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).
