Q$\mathrm{.}4)(25$pts$)$ The file $F$ which is $9,500$ bytes long, has been opened by process $P$ for

write. The file system uses UNIX$-$like index structures $($inodes$),$ with $10$ direct data block

pointers and three indirect pointers for single, double and triple indirection. The block

size of the file system is $1,000$ bytes and the size of a block pointer is $10$ bytes. Assume

that the inode structure for file $F$ is in memory but none of its data blocks are.

Process P makes a write$()$ call to to the file to append $800$ new bvtes to the end of the

file.

a$)$ How many blocks will be updated on disk to satisfy this request? Explain $(10$pts$)$

b$)$ What is the maximum file size in this system? Explain$(10$pts$)$

c$)$ Assume that text files have sizes in the range $1K-16K$ in this system. List someI

advantages and disadvantages, if the disk block size was changed to $16K.(5$pts$)$
