[Solved] 2 Suppose Directory Containing Given File Memory Already Along Fat Node Table None File Me Q37220065

2. Suppose that the directory containing a given file is in memory already, along with the FAT or the i-node table, but none of the file is in memory. Now suppose that a program opens the file and requests to read byte number 66,000. Assume that file blocks are 1 KB in size. a. How many disk accesses are needed to open the file and read in the desired byte if sequential file organization is used? Explain b. Repeat (a) for a system using a FAT c. Repeat (a) for a system using Unix-style i-nodes with 10 direct pointers d. What advantage does the i-node approach have when the number of file blocks is very large?
