What is an advantage of a large scheduling quantum and What is a disadvantage?

An advantage of a large scheduling quantum is that it can reduce the overhead associated with context switching, as processes are allowed to run for longer periods before being interrupted, leading to better CPU utilization. However, a disadvantage is that it can lead to poor responsiveness for interactive applications, as longer quantum times may cause delays in the execution of high-priority or time-sensitive tasks, potentially resulting in a sluggish user experience.
