Type of connection

A network consist of two or more devices connected through links.A link is a communication pathway that transfers data from one device to another. Fro visualizations purposes, it is simplest to imagine any link as a line drawn between to points.For communication to occur, two devices must be connected in some way to the same link at the time.There are two possible types of connections: point-to-point and multipoint.A point-to-point connection provides a dedicated link between two devices, and the entire capacity of the link is reserved for transmission between these two devices.A multipoint connection is one in which more than two specific devices share a single link. In a multipoint environment,the capacity of the channel is shared, either spatially or temporally.
