Consider a file system on a disk that has both logical and physical block sizes of 512 bytes and the physical addresses are 32-bits wide. Assume that the information about each file is already in memory. For exercises 3-5, 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.) Assume the logical address is the byte in the file and the physical address is the physical block number. 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? 3) Contiguous 4) Linked Allocation (assume we know the pointer to the first block) 5) UFS Indexed (assume we have the inode pointer structure cached in memory and the address block address needs 32-bits)

Consider a direct-mapped cache with 216 words in main memory. the cache has 16 blocks of 8 words each. it is a word-addressable computer (rather than a byte-addressable computer which we normally discuss). (a) how many blocks of main memory are there? (b) what is the format of a memory address as seen by the cache, that is, what are the sizes of the tag, cache block, and block offset fields (if they apply)? (c) to which cache block will the memory reference db6316 map?
