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.
- 1st November 1982In computational thinking, what is meant by the term 'decomposition'?
- 2nd November 1982Given A = 1 and B = 1, state the value of A AND B.
- 3rd November 1982Convert the denary number 39 to an 8-bit binary number, showing your working.
- 4th November 1982Define a peer-to-peer network.
- 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.
- 6th November 1982Convert the denary number 5 to a 4-bit binary number.
- 7th November 1982A CPU has a clock speed of 4.0 GHz. Calculate how many clock cycles it completes in 2 seconds.
- 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.
- 9th November 1982An array named temps holds 12 values. State the index of the first item and the index of the last item.
- 10th November 1982A mono sound clip has a sample rate of 4000 Hz and lasts 2 seconds. Calculate the total number of samples taken.
- 11th November 1982State the type of program that is typically stored in ROM.
- 12th November 1982State one reason a small business might choose to use open source software instead of proprietary (closed source) software.
- 13th November 1982A FOR loop runs: total = 0, FOR i = 1 TO 4, total = total + i, NEXT i. State the value of total after the loop finishes.
- 14th November 1982Give one specific way this code could be refined without changing what it does: a = 5, b = 3, c = a + b, PRINT c
- 15th November 1982State the typical maximum capacity of a single-layer DVD.
- 16th November 1982State the difference between HTTP and HTTPS, and give one situation where HTTPS is essential.
- 17th November 1982State what is meant by a syntax error.
- 18th November 1982A table called members has fields memberId, firstName, lastName and joinYear. Write an SQL statement that adds a new record with memberId 12, firstName 'Priya', lastName 'Shah' and joinYear 2026.
- 19th November 1982What type of utility software reorganises files on a hard disk so fragmented parts are stored closer together?
- 20th November 1982Calculate the maximum number of comparisons required by a binary search on a sorted list of 512 items.
- 21st November 1982Given P = 0 and Q = 1, state the value of P OR Q.
- 22nd November 1982Convert the hexadecimal number FF to an 8-bit binary number.
- 23rd November 1982A network administrator is connecting 10 computers in a server room. Calculate the number of cables needed for a full mesh topology, and state the number needed for a star topology with one central switch.
- 24th November 1982State why a program written in a high level language must be translated.
- 25th November 1982Convert the 4-bit binary number 1101 to denary.
- 26th November 1982Two 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.
