An $\text{ISAM}$ (indexed sequential) file consists of records of size $64$ bytes each, including key field of size $14$ bytes. An address of a disk block takes $2$ bytes. If the disk block size is $512$ bytes and there are $16K$ records, compute the size of the data and index areas in terms of number blocks. How many levels of $\text{tree}$ do you have for the index?
