OPERATING SYSTEMS 1. Given six memory partitions of 100 MB, 170 MB, 40 MB, 205 MB, 300 MB, and 185 MB (in order), how would the first‐fit, best‐fit, and worst‐fit algorithms place processes of size 200 MB, 15 MB, 185 MB, 75 MB, 175 MB, and 80 MB (in order)? Indicate which, if any, requests cannot be satisfied. Comment on how efficiently each of the algorithms manages memory in terms of fragmentation. 2. Consider a logical address space of 64...

Suppose that we have a computer system using 32-bit logical address and 46–bit physical address. It also uses paging for memory management with a single-level page table organization. The page size is 4K bytes and each page table entry is 32 bits or 4 bytes in size. Calculate the number of bits in each field in the logical address, the size in bytes of the page table, and the number of frames.
Exercise 6.4.1: Parameters of paging and segmentation. A memory system employs both paging and segmentation: The logical address size is 32 bits. Page size is 512 words. The segment table contains 213 entries. (a) What is the size of w? (b) What is the maximum number of pages per segment?
