A factory immediately stops production when an environmental impact is discovered. An executive eliminates all professional development opportunities for em-ployees.: An executive eliminates all professional development opportunities for employees.

  1. What occurs in single contiguous memory management? A process is loaded into one designated memory block that follows the operating system. All processes are stored in memory blocks that come before the operating system. A single process is stored in separate, nonconsecutive blocks of main mem-ory. Multiple distinct sources of main memory are used to manage processes.: A process is loaded into one designated memory block that follows the operating system.
  2. What is a benefit to using paged memory management? It does not require a translation between logical and physical addresses. It allows multiple processes in memory without splitting them into pieces. It is the simplest of all techniques to implement and manage. A process no longer needs to be stored in a single memory block.: A process no longer needs to be stored in a single memory block.
  3. What is one characteristic of the dynamic-partition technique for creating partitions in partition memory management? The operating system's table of partition addresses will change as programs load and finish their execution. Memory is divided into fixed-size frames to minimize fragmentation. The operating system's table of partition addresses does not change once it is set. Address binding only needs to consider the location of the operating system.-
