1Multiple choice1 markLow and High Level Languages Swap Remove

A software company writes its application programs in a high-level language.

Identify the main reason a high-level language is used for most application programs.

[1 mark]
  • AIt gives the programmer direct control of the hardware
  • BIt is easier to learn, write and debug
  • CIt produces smaller executable code
  • DIt runs more quickly than a low-level language
Mark scheme
  • B It is easier to learn, write and debug (1)
  • The only correct answer is B. The correct answer is easier to learn, write and debug.
  • A is not correct because direct control of the hardware is a reason for using a low-level language
  • C is not correct because a low-level language produces smaller executable code
  • D is not correct because low-level programs run more quickly than high-level programs
Example answers and how they were marked
Full marks1/1

B It is easier to learn, write and debug

Why: Correct option: high-level languages look like English, so programs are quicker to write and easier to debug (1).

No marks0/1

C It produces smaller executable code

Why: Near miss: smaller executable code is a feature of low-level languages, so no mark is awarded.

No marks0/1

A It gives the programmer direct control of the hardware

Why: Misconception: direct control of hardware is a purpose of low-level languages, not high-level, so no mark.

2Short recall1 markTranslators Swap Remove

An interpreter translates high-level code.

State what happens to the translation of a program when an interpreter finds a syntax error.

[1 mark]
Mark scheme

Award one mark for any of the following:

  • Translation/execution stops (when the error is found) / the rest of the program is not translated/executed (1)

Allow stops/terminates/halts when the error is found

Do not accept shows/displays an error message on its own

Do not accept the whole program is translated and errors are reported at the end

Do not accept translates line by line on its own

Example answers and how they were marked
Full marks1/1

The translation stops as soon as the error is found, so the rest of the program is not translated.

Why: Translation stops when the error is found (1).

No marks0/1

An error message is displayed.

Why: Only an error message; it does not say translation stops, and the scheme does not accept a displayed error message on its own.

No marks0/1

The whole program is translated and all the errors are reported at the end.

Why: Describes a compiler; the scheme does not accept errors being reported at the end of translating the whole program.
