modes of operation

1. Some early computers protected the operating system by placing it in a memory partition that could not be modified by either the user job or the operating system itself. Describe two difficulties that you think could arise with such a scheme.

2. Some CPUs provide for more than two modes of operation. What are two possible uses of these multiple modes?

3. Timers could be used to compute the current time. Provide a short description of how this could be accomplished.

4. Give two reasons why caches are useful. What problems do they solve? What problems do they cause? If a cache can be made as large as the device for which it is caching (for instance, a cache as large as a disk), why not make it that large and eliminate the device?

5. Distinguish between the client–server and peer-to-peer models of distributed systems
