Synchronous-and-asynchronous-Communication
Question 1 |
How many ASCII characters can be transmitted per second over a 2400bps line if the transfer is asynchronous with start and stop bits in addition to parity bit with each character?
300 | |
240 | |
340 | |
2400 | |
None of the Above |
Question 1 Explanation:
To transfer 1 character of 8 bit we need
8 bit + 1 start bit + 1 stop bit + 1 parity bit = 11 bit.
Hence no. of characters that can be transmitted per second is = 2400/11 = 218
8 bit + 1 start bit + 1 stop bit + 1 parity bit = 11 bit.
Hence no. of characters that can be transmitted per second is = 2400/11 = 218
Question 2 |
In asynchronous serial transfer of characters, which of the following ordered pair of bits represents the used as delimiters for every character.
0,1 > | |
(00,01>
