Differentiate between the serial transmission and parallel transmission.

 

Ans. The difference between the serial transmission and parallel

transmission is given below –

 

S.No.    Parallel Transmission                  Serial Transmission

(i)          This type of transmission                In this transmission, all the bits

permits the transmission of a         are transmitted one after another.

x group of bits simultaneously.

(ii)        Separate lines are used for              Just one line is used for transmitting

each group.                                           mission.

(iii)       This transmission is suitable          This transmission is suitable

for short distance.                                for long distances.

(iv)         This transmission is expensive.        It is cheaper in comparison.

(v )         This transmission is not                     This transmission is more reliable.

(vi)        It takes less time in transmi-             It takes more time in transmission.

(vii)      Transmission circuitry is                    Transmission circuitry is complex

simple.                                                     due to sending and receiving

parallel transmission.
