Differences between Point-to-Point and Multi-point Communication

In this section, we shall see the differences between Point-to-Point and Multi-point Communication. In point-to-point communication, there is a dedicated link between two nodes, and in multi-point communication, the link is provided at all times for sharing the connection among nodes. 

Now, the differences between these to communicate with the help of diagram are given below: 

S.NO	Point to point communication	Multipoint Communication
1.	Point to point communication means the channel is shared between two devices.	Multipoint Communication means the channel is shared among multiple devices or nodes.
2.	In this communication, There is dedicated link between two nodes.	In this communication, link is provided at all times for sharing the connection among nodes.
3.	In this communication, the entire capacity is reserved between these connected two devices with the possibility of waste of network bandwidth/ resources.	In this communication, the entire capacity isn’t reserved by any two nodes and the network bandwidth is maximum utilized.
4.	In this communication, there is one transmitter and one receiver.	In this communication, there is one transmitter and many receivers.
5.	In point-to-point connections, the smallest distance is most important to reach the receiver.	In Multi-point connections, the smallest distance is not important to reach the receiver.
6.	Point-to-point communication provides security and privacy because communication channel is not shared.	Multi-point communication does not provide security and privacy because communication channel is shared.
