Question 1. Most modern processors provide two modes of operation: user mode and kernel mode. Please answer the following questions concisely in a bullet point format. (a) What are the main differences between these two modes? (b) From the viewpoint of operating systems, why are they needed? (c) What are the main differences between mode switch and context switch? (d) What are the pros and cons of micro-kernel structures in operating systems?
