Every sheet in February 1979
The same date always regenerates the same five questions, so a sheet you print today is the sheet a classmate prints tomorrow.
- 1st February 1979State one function carried out by the operating system of a computer.
- 2nd February 1979In computational thinking, what is meant by the term 'decomposition'?
- 3rd February 1979Given A = 1 and B = 1, state the value of A AND B.
- 4th February 1979Convert the denary number 39 to an 8-bit binary number, showing your working.
- 5th February 1979Define a peer-to-peer network.
- 6th February 1979Name the translator used for assembly language and describe how it differs from a compiler.
- 7th February 1979Convert the denary number 5 to a 4-bit binary number.
- 8th February 1979A CPU has a clock speed of 4.0 GHz. Calculate how many clock cycles it completes in 2 seconds.
- 9th February 1979A simple cipher shifts every letter 2 places forward in the alphabet, wrapping around so Y becomes A and Z becomes B. Encrypt the plaintext CAT using this cipher.
- 10th February 1979Explain what happens if a program tries to read index 5 of an array declared with 5 elements.
- 11th February 1979A mono sound clip has a sample rate of 4000 Hz and lasts 2 seconds. Calculate the total number of samples taken.

- 13th February 1979State one reason a small business might choose to use open source software instead of proprietary (closed source) software.
- 14th February 1979A FOR loop runs: total = 0, FOR i = 1 TO 4, total = total + i, NEXT i. State the value of total after the loop finishes.
- 15th February 1979Give one specific way this code could be refined without changing what it does: a = 5, b = 3, c = a + b, PRINT c
- 16th February 1979State the typical maximum capacity of a single-layer DVD.
- 17th February 1979Define the term protocol.
- 18th February 1979State what is meant by a syntax error.

- 20th February 1979What type of utility software reorganises files on a hard disk so fragmented parts are stored closer together?

- 25th February 1979Explain the purpose of a breakpoint.
- 26th February 1979Convert the 4-bit binary number 1101 to denary.
- 27th February 1979Two CPUs are compared for a task optimised for multiple cores: CPU A has 2 cores at 4.2 GHz; CPU B has 6 cores at 3.0 GHz. Explain which CPU is likely to perform better for this task.
- 28th February 1979State why an organisation might employ penetration testers to test its network.
