Answer and Explanation:
a) Key for the relation courses is HS.
b) FD's are already minimal basis, as no attributes can be removed from the left side, right side is having only single attributes and none of the FD can be removed as given in the question.
c) By using the 3NF synthesis algorithm, the final set of relations obtained will be CT, HRC, HTR, HSR, CSG (FD'S are already proved to be minimal basis in part (b)). All the relations are in BCNF.

I believe it is b so I will just leave it at that
The answer is firewall. It is a network security device that observes inbound and outbound network traffic and chooses whether to allow or block specific traffic based on a well-defined set of security rules.

A firewall can be software, hardware, or even both.

The question to this problem says;
Question:
I am sorting data that is stored over a network connection. Based on the properties of that connection, it is extremely expensive to "swap" two elements. But looping over the elements and looking at their values is very inexpensive. I want to minimize swaps above all other factors. Choose the sorting algorithm we studied that will perform the best:
ANSWER
1. Merge Sort
Because merge sort uses additional memory instead of swapping the elements.
2. Merge Sort and Quick Sort both can be used with multi processor.
cheers i hope this helps !!!
