UGC-NET | UGC NET CS 2014 Dec – III | Question 26

  • Last Updated : 01 Apr, 2021

How many characters per second (7 bits + 1 parity) can be transmitted over a 3200 bps line if the transfer is asynchronous ? (Assuming 1 start bit and 1 stop bit)
(A) 300
(B) 320
(C) 360
(D) 400


Answer: (D)

Explanation: In Asynchronous:
7+1+1+1=10

Through channel : 3200 bit in 1 sec
Then through channel character per second is : 3200/10 = 320

In case of synchronous data :
we transfer only data & parity bits = 7+1 = 8

Through channel: 3200 bit in 1 sec
Then through channel character per second is : 3200/8 = 400
