Advantages of data communication

1.Circutary becomes simpler than AC.

2.Highly resistive to noise as we are dealing with binary digits.

3.Highly secure.

4.Can travel long distances and can store data for long time.

5.AS we have regenerative repeaters & reconstruction filters in the receiver section we can extract original signal transmitted

6. Error correcting and detecting is easy.

7. A comman format is used for different kind of message signal such as speech signal and video signal.

8. Flexibility in configuring digital communication. digital hardware implimentation is flexible and permit the use of LSI. microprocessors anmd digital switches.
