Question

Which of the following is not a component of a communication system?

• A. Transmitter
• B. Transmission channel
• C. Noise
• D. Receiver

Answer 1

The correct option is C

Noise

Explanation for the correct answer:

In case of option C.

1. Noise in a communication system is basically undesirable or unwanted signals that get randomly added to the actual information-carrying signal.
2. Noise refers to anything that interferes with the communication process between a speaker and an audience. It's also called interference.
3. Thus, it is not a component of a communication system.
4. Hence option C is the correct option.

Explanation for the incorrect answers:

In case of option A.

1. A transmitter is an electronic device used in telecommunications to produce radio waves in order to transmit or send data with the aid of an antenna.
2. The transmitter is able to generate a radio frequency alternating current that is then applied to the antenna, which, in turn, radiates this as radio waves.
3. Thus, it is an important part of the communication system.
4. Hence, option A is an incorrect option.

In case of option B.

1. Communication channels are mediums through which you can send a message to its intended audience.
2. For example, phone calls, text messages, emails, video, radio, and social media are all types of communication channels.
3. Thus, it is an important part of the communication system.
4. Hence, option B is an incorrect option.

In case of option D.

1. A receiver is a person or a device who gets the message and tries to understand what the sender actually wants to convey and then responds accordingly.
2. This is also called decoding.
3. Thus, it is an important part of the communication system.
4. Hence, option D is an incorrect option.

Hence option C is the correct option.
