Consider a fixed partitioning scheme with equal-size partitions of 2¹6 bytes and a total main memory size of 224 bytes. A process table is maintained that includes a pointer to a partition for each resident process. How many bits are required for the pointer?

Consider a file system on a disk that has both logical and physical block sizes of 512 bytes. Assume that the information about each file is al ready in memory. For each of the three allocation strategies (contiguous, linked, and indexed), answer these questions: a. How is the logical-to-physical address mapping accomplished in this system? (For the indexed allocation, assume that a file is always less than 512 blocks long.) b. If we are currently at logical block 10 (the last block accessed was block 10) and want to access logical block 4, how many physical blocks must be read from the disk

Consider a file system that uses indexed allocation with a maximum of one index node per file. Suppose the index node occupies 4096 bytes, that each block pointer occupies 4 bytes. Ignore the metadata associated with the file that is usually contained in the index node. How large should a block be (in bytes) so that this scheme is able to completely access files on a 1 GB file system?

Consider a memory of size 8KB (8192 bytes) that allows dynamic, variable sized partitioning among processes and uses a linked list to keep track of free spaces (hereafter referred to as the free list) in the memory at any given time. Assume that there are 6 processes and assume that their memory size requirements (in bytes) are as given below: Р1: 500, Р2: 600, Р3: 1300, Р4: 2000, Р5: 100, Р6: 200 Assume that the initial state of the free list is as shown below (BA is the base address and Sz is the size of each free space): ВА: 0; Sz: 1100 — ВА: 1200; Sz: 600 > BА: 2000; Sz: 1800> ВА: 6000%; Sz 400
