Goal of Memory Management. Memory management is part of an operating system which allocates memory among competing processes, maximizing memory utilization and system throughput. Master the concepts of hierarchical memory organization.. Understand how each level of memory contributes to system performance, and how the performance is measured.. Master the concepts behind cache memory, virtual memory, memory segmentation, paging and address translation.. and Disk Scheduling. Eighth Edition. By William Stallings. Operating Systems:. Internals and Design Principles. Categories of I/O Devices. External devices that engage in I/O with computer systems can be grouped into three categories:.
