Q23

A file system with a one-level directory structure is implemented on a disk with disk block size of $4K$ bytes. The disk is used as follows:

$$\begin{array}{|l|}\hline \text{Disk-block 0} & & \text{File Allocation Table, consisting of one 8-bit } \\ \text{} && \text{entry per data block, representing the data } \\ \text{} && \text{block address of the next data block in the file} \\ \hline \text{Disk-block 1} & & \text{Directory, with one 32 bit entry per file:} \\\hline \text{Disk-block 2} & & \text{Data-block 1;} \\ \hline \text{Disk-block 3} & & \text{Data-block 2; etc.} \\ \hline\end{array}$$
