A file hаs r = 42,000 STUDENT recоrds оf fixed length. Eаch recоrd hаs the following fields: Name (55 bytes), Ssn (9 bytes), Address (45 bytes), PHONE (8 bytes), Birth_date (8 bytes), Sex (1 byte), Major_dept_code (6 bytes), Minor_dept_code (6 bytes), Class_code (4 bytes, integer), and Degree_program (48 bytes), an additional byte is used as a deletion marker. Consider the block size B=512 bytes, and blocking factor Bfr = B div R (R is the record size). Also, for an index on the SSN field, assume the field size Vssn = 32 bytes, assume the record pointer size Pr = 16 bytes. (Note: Please show your computation completely to get the whole points for each section, also use the rounding of numbers correctly when using the floor and ceiling operations for rounding).Calculate the record size R in bytes.Calculate the blocking factor bfr.Calculate the number of file blocks b, assuming an unspanned organization.Calculate the number of block accesses needed to search and retrieve a record from the file, given its Ssn value, using the primary index, and using a Binary search method.Please note: show all the steps of computations to get the full points, as only providing the answer will not get any points.
