we want to design the i-node structure for the file system. we use one block (i.e., one sector) to fit the i-node structure. the disk sector/block size is 256 bytes. an i-node needs 8 words for file information such as the id of the file, size of the file, etc. each word is 4 bytes. among all the pointers that the i-node structure can accommodate, we use four pointers for single-indirect block pointers and two pointers for double-indirect blocks. the rest are used for direct block pointers. each pointer uses 4 bytes. what is the largest file size this i-node can create? show your calculations and result.
