault tolerance. If one computer in the network goes down, others can continue working as if nothing happened.

They are more common in homes, while client/server networks are more likely to be used by small to medium size businesses.

A ring topology is like a bus topology because it uses a single cable with the end nodes connected to each other so the signal can circle through the network to find its recipient. The signal will try several times to find its destination even when the network node is not working properly.

A collapsed ring topology has a central node, which is a hub, router, or switch. These devices have an internal ring topology and places for cables to plug in. Every computer in the network has its own cable to plug into the device. In an office, this probably means having a cabling closet, where all computers are connected to the closet and switch.
