Consider a file system that uses a structure similar to an i-node with the following differences. If the file size is less than 100 bytes, the data is stored directly in the i-node. If it is larger, there are 8 direct links (point to a data block), 2 single-indirect links, 1-double indirect links and 1 triple indirect link. The underlying storage uses 4K block and 64bit addressing (i.e., use 64bit integer to index a disk block). a. What is the largest file size that can be indexed in this system? b. How many blocks (including index blocks) are needed to address a file of size 500 bytes, 50K bytes, and 5M bytes
