Data Communicaton

Question 1

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

If one computer transfers a file size of 38400 bytes to other computer, how many frames of data will be formed for this data transfer. (The answer is an integer number)

Question 1A

In problem 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.

Question 1B

In problem 1. what is he efficiency of transmission in percent? The answer must be in percent with 2 decimal places; for example, 85.25% or 90.00%.

Question 1C

In Problem 1, what is the data transmission time in seconds. (the time that takes to complete the transmission of 38400 bytes and the extra bits). The number needs to be expressed in 2 decimal places; for example, 25.00 or 40.15. Please do not write anything else after the number.
