1) Assume that UHCL stores student records in blocks of 512 bytes. The system uses a block pointer which 10 bytes long and a record pointer is also 10 bytes long. There are 40,000 student records. A student record has the following layout: Student(SSN, LastName, FirstName, Street, City, State, Zip, Phone, DateOfBirth, Gender, Major) 10 Bytes 10 Bytes 9 Bytes10 Bytes 9 Bytes 4 Bytes 20 Bytes 20 Bytes 2 Bytes10 Bytes 1 Byte A) Assume that the UHCL Student file uses an unspanned organization. That is, no record is may split across disk blocks. Ignore any overhead. Show work for each question below. It is worth a total of 15 points. a) Calculate the record size in bytes. b) Calculate the blocking factor of the data file c) Calculate the number of file blocks
