AlgorithmA precise method for solving a given problem A sequence of instructions, or a set of rules, for performing a specific task Logical reasoning Being able to explain cause and effect, rather than randomly guess without reasoning. It includes predicting what will happen as a result of running a program.e.g. "If the robot turns right four times (through a right angle), it will be facing the same way as it started". ProgramA set instructions that are understand by the computer and carried out DebuggingFinding and fixing mistakes in programsMost programs don’t work as they should first time round. Mistakes in programs are called ‘bugs’ and finding and fixing them is ‘debugging’.

SelectionInstructions that are carried out if a particular condition is metSequenceInstructions that are carried out in orderRepetitionInstructions that are repeated – a certain number of times, until a condition is met or until the program is stopped VariablesNumbers and text stored and referred to in programs e.g. name = “Bob” Data representationData can be stored and used by a computer as text, images, sound or video LogicUsing the values of true and false alongside operations such as AND, OR and NOT
