Operating Systems: Memory Management Techniques

Memory Management Techniques

APA Format 500+ words and Citation/Reference requirements: include at least two high quality references and show citations per APA standard.

Discuss the strengths and weaknesses of the following memory management techniques:

• Fixed      Partitioning: Main memory is divided into a number of static      partitions at system generation time. A process may be loaded into a      partition of equal or greater size.
• Dynamic      Partitioning: Partitions are created dynamically, so that each      process is loaded into a partition of exactly the same size as that process.
• Simple      Paging: Main memory is divided into a number of equal-size      frames. Each process is divided into a number of equal-size pages of the      same length as frames. A process is loaded by loading all of its pages      into available, not necessarily contiguous, frames.
• Simple      Segmentation: Each process is divided into a number of segments.      A process is loaded by loading all of its segments into dynamic partitions      that need not be contiguous.
• Virtual-Memory      Paging: As with simple paging, except that it is not necessary to      load all of the pages of a process. Nonresident pages that are needed are      brought in later automatically.
• Virtual-Memory      Segmentation: As with simple segmentation, except that it is not      necessary to load all of the segments of a process. Nonresident segments      that are needed are brought in later automatically.
