2. Suppose a file of 35,000 characters is to be sent over a line at 55,000bps.
1. Calculate the overhead in bits and time using asynchronous transmission. Assume 1 start bit and 1 stop bit and 8 bits to send the character itself for each character.
2. Calculate the overhead in bits and time using synchronous communication. Assume the data is sent in frames. Each frame consists of 1000 bytes and overhead of 48 bits per frame for control, error detection etc.
