what is indirect inode addressing?
Homework Answers
Inode addressing is mainly used for unix file system. Every file contains an index node or inode which stores the informstion of the file like file permissions,ownerships etc.The contents of a files are stored in a collection of data blocks. The pointer inode which links the data blocks.
There are only fifteen pointers in inode,and the first twelve for direct addressing. Other three are used for indirect addressing.
1.single indirect pointer: the total file size that can be accessed through this block is 4 MB.
2.Double indirect pointer: it have other block
addresses as content.That is addressed of the actual data
blocks.
3. Triple indirect pointer: This indirect block
will contain a set of double indirect block numbers. Each double
indirect block will have a set of single indirect block numbers and
each indirect block will have a set of direct data block
numbers.

2.Use a loop instruction with indirect addressing to reverse the elements of an array in place. -Do not copy the elements to any other array. -Use the SIZEOF, TYPE, and LENGTHOF operators to make the program as flexible as possible if the array size and type should be changed in the future. -Use the XCHG instruction. -The array’s elements are: “B”, “A”, “D”, “C”, “F”, “E”, “H”, “G”. -The array’s elements after running the program should look like: A, B,...
