1Multiple choice1 markLow and High Level Languages Swap Remove

Programming languages can be either high-level or low-level.

Identify the low-level programming language.

[1 mark]
  • AAssembly language
  • BC#
  • CJava
  • DPython
Mark scheme
  • A Assembly language (1)
  • The only correct answer is A. The correct answer is assembly language.
  • B is not correct because C# is a high-level language
  • C is not correct because Java is a high-level language
  • D is not correct because Python is a high-level language
Example answers and how they were marked
Full marks1/1

A Assembly language

Why: Correct option: assembly language uses mnemonics and is a low-level language (1).

No marks0/1

D Python

Why: Near miss: Python is a high-level language, so no mark is awarded.

No marks0/1

C Java

Why: Misconception: Java is a high-level language because it uses statements that look like English, so no mark.

2Short recall1 markTranslators Swap Remove

A compiler translates programs written in a high-level language.

State how much of a program a compiler translates before the program is run.

[1 mark]
Mark scheme

Award one mark for:

  • The whole program (before it is run) (1)

Allow all of the code/the entire program/the whole program in one go

Do not accept one line/statement at a time or each line as it is executed

Do not accept translating only the lines that contain errors

Example answers and how they were marked
Full marks1/1

The whole program, before it is run.

Why: Whole program translated before it is run (1).

No marks0/1

It translates the program one line at a time.

Why: Describes an interpreter; the scheme does not accept line-by-line translation.

No marks0/1

It translates only the lines that contain errors.

Why: Not a compiler behaviour; the scheme does not accept translating only error lines.

3Describe2 marksLow and High Level Languages Swap Remove

A program can be written in a high-level language such as Python.

Describe one characteristic of a high-level programming language.

[2 marks]
Mark scheme

Award up to two marks for a linked description such as:

  • Statements are written using words/phrases that look like English or maths (1) so the code is easier to read/understand/write (1)
  • One statement is translated into several machine code instructions (1) so programs are shorter to write than in a low-level language (1)
  • High-level languages provide built-in data structures such as arrays/lists/records (1) so a collection of data items can be stored and accessed under one name (1)

Do not accept responses that only give a benefit or drawback, such as 'it is easier to learn', with no characteristic.

Do not accept 'it is easier than a low-level language' without saying what the characteristic is.

Example answers and how they were marked
Full marks2/2

Statements are written using words that look like English or maths so the program is easier to read and understand.

Why: Characteristic of the statements (1) with a linked development (1).

Some marks1/2

It has built-in data structures such as arrays.

Why: A correct characteristic (1) but no development of what it allows the programmer to do.

No marks0/2

It is easier to learn than a low-level language.

Why: Gives only a benefit compared with a low-level language; no characteristic of the language itself, so no mark.
