A file hаs r = 25,000 STUDENT recоrds оf fixed length. Eаch recоrd hаs the following fields: Name (65 bytes), Ssn (9 bytes), Address (85 bytes), PHONE (20 bytes), Birth_date (8 bytes), Sex (1 byte), Major_dept_code (4 bytes), Minor_dept_code (4 bytes), Class_code (4 bytes, integer), and Degree_program (46 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: show your computation completely to get the whole points for each section).Calculate the record size R in bytes.Calculate the blocking factor bfr and 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 and using the primary index.
