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. 

The intensity at pixels ‘a’, ‘b’, and ‘c’ in a given image are 50, 60, and 100. Find out which of the pixels do not belong to same camera system if identical image sources are located at 10mt, 8mt, and 7.1mt respectively. Assume Gamma γ to be 1 for the given imaging systems.
