What does sharing accomplish in memory management? Removes modules from physical page frames temporarily Allows multiple processes to use the same common data Consolidates multiple unused areas into one area Resolves external references among object modules What does the memory allocator do that results in external memory fragmentation? Leaves sections of unused memory blocks between portions of allocated memory Leaves extra space empty in a block of memory that has been allocated for a progra Allocates contiguous system memory pages Allocates more memory than an individual page can hold Which memory management search strategy looks for the largest available hole for any memory request? Next-fit Best-fit First-fit Worst-fit What is a characteristic of a real-time process? Presence of continual input requiring nearly instantaneous output Performance of multiple computations to be executed as a batch Presence of communication with the user in the form of a dialog Performance of a long-running task without user intervention
