UNIX systems

41.    How many disk operations are needed to fetch the i-node for afile with the path name

/usr/ast/courses/os/handout.t? Assume that the i-node for the root directory is in mem- ory, but nothing else along the path is in memory. Also assume that all directories fit in one disk block.

42.    In many UNIX systems, the i-nodes are kept at the start of the disk. An alternative de- sign is to allocate an i-node when a file is created and put the i-node at the start of the first block of the file. Discuss the pros and cons of this alternative.

43.    Write a program that reverses the bytes of a file, so that the last byte is now first and the first byte is now last. It must work with an arbitrarily long file, but try to make it reasonably efficient.
