Every sheet in March 1996
The same date always regenerates the same five questions, so a sheet you print today is the sheet a classmate prints tomorrow.
- 1st March 1996An 8-bit register stores the value 01100000 (denary 96). State the resulting 8-bit binary value after a left shift by 1 place, and state whether an overflow occurs.
- 2nd March 1996Which CPU register holds the address of the next instruction to be fetched?
- 3rd March 1996Distinguish between the network security threats known as phishing and pharming.

- 5th March 1996A row of pixels is encoded using run-length encoding as: 3W 4B 3W. State the original row of pixels it represents.
- 6th March 1996A photo file is 3.5 MB in size. Calculate its size in kilobytes (KB). Use 1 MB = 1000 KB.
- 7th March 1996A streaming company records which shows each user watches and uses this to recommend similar shows. Explain one ethical concern this could raise, even if the company only uses the data to improve recommendations.
- 8th March 1996State the most appropriate data type for storing a person's shoe size if only whole sizes (e.g. 7, 8, 9) are allowed.

- 10th March 1996Give one example of an optical secondary storage device.
- 11th March 1996A 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?
