Q-suppose a system uses priority scheduling (where a small integer number means a high priority)

Processes in system
processes	Required processing time	priority
0	60	3
1	10	4
2	40	1
3	80	2

i- with time quantum 50 ms, if a single context switching process requires 1ms, calculate the CPU utilization of the system, and what are the effects of increasing and decreasing of time quantum for the round-robin scheduler?

ii- Discuss the relationship between the context switching and the CPU utilization in the embedded system. Justify how this relationship affects the characteristic of batch system and interactive system?
