Assuming each block of a disk is 512 KB, and the system uses an in-memory file allocation table, use a series of diagrams to show how a system using contiguous allocation of disk blocks would perform the following operations: i. Store a 3 MB file named f1 ii. Store a 2 MB file named f2 ii. Store a 1 MB file named f3 iv.Delete the file f2 v. Store a 1 MB file named f4
