Answer:
Join
Explanation:
Five basic set operators in relational algebra are as follows:
- Selection - tuple selection
- Projection - extract columns
- Cartesian product - cross product of relations
- Set union - union of two relations
- Set difference - minus operation on two relations
As we can see, Join is not part of the basic set operations but it is implemented using the Cartesian Product operator.
Hey there!
Memory (RAM) is considered to be hardware since it is a physical component that makes up the computer and is accessed through the CPU rather than internal code that makes the computer run (which is software). Therefore, if you are having issues with the memory, it is likely a problem with a memory chip, making it a hardware issue.
Hope this helped you out! :-)
