Describe one common process scheduling algorithm and its advantages.
First-Come, First-Served scheduling algorithm is efficient for all process types.
Round Robin scheduling algorithm is advantageous because it ensures fair allocation of CPU time among processes, reduces waiting time for shorter processes, and is simple to implement.
Shortest Job Next scheduling algorithm prioritizes longer processes.
Priority scheduling algorithm can lead to starvation of shorter processes.

What is an interrupt and how does it affect process scheduling?
An interrupt is a signal that only affects hardware components, not process scheduling.
An interrupt is a method to increase the CPU's processing speed by ignoring lower-priority tasks.
An interrupt is a signal that temporarily halts a process to allow the CPU to address a higher-priority task, affecting process scheduling by enabling immediate response to urgent events.
An interrupt is a permanent stop of a process that cannot be resumed.
