A logistics company is designing a simulation to optimize a fleet of 1,000 autonomous delivery drones. Each drone is programmed with its own set of rules to decide its route based on local weather, battery status, and the proximity of other drones. The goal is to observe how these individual behaviors lead to an efficient delivery network without a central controller.

Which computational model is most appropriate for this simulation, and why?

A temperature control system in a greenhouse reads data from a thermistor, compares the value against a target temperature, and then activates a ventilation fan if the greenhouse is too hot. In the Input-Process-Output (IPO) model, which action constitutes the 'Process' phase?

A high-speed automated toll booth system captures photos of passing cars, uses software to extract the license plate text, and then sends a bill to the registered owner.

a) Within the Input-Process-Output (IPO) model, identify one specific Input and one specific Output for this system.
b) The system is updated to use a parallel computational model instead of a sequential one. Explain the fundamental difference in how instructions are handled in a parallel model compared to a sequential model.
