Task $5$: Nested loop join

We have a table Student$($Studentno$,$ Name, Birthday, DepartmentNo$)$ that must be joined

with ExamReg$($Studentno$,$ Examno, Date, Status$).$ Student is stored with $47000$ records in

$800$ blocks and ExamReg is stored with $500000$ records in $12800$ blocks. We wish to use

nested for loop join, meaning that we for each block in one of the tables compare and check

whether Studentno is equal.

If we have $34$ blocks available in the buffer, how many blocks are read in total throughout the

join operation?
