Is there not a reason why different directories on a disk are located in different spots? Here are some advantages of each potential outcome:

Compilers and assemblers are responsible for turning source files into files containing object code. First, the object files need to be linked together before they can be executed. Compilers have the potential to produce final executable files even in the absence of linking. What are some of the problems associated with using the second approach?

Requests are not usually uniformly distributed. For example, a cylinder containing the file system FAT or inodes can be expected to be accessed more frequently than a cylinder that only contains files. Suppose you know that 50 percent of the requests are for a small, fixed number of cylinders. a. Would any of the scheduling algorithms discussed in this chapter be particularly good for this case? Explain your answer. b. Propose a disk-scheduling algorithm that gives even better performance by taking advantage of this "hot spot" on the disk. c. File systems typically find data blocks via an indirection table, such as a FAT in DOS or inodes in UNIX. Describe one or more ways to take advantage of this indirection to improve the disk performance.
