Algorithm Logical reasoning Program Debugging Logic Selection Sequence Repetition Variables Data representation

Algorithm A 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". Program A set instructions that are understand by the computer and carried out Debugging Finding and fixing mistakes in programs Most programs don’t work as they should first time round. Mistakes in programs are called ‘bugs’ and finding and fixing them is ‘debugging’. Selection Instructions that are carried out if a particular condition is met Sequence Instructions that are carried out in order Repetition Instructions that are repeated – a certain number of times, until a condition is met or until the program is stopped Variables Numbers and text stored and referred to in programs e.g. name = “Bob” Data representation Data can be stored and used by a computer as text, images, sound or video Logic Using the values of true and false alongside operations such as AND, OR and NOT Computing terms

Algorithm Method for solving a problem Program Series of instructions Debug Finding and fixing mistakes in programs Logic True/False, AND, OR, NOT etc. Selection Instructions carried out if a condition is met Sequence Instructions carried out in order Repetition Repeat set of instructions Variable Values stored to refer to later
