Difference between Point-to-point and Multipoint Connection



A network is two or more devices connected to each other though connecting links. Network structure can be identified as physical or logical. Physical topology specifies the placement of various network components while on the contrary logical topology specifies how the data is transmitted from one point to another point in the network. There are two possible ways to connect the devices.

1.    Point to point connection
2.    Multipoint connection


Point-to-point Connection:

A point to point connection is a simplest topology which provides a dedicated link between two devices. Entire capacity of the link is reserved for transmission between the two connected devices only. It is possible to connect the two devices by means of a pair of wires or using a microwave or satellite link. There is a single transmitter and a single receiver in point to point connection.

The point-to-point may be defined as a line configuration which connects two communication devices directly. The capacity of the entire channel is reserved only for the transmission of the packet between the sender and receiver.



Multipoint Connection:

In multipoint connection, more than two devices share a single link. A multipoint connection is also called a multidrop connection. In the multipoint connection, the channel capacity is shared. If many devices share the link simultaneously, it is called spatially shared connection. But, if users share it turn by turn then it is time sharing connection.
