A metropolitan area network (MAN) connects individual computer resources in an area of up to cem kilometers. Smaller than a wide area network, it’s an efficient option for secure and stable data transfer within areas that are too large for a local area network. We’ll explain what…

Bus Topology: In bus topology all devices are connected to a single central cable called a bus. Data is sent along this cable and all devices share the same connection. Simple and cheap to set up but if the main cable fails the whole network goes down.

For example, the application layer is used to define where, when and how much data should be sent at a specific rate.
