Draw how a series of four separate messages would be successfully sent from one computer to
another if the first message were transferred without error, the second were initially transmitted with
an error, the third were initially lost, and the ACK for the fourth were initially lost.
. How efficient would a 6-bit code be in asynchronous transmission if it had 1 parity bit, 1 start bit, and
2 stop bits? (Some old equipment uses 2 stop bits.)
