Question 1: CD-quality music requires sampling the sound signal 44,100 times per second. Suppose that a timer generates an interrupt at this rate and that each interrupt takes 1 microsec to handle on a 1-GHz CPU. What is the slowest clock rate that could be used and not lose any data? Assume that the number of instructions to be processed for an interrupt is constant, so halving the clock speed doubles the interrupt handling time.
Question 2: What is the difference between a physical address and a virtual address?
Question 3: Explain the difference between internal fragmentation and external fragmentation. Which one occurs in paging system? Which one occurs in system using pure segmentation?
