Discuss About The Basic Components Of A Communication System?

Answer. There are three components on which a communication system can be based.
1. Transmitter
2. Channel
3. Receiver

Transmitter:
Transmitter is responsible for transmitting or sending the data. This data may be in the form of analog data stream or digital data stream.
1. The Transmitter is responsible for multiplexing data.
2. The Transmitter is responsible for modulating data.
3. The Transmitter is responsible for Encryption of data.
4. Transmitter is also responsible for Encoding of data as well as compression of data.

Channel:
Data transmitted by transmitter travel through the specified channel. There are different types of channels through which we can transmit the data. Data travels through these channels to reach there destination receiver.
List of these channels is given as below.
1. Copper cable.
2. Unshielded twisted pair / Shielded twisted pair(UTP/STP)
3. Air.
4. Fiber Optics.

Channels have a vital role in proper transmission of data but unfortunately every channel has impurities i.e. Attenuation, Delay Distortion and Noise which will cause a substantial decrease in the speed of data traveling.

Receiver:
Finally, the receiver receives the transmitted data from the specified channel. This data may be in the form of analog data stream or digital data stream.
1. The Transmitter is responsible for multiplexing data.
2. The Transmitter is responsible for demodulating data.
3. The Transmitter is responsible for decryption of data.
4. Transmitter is also responsible for decoding of data as well as decompression of data.
