A Point to point provides a dedicated link between two devices.
A network is two or more devices connected through a link. A link is a communication pathway that transfer data from one device to another. Devices can be a computer, printer or any other device that is capable to send and receive data. For visualization purpose, imagine any link as a line drawn between two points.
The main difference between point-to-point and multipoint connection is that in a point-to-point connection the link is only between two devices i.e. a sender and a receiver. On the other hand, in a multipoint connection ,the link is between a sender and multiple receivers.
Difference between the communication and transmission.Transmission is a physical movement of information and concern issues like bit polarity, synchronisation, clock etc.Communication means the meaning full exchange of information between two communication media.
