Two computers are connected together through their serial ports and Hyper-terminal communication software system. The data communication settings between the two computers are as follows: data transmission speed (bps) = 9600 data bits = 8 Parity bit = even stop bit = 2 start bit = 1 How much is the overall overhead in bits (extra bits transmitted with the file). The answer will be an integer number. Please do not put any comma in your answer.

Solution

Frame size for this serial communication is =

startbit+data bits+paritybit+stopbit= 1 + 8 + 1 + 2 = 12 bits

The frame size is of 12 bits.

The extra bits are start bit, stop bit and parity bit = 1 + 2 +1=4 bits

These 4 bits are the overhead bits in the transmission for a single byte of transfer.

Let\'s assume file size is of 100 bytes. Then the overall overhead bits transferred is 4*100*8=3200 bits
