1. Suppose you sent 46K bytes across a short RS-232 connection that operated at 19,200 bits/sec. How long would the transmission take? (hint: dont forget overhead bits.)

2. Consider a transmission system that provides 4000 Hz of bandwidth and uses 16 different values to encode the information. For an ideal system with no noise, what is the maximum data rate possible? If the system has 28 dB signal to noise ratio, what is the maximum data rate possible?

3. Imagine you are going to install several robotic arc welders that are bolted to a machine shop floor. These robots are to be networked to a central controller. What networking media would be appropriate to use? (note: arc welders can generate a lot of electrical noise.)
