Definition

When analysing an algorithm, identify the data it takes in (inputs), the results it produces (outputs), what it is designed to do (purpose) and how it connects to other subroutines.

Example: Inputs: array of marks. Output: the average. Purpose: calculate the class mean.

Check this one: Not found word-for-word in the supplied syllabus, specifications, marking guidelines or notes; the definition is standard computing knowledge, so check it against your class notes.

Where you'll use it in the test

Syllabus area: Y11 Programming Fundamentals.

Question types it can appear in

Code reading: Code or algorithm reading: interpret a fragment and state its output or purpose.
Pseudocode: Use it correctly in the exam pseudocode editor.
Short answer: State what the algorithm does

How to use it

A model sentence

General advice, built from the definition and example above

“When analysing an algorithm, identify the data it takes in (inputs), the results it produces (outputs), what it is designed to do (purpose) and how it connects to other subroutines.” Then apply it: Inputs: array of marks. Output: the average. Purpose: calculate the class mean.

In a short answer, give the definition in your own words first, then tie it to the situation in the question. Do not copy the example above unless it fits the scenario.
