August 1971 5-a-day

Every sheet in August 1971

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

  1. 1st August 1971A programmer wants any syntax error in their program to be reported before the program starts running at all. State whether a compiler or an interpreter behaves this way, and explain why.
  2. 2nd August 1971Give one reason why RAM on its own is not enough, and a computer also needs secondary storage.
  3. 3rd August 1971State the difference between HTTP and HTTPS, and give one situation where HTTPS is essential.
  4. 4th August 1971A password field requires between 6 and 12 characters. State two boundary data values that should be used to test this field.
  5. 5th August 1971A table called bookings has fields bookingId, customerName and eventDate. Write an SQL statement that deletes the booking with bookingId 45.
  6. 6th August 1971State one function carried out by the operating system of a computer.
  7. 7th August 1971In computational thinking, what is meant by the term 'decomposition'?
  8. 8th August 1971Given A = 1 and B = 1, state the value of A AND B.
  9. 9th August 1971Convert the denary number 39 to an 8-bit binary number, showing your working.
  10. 10th August 1971Define a peer-to-peer network.
  11. 11th August 1971State why a program written in a high level language must be translated.
  12. 12th August 1971Convert the denary number 5 to a 4-bit binary number.

  14. 14th August 1971A 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.
  15. 15th August 1971Describe what a nested loop does when it processes a 2D array.
