उत्तर
In point to point mode of communication, information is sent from a sender to specific receiver, i.e., from one point to another point and in broadcast mode, the information is broadcasted to all receivers simultaneously.
An example of point to point communication is a telephone where one telephone is connected to just one other at a time. A radio or television can be an example of broadcast mode where there are many receivers available at one time.
