Multiple choice

How many characters per sec (7 bit + 1 parity) can be transmitted over a 2,400 bps, if the transfer is asynchronous (1 start and 1 stop bit)?

  1. 300

  2. 240

  3. 250

  4. 275

B Correct answer
Explanation

Each character requires 7 data bits + 1 parity + 1 start + 1 stop = 10 bits total. At 2400 bps: 2400 / 10 = 240 characters per second. The overhead bits reduce effective throughput.
