Definition of the Point-to-Point connection
Point-to-point is a type of line configuration that describes the method for connecting two communication devices in a link. The point-to-point connection is a unicast connection. There is a dedicated link between a single sender and receiver pair. The entire channel capacity reserved only for the transmission of the packet between the sender and the recipient.
Definition of multipoint connection
The multipoint connection is a connection established between more than two devices. The multipoint connection also called multidrop line configuration. In the multipoint connection, a single link shared by multiple devices. So, we can say that the channel capacity is shared temporarily by each device that connects to the link. If the devices use the connection shift after shift, it is said to be the configuration of the shared line over time.
Key differences between point-to-point and multipoint connection
- When there is only one dedicated link between two devices, a point-to-point connection while, if a single link shared by more than two devices, it is said to be a multipoint connection.
- In multipoint connection, the channel capacity is temporarily shared by the connected devices. On the other hand, in a point-to-point connection, the entire channel capacity reserved only for the two devices in the connection.
- In the point-to-point connection, there can be only one transmitter and a single receiver. On the other hand, in the multipoint connection, there is a single transmitter and there may be multiple receivers.
Both point-to-point and multipoint are the types of line configuration, which refers to the technique for connecting two or more communication devices.
If you want to send data to multiple recipients, using the point-to-point connection will create more overload, while the multipoint connection will be more useful.
