a. Calculate the record size R in bytes.

b. Calculate the blocking factor bfr and the number of file blocks b, assuming an

unspanned organization.

c. Calculate the average time it takes to find a record by doing a linear search on

the file if (i) the file blocks are stored contiguously, and double buffering is

used; (ii) the file blocks are not stored contiguously.

d. Assume that the file is ordered by SSN; calculate the time it takes to search for a

record given its SSN value, by doing a binary search.
