How many characters per sec (7 bits + 1 parity) can be transmitted over a 2400 bps line if the transfer is synchronous ( 1 start and 1 stop bit)?
Ans A) 300
Total number of bits per character while transmitting is (7+1)=8 bits
No of character transmitted 2400/8=300 bps
Awesome tricky question!
For synchronous transfer, we don't need start and stop bits.
For asynchronous transfer, we need start and stop bits in order to synchronise!
