1.Explain the advantages of viewing a process in terms of both a logical address space and a physical address space.

2. How does the logical vs. physical address space affect compilation, linking, and loading?

3. Explain the general approach taken to map from logical addresses to physical addresses (with protection) in computer hardware.

4. Consider a system in which a program can be separated into two segments: code and data. The CPU knows whether it wants an instruction (instruction fetch) or data (data fetch/store). This means that two base-limit register pairs can be used: one for instructions and one for data. Discuss the advantages and disadvantages of this scheme. (Hint: the instruction base-limit register pair can be read-only, so programs can be shared among different users.)
