The same date always regenerates the same five questions, so a sheet you print today is the sheet a classmate prints tomorrow.
- 1st January 1994State the key difference between a procedure and a function.
- 2nd January 1994Give one example of an optical secondary storage device.
- 3rd January 1994A 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?
- 4th January 1994State the term used for realistic data that a program would be expected to handle during normal use.
- 5th January 1994Give one advantage of a relational database over a flat-file database.
- 6th January 1994State the difference between lossy and lossless compression.
- 7th January 1994State the condition that must be met before a binary search can be used on an array.
- 8th January 1994A logic circuit has inputs C and D. C feeds into a NOT gate; the output of the NOT gate and D feed into an OR gate, giving output Y. Write the Boolean expression for Y and state its value when C = 1 and D = 0.

- 14th January 1994State what the term malware means.
- 15th January 1994Explain what happens if a program tries to read index 5 of an array declared with 5 elements.
