Calculate message latency for a 25 Kbit message with a bitrate of 100 Kbits/second and a propagation delay of .25 seconds.  Show your calculations and remember to indicate the unit of measurement for all quantities.

Suppose parity(bitstring) is equal to 1 if there are an odd number of ones, otherwise it is 0.  If a host receives the bitstring 101011011, what does it mean, and should happen next?

Suppose you wanted to use public-key cryptography to submit a final paper via email so that only your instructor could read it. Which key would your instructor use to decrypt your submission?

How would recording (i) with a sampling rate of 20kHz recorded and using 8 bits/sample differ from recording (ii) with a sampling rate of 20kHz and using 16 bits/sample?

[Optional] You may add notes about the prior question here.

Suppose you took a digital picture of a poster that used only sixteen distinct colors, and you want to compress it.  If your digital camera stores pictures using a color depth of 64 thousand colors (that is, 16 bits per pixel) you could save a lot of file space by reducing the number of bits used for each pixel. What would be the optimal number of bits to use?  Show your calculations.

What type(s) of modulation are illustrated in the figure to the below?
