Virtual Memory

A computer has a page size of 1024 words, 132 virtual pages and only 6 page frames. Initially, the memory is empty. A program references the following virtual addresses: 0, 6001, 4000, 2047, 1075, 6250, 1009, 14333, 4099, 3800, 1024, 7231, 5101, AND 19000. Considering that the memory management algorithm in place is the LRU. Which references cause a page fault? Justify your answer by showing the mapping of pages to frames step by step. hide problem

Omega Network

Given the following Omega network that allows 8 CPUs (P0 through P7) to access 8 memory modules (M0 through M7): See attached file for full problem description. (a) Show how the following connections through the network are achieved (explain how each switch must be set). (1) P0 -> M5 (2) P4 -> M2 (3) P7 -> M3 (b) Can these connections occur simultaneously or do they conflict? Explain.

1 processor/IO bound programs

If run by itself, an I/O bound program spends more time waiting for I/O than using the processor and vice versa for the processor-bound. Given a short-term scheduling algorithm favoring those programs that have used little processor time in the recent past. Explain why this algorithm favors I/O bound programs and yet does not permanently deny processor time to processor bound programs.

Finding ClipArt

Prepare and save documents using word processing software. The ClipArt Directory: Microsoft provides an abundance of clip art images, icons, backgrounds, and wizards to help you create professional looking Web pages. At times, however, you may want to venture onto the Internet to find more resources. Many sites exist online for you to download free clip art and other Web page resources. Explore the Internet to discover at least two additional sites (other than Microsoft) that offer clipart, either free or for a price. If you have real world or hobby experience with clipart sites, include them as part of the minimum two sites and write about the reason(s) why you use these sites. If y... click for more
