1 (a) Give two reasons why a programmer would choose to write code in a low-level language. 1 2 (b) High-level languages require either an interpreter or a compiler to translate the program. The table below lists a number of statements about language translators. Tick (✔) to show which statements refer to interpreters and which refer to compilers. Statements Translates the source code into machine code all at once Produces an executable file in machine code Executes a high-level language program one instruction at a time Once translated, the translator does not need to be present for the program to run An executable file is produced Interpreter (✔) Compiler (✔)

  1. (a)Give two reasons why a programmer would choose to write code in a low-level language.[2]
  2. (b)High-level languages require either an interpreter or a compiler to translate the program. The table below lists a number of statements about language translators. Tick (✔) to show which statements refer to interpreters and which refer to compilers. Statements Translates the source code into machine code all at once Produces an executable file in machine code Executes a high-level language program one instruction at a time Once translated, the translator does not need to be present for the program to run An executable file is produced[5]

Mark scheme

Marking points from the official mark scheme (Oct/Nov 2016). The mark or mark type is shown in brackets.

  1. [2] (a) Any two from:
  2. direct access to computer processor / special hardware // machine dependent instructions
  3. uses up less memory
  4. can increase the speed of processing a program // executes instructions faster
  5. [5] (b) Translates the source code into machine code all at once: Compiler (✔)
  6. Produces an executable file in machine code: Compiler (✔)
  7. Executes a high-level language program one instruction at a time: Interpreter (✔)
  8. Once translated, the translator does not need to be present for the program to run: Compiler (✔)
  9. An executable file is produced: Compiler (✔)
