Explain how the inode maps to data block of a file.There are 13 block addresses in inode. The file descriptions – type of file, access rights, and owners, time stamps of the files, size, and pointers to data blocks – are contained in each inode.
The first 10 block addresses are called direct block addresses which are the data blocks for the first 10 in the file.
The 11th, 12th and 13th addresses are pointed to a one-level index block and two-level index block and three-level index blocks respectively.
