Give several reasons why it is useful to separate a process’s virtual memory space from its physical memory space.

What will be an ideal response?


For one thing, if the spaces were identical, there would be little point in having a virtual
memory space. The separation gives users the freedom to write programs much larger
than physical memory, frees them from worry about memory management such as overlays
and enables the interuser protection mechanisms which are such a nice feature of virtual
memory systems.

Repeat Exercise 12 in Chapter 7, but use an instance of ArrayList instead of an array. Make the following slight changes to the methods to reflect that an ArrayList object can grow in size:

• Change the constructor’s parameter from the maximum degree to the desired degree. • The method setConstant might need to add zero-valued coefficients before ai. For example, if a0 = 3, a1 = 5, a2 = 0, a3 = 2, a4 = 0, and a5 = 0, the polynomial would be of degree 3, since the last nonzero constant is a3. The invocation setConstant(8, 15) would need to set a6 and a7 to 0 and a8 to 15.
