March 2026 - GCSE Computer Science 5-a-day
Every GCSE Computer Science sheet published in March 2026, with answers. Systems, data representation, networks, algorithms and programming.
Every sheet in March 2026
The same date always regenerates the same five questions, so a sheet you print today is the sheet a classmate prints tomorrow.
- 1st March 2026State the difference between lossy and lossless compression.
- 2nd March 2026State the condition that must be met before a binary search can be used on an array.
- 3rd March 2026A 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.
- 4th March 2026Convert the hexadecimal number FF to an 8-bit binary number.
- 5th March 2026Which piece of network hardware connects a LAN to another network such as the internet, directing data packets based on IP address?
