Answer / saikiran

Both the interfaces have it own importance,
in serial the data is transmitted in sequence i.e is 1 bit
at a time for one clock cycle so to transfer 8 bits of info
you need 8 clock cycles in short it takes more time
comparatively.
where as in parallel 8 bits of transmission is transmitted
is in 1 clock cycle.
parallel transmissions normally used for tarnsmited data
from computer to printer(through LPT port)
parallel transmission is faster than serial transmission.

Answer / daya

Parallel interface works efficiently for short transmittance
distance, for longer ranges the link cribs because of EMI
and other interferences.
Serial on the other hand supports longer ranges as it is a
sole carrier of bits

so long range and slow transmission :serial
short range and faster transmission : parallel

Answer / anil

Parallel communications is faster upto some clock frequency,
after some threshold it deteriorates due to cross talk.
Hardware need to be designed complex to overcome this issue,
instead serial communication offers better speed at higher
frequencies due to less hardware complexities.
