Answer:
C) Flight Simulation software offers pilots a more authentic training experience compared to actual flight sessions.
Explanation:
Flight simulation programs are utilized to instruct future pilots in aviation schools. They replicate the circumstances that pilots will likely encounter during real flights and how to manage them.
This software enables pilots to rehearse landings across various types of landscapes and weather conditions without geographical limitations.
Additionally, it is cost-effective by reducing expenses on fuel and maintenance related to actual training flights.
Nevertheless, it does not engage pilots in a more authentic experience than actual training flights.
Answer:
For I/O-bound applications, we require voluntary context switches.
For CPU-bound applications, non-voluntary context switches are necessary.
Explanation:
A voluntary context switch happens when a process relinquishes control of the CPU because it needs a resource that isn't currently available (like waiting for I/O). This occurs quite frequently during regular system operations, typically initiated by a call to the sleep() function.
A non-voluntary context switch occurs when the CPU is forcibly taken from a process, possibly due to the expiration of its time slice or preemption by a higher-priority task. This is enacted through direct calls to low-level context-switching functions like mi_switch() and setrunnable().
