IGCSE Computer Science - Algorithms

Flashcards covering key vocabulary and concepts related to algorithms as discussed in the IGCSE Computer Science lecture notes.

Algorithm

A precise set of rules or instructions to solve a specific problem or task.

Structure Diagram

A visual representation showing hierarchical top-down design, dividing problems into sub-problems.

Flowchart

A visual tool using shapes to represent functions, showing input/output, processes, decisions, and flow of control.

Pseudocode

A text-based tool that uses short English statements to describe an algorithm, offering structured yet flexible writing.

Input

The data given to the algorithm for processing.

Output

The data produced by the algorithm after processing the input.

Flow of Control

The order in which individual statements, instructions, or function calls are executed in a program.

Subroutine

A set of instructions designed to perform a frequently used operation, can be called from multiple places in a program.

Count

A variable commonly used to keep track of the number of iterations or items processed in algorithms.

Grade

An assignment of quality received based on performance measures, often categorized as A, B, C, D, E, F.
