Hi All,

I am referring to the link: http://www.tux4u.nl/freedocs/unix/draw/inode.pdf

I am confused on parts: 1 > 12 direct block pointers 2 > 1 single indirect block pointer 3 > 1 double indirect block pointer 4 > 1 triple indirect block pointer

• Now the diagram says that each pointer is 32/64 bits. [Query]: Why and how are these values inferred? I mean why specifically have only 32 or 64 bit pointers?

• The diagram says, One data block{8 KB} for each pointer {4 bytes/8 bytes} [Query]: How does this actually work out? i.e. 8*1024 bytes / 8 bytes = 1024 bytes? What is the logic behind having a 8 bytes pointer for 8KB block?
