- 1—Revision notes for Chapter 1
- 2What is an algorithm?An algorithm is a step by step set of instruction solving a problem that can be carried out by a human or a computer.
- 3What is a decision?A decision is when a question is asked(as in selection) the answer will lead to one or more different alternative actions.
- 4What is a process?An action that is taken, sometimes from the result of a decision, in order to achieve a desired outcome.
- 5What is a variable?A container which is used to store values such as the number of attempts
- 6What is a flow diagram?A flow diagram are used to to represent algorithms visually, using symbols that are connected by arrows to show the flow or the diagram and the order.
- 7What is this processes use for in flow diagrams?This represents the start or end of the flow diagram.
- 8What is an "input" and "output"?"Input is indicating that the user is going to input some information. "Output" indicates that a output message will print on the screen.
- 9What does iteration mean?A single run through of a set of instructions or a loop.
- 10What is the symbol of a decision/selection in a flow chart?A diamond shape
- 11What is the symbol for an action/process for a flow chart?A rectangle.
