Take off P1 Create a dynamic memory partitioning algorithm, then circle where P3 is located using the following algorithm: a. Worst-Fit b. Best-Fit c. First-FitComputer Architecture Assume a task is divided into four equal-sized segmrnts and that the system builds an eight-entry page descriptor table for each segment. Thus, the system has a combination of segmentation and paging. Assume also that the page size is 2 Kbytes. a) What is the maximum size of each segment? b) What is the maximum logical address space for the task? c) Assume that an element in physical location 00021ABC is accessed by this task. What is the format of the logical address that the task generates for it?
- How does the global page-replacement strategy ensure sufficient free memory to satisfy new requests?OPERATING SYSTEMS Give two reasons why caches are useful.What problems do they solve?What problems do they cause? If a cache can be made as large as the device for which it is caching (for instance, a cache as large as a disk),why not make it that large and eliminate the device?Caches are utilized to benefit from "spatial locality" and "temporal locality" in order to increase performance. What benefits do caches get from these two phenomena?
- Compare the allocation strategies for indexed file space, linked allocation, and contiguous allocation of disk space.The type of server in two-tier architectures which provides the data to client stored on disk pages is calledHow do you implement caching strategies to optimize the performance of a web application, and what are the considerations for cache expiration and invalidation?
