48. Consider an index-based file system with the inode containing 64 indexes, 1 indirect index pointing to a disk block containing an array of direct indexes, and 1 2-level index in the usual way . Assume that each index takes 4 bytes. i) What is the maximum file size under this arrangement, if a disk block is 1024 bytes? Explain how do you compute this maximum size ii) How many disk accesses does it take to rea at location 3000321 within a file, assuming no caching. d one disk block
