A precise step by step guide to achieving a specific outcome. We all use algorithms all the time but often don’t recognise them as such. The order we dress and wash could be described as a getting up [..]

Logical reasoning is the systematic application of rules to problem solving and task completion. These rules could be mathematical, logical, programming, grammatical, engineering, scientific, story co [..]

Debugging is the art of fixing or correcting algorithms or programming code. Ultimately in all areas of learning we want pupils to become independent and to find solutions to errors themselves. Comput [..]

Decomposing sometimes called factoring is breaking a problem into smaller manageable chunks that can be solved separately. In a software company this allows different teams of people to work on the sa [..]

A sequence is a set of actions or events that must be carried out in the same order every time. Along with selection and repetition it is one of the three basic logical structures used by algorithms a [..]

Selection is about choice. It is the place where an algorithm or program branches in different directions. Choice can be made in many ways including by the user as in a quiz program (if answer is corr [..]

(loop) Repetition refers to sections of code or algorithmic instructions that are repeated. There are different types of loop. The most basic is where a set of instructions in repeated a set number of [..]

Variables are programming structures that can change or be changed. A simple adventure game may have hitpoints as a variable, as the game progresses the number of hitpoints can be adapted by the progr [..]

Adding data into a program or computer system. A user could input information to steer a sprite or type an answer using a keyboard or mouse. A more modern input might be voice activated or via a touch [..]

Output is information provided by a program specifically for a user to perceive. It might be text on a screen, a beep through a speaker or a rumble on a hand held controller.
