IB Digital Society 3.2C Representing Algorithms Key Definitions

A finite sequence of clear, unambiguous steps that takes an input and follows a set procedure to produce an output or solve a problem.

A diagram that represents an algorithm using standard shapes joined by arrows, so the flow of steps and decisions can be followed at a glance.

A structured, code-like way of writing an algorithm in plain language, precise enough to show the logic but not tied to any real programming language.

A variable is a memory storage location that holds the values that the algorithm needs, which may change during runtime.
