CSIT 220: The Week beginning Sept. 6

• Reading: Chapters 5, 6 and 7 in Computer Networks and Internets (Comer)

• Homework:
  • Comer Question 5.3. Suppose one sent 10,000 7-bit characters across an RS-232 connection that operated at 9600 baud. How long would the transmission require? (Hint: remember to allow for a start bit and a stop bit on each character.) For simplicity, assume one bit per baud.
  • Give a name/description of the pins in a DB9 connector. (A possible source is http://computer.howstuffworks.com/serial-port.htm/printable)
  • What is "hand shaking"?
  • What is meant by category 5? Where/when would you use it? Why?
