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

A compiler translates a whole program in one go before it is run.

Name the type of code that a compiler produces.

[1 mark]

Do not accept source code.

Do not accept high-level code.

Example answers and how they were marked
Full marks1/1

Object code.

Why: Object code is named as the code a compiler produces (1).

No marks0/1

High-level code.

Why: Near-miss: this is the input to the compiler, not the code it produces; not accepted.
