"现代操作系统课件：Chapter3-Paging.ppt总结"

Chapter 3 of the modern operating systems course covers the topic of paging and virtual memory. The lecture delves into the concept of virtual memory, including virtual address, paging, address translation schemes, page tables, translation lookaside buffers, multi-level page tables, and inverted page tables. The lecturer, Zhang Yang, discusses the challenges of managing bloatware, such as running programs that are too large to fit in memory and supporting multiple programs running simultaneously. The need for virtual memory arises from the need to separate user logical memory from physical memory. The lecture explores potential solutions to these challenges, such as swapping and overlay. Overall, the content of the lecture provides a comprehensive overview of the concepts and mechanisms involved in managing virtual memory in modern operating systems.
