- 1Ethical, Legal, Cultural and Environmental Impact
State whether the source code of proprietary (closed source) software is normally available for the public to view.
- 2Network Protocols and Layers
A user reads the same email on a phone and a tablet, and deleting it on one deletes it on the other. Which protocol is in use and why?

Explain the purpose of a breakpoint.

Trace this algorithm with data = [4, 9, 2, 9, 7] and state the final output. total = 0; count = 0; for i = 0 to 4: if data[i] > 5 then total = total + data[i] and count = count + 1; next i; print(total, count).
