Hi,

I am quite sure that I am posting a question in the very wrong forum but I have to give a try. It's a question about UNIX theory. I don't have any clue of how to solve this question. If someone could kindly provide some good references or give me the formulas, it will be really helpful...Thanks for taking your time....

Consider the organization of a UNIX file as represented by the inode. Assume that there are 12 direct block pointers, and a singly, doubly, and triply indirect pointer in each inode. Further, assume that the system block size and the disk sector size are both 4K. Moreover, the disk block pointer is 32 bits, with 8 bits to identify the physical disk and 24 bits to identify the physical block within a disk.

- What is the maximum file size supported by this system?
- What is the maximum file system partition (that is, the number of addressable bytes) supported by this system?
- Assuming that the file inode is already in main memory, how many disk accesses are required to directly access the byte in position 13,423,956?

Thanks a lot...I really appreciate any kind of help!
