Triple-indirection capability?

I mean shoudn't they give the disk address size? 0 votes 0 votes MiNiPanda commented Oct 9, 2018 reply Follow Share The default block size is 4096 B in UNIX file and i guess they have assumed that we know it.. 0 votes 0 votes superak96 commented Oct 9, 2018 reply Follow Share Yea, i thought so. But taking 4096 Bytes as the block size, it gives the max file size for triple indirection to be around 262 Bytes. Now doesn't it make it too impractical as it amounts to a file size of 4 EXABYTES? 0 votes 0 votes MiNiPanda commented Oct 9, 2018 reply Follow Share How 262 Bytes? Shouldn't it be 211*212=8MB? (i.e. # of disk block addresses*size of 1 block) 0 votes 0 votes superak96 commented Oct 9, 2018 reply Follow Share Ohh sorry. I didn't copy the complete question it seems. Have now edited it! For triple indirection, it amounts to 262 . 0 votes 0 votes Please log in or register to add a comment.
