Consider a file whose size varies between $4KB$ and $4MB$ during its lifetime. Which of the three allocation schemes $($contiguous$,$ linked and table$/$indexed$)$ will be most appropriate?

It has been suggested that efficiency could be improved and disk space saved by storing the data of a short file within the i$-$node. For the i$-$node of Fig. $4-13,$ how many bytes of data could be stored inside the i$-$node?
