Answer / rinkesh

in the digital communication only two types of voltage levels
are use for communicate the information.
that are high voltage level called bit-1 (5V TTL)
and low voltage level called bit-0 (0V TTL).
so the pattern use in digital communication is made of two
bits 0s and 1s only.

Answer / hems

Digital communication also called as data transmission in
which it converts analog signal(current, voltage or electric
charge) to digital form either it is 0 or it is 1... For
example e-mail in computer....digital communications is the
transfer of discrete messages... For long distance it needs
Modulation so we are used PCM(Pulse Code Modulation)...
