For what purpose is a PNP junction transistor is used? Explain in detail how it is used. 
b) If you have pure Si, P, Ge, As, Ga, and Al materials which ones would you choose to create a PNP junction transistor and why?

In this stage, you will review the physical connections and operation of RS-232.
1. List the name of each signal/pin of a 9-pin RS-232 connector.
2. List the purpose of each signal/pin you listed in (1).
3. Identify the voltages that represent each logic level for all the signals you listed in (1).
4. Describe the sequence of signals asserted when a Data Terminal Equipment (DTE)
wants to send data to a Data Communication Equipment (DCE). Clearly indicate the
direction of each signal.
