Problem $1.$ Communicating with I$/$O devices is achieved using combinations of polling, interrupt handling, memory mapping, and special I$/$O commands. Answer the question about communicating with I$/$O subsystems for the following applications using combinations of these techniques.

$1)$ Auto Pilot

$2)$ Automated Thermostat

Describe device polling and interrupt driven communication. Would each application be appropriate for communication using polling techniques? Explain. For each application, if polling is inappropriate, explain how interrupt driven techniques could be used.
