Question

A point-to-point communication mode is seen in
A) Satellite cable communication
B) Television transmission
C) FM radio transmission
D) AM radio transmission
E) Fax transmission

Answer 1

Hint:We can understand the meanings and references of the types of mode of communication as point-to-point communication falls under that category and then evaluate the options to get the correct one.

Complete step by step answer:
Communication means the transfer of some information from one end to another.The sender of this information is called transmitter (source), the receiver is called receiver only and through which it is transmitted is called channel or medium.
Now, there are two modes of communication:
1. Point to point: When there is only one receiver of any information from a source, it is called point to point transmission. The signal is transmitted through a common link between the transmitter and the receiver. E.g. Telephones.
2. Broadcasting: When there are more receivers (multiple in number) to receive the information from a source, it is called broadcasting. E.g. Television broadcasting
Checking out the options:
-FM Radio transmission and Television transmission is to reach out the maximum people, these are the most common ways of communication through broadcasting.
-Satellite cable communications are generally used for television transmissions or other transmissions to reach a large number of people at once.
-AM radio is nothing different than FM radio, it was used in earlier times for broadcasting the information by modulating the amplitude (AM). In fax transmission, the information is sent from a source to one receiver through a particular link.
Therefore, it can be concluded that a point-to-point communication mode is seen in fax transmission and the correct option is E).

Note: These information are generally transmitted in the form of signals (mostly electrical) through a long process in a very short period of time.In modern systems for communication, the information is sorted, processed and sometimes stored before transmission.
