- A particular activity or task is expressed as a series of individual steps or instructions that can be executed by the computer.- Like a recipe, a sequence of programming instructions specifies the behavior or action that should be produced.

- Loops are a mechanism for running the same sequence multiple times.

- The sequences of instructions happening at the same time.

- One thing causing another thing to happen- An essential component of interactive media.

- The ability to make decisions based on certain conditions, which supports the expression of multiple outcomes.

- Provide support for mathematical, logical, and string expressions- Enabling the programmer to perform numeric and string manipulations.

- Data involves storing, retrieving, and updating values.- Keeping score in a game is a frequent motivator for young designers to explore variables.

- Break down the complex problems into smaller, simpler and more manageable part problems.- Then, focusing on solving each part of problem.

- Focusing on the information that is relevant and important. - It involves separating core information from extraneous details.- Pulling out the important details- Identifying principles that apply to other problems/situations

- A sequence of steps for solving a problem- A plan, a set of step-by-step instructions to solve a problem. - If you can tie shoelaces, make a cup of tea, get dressed or prepare a meal then you already know how to follow an algorithm.

- The routine process of identifying and fixing the error.- Detecting, moving and fixing "bugs" in algorithms and processes to make them behave as expected.

- Repeat design processes to refine solutions, until the ideal result is achieved.

- Also referred to as pattern recognition. - Taking a solution (or part of a solution) to a problem and generalise it so it can be applied to other similar problems and tasks.
