The function(s) of the Storage Assignment is (are)

• all of the choices

• to assign storage to literals, and to ensure that the storage is allocate and appropriate locations are initialized.

• to assign storage to all temporary locations that are necessary for intermediate results.

• to assign storage to all variables referenced in the source program.

The disadvantages of "Compile and Go" loading scheme is (are):

• a portion of memory is wasted because the core occupied by the assembler is unavailable to the object program.

• all of the choices

• it is necessary to retranslate the user's program deck every time it is run.

• it is very difficult to handle multiple segments, especially if the source programs are in different languages, and to produce orderly modular programs.

The strategy of making processes that are logically runnable to be temporarily suspended is called :

• First come First served

• Shortest job first

• Non preemptive scheduling

• Preemptive scheduling

Memory management is :

• replaced with virtual memory on current systems

• not used on multiprogramming systems

• critical for even the simplest operating systems

• not used in modern operating system

Swapping

• works best with many small partitions

• does not work with overlaying

• allows many programs to use memory simultaneously

• allows each program in turn to use the memory
