November 1982 5-a-day

Every sheet in November 1982

The same date always regenerates the same five questions, so a sheet you print today is the sheet a classmate prints tomorrow.

  1. 1st November 1982In computational thinking, what is meant by the term 'decomposition'?
  2. 2nd November 1982Given A = 1 and B = 1, state the value of A AND B.
  3. 3rd November 1982Convert the denary number 39 to an 8-bit binary number, showing your working.
  4. 4th November 1982Define a peer-to-peer network.
  5. 5th November 1982A program compiles and runs but always outputs an average that is too small. State the type of error and explain why the translator did not report it.
  6. 6th November 1982Convert the denary number 5 to a 4-bit binary number.
  7. 7th November 1982A CPU has a clock speed of 4.0 GHz. Calculate how many clock cycles it completes in 2 seconds.
  8. 8th November 1982A 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.
  9. 9th November 1982An array named temps holds 12 values. State the index of the first item and the index of the last item.
  10. 10th November 1982A mono sound clip has a sample rate of 4000 Hz and lasts 2 seconds. Calculate the total number of samples taken.
