On a serial data link characters are transmitted data rate of 9600 baud. if characters are 8 bits and there is one start bit and one stop bit per character, then what is the number of characters transmitted per second.

Can someone explain to me how to get the answer.The given question is a multiple choice question (MCQ), so a short answer would work.Thanks in advance

You will have 8 + 1 + 1 = 10 bits per character. With 9600 baud, meaning bits/s, this means you can send 9600 bits/s / 10 bits/character = 960 characters/s.

Note, if a parity bit is used, 11 bits per character should be used for the calculation above.

    \$\begingroup\$ For future reference: Here on EE.SE, we don't provide direct answers to homework/exam questions, we only provide hints or Socratic questions, and only when the OP has demonstrated sufficient effort on their own. Otherwise, we would be doing them a disservice, and getting swamped by homework questions at the same time. See also here. \$\endgroup\$
