GCSE - Flowcharts

Define the term ‘Algorithm’

• The process of filtering out the characteristics of problems that are not needed in order to concentrate on those that are needed

• An algorithm is a set of steps/instructions needed to complete a software task.

• The process of breaking down a complex problem into a series of more manageable problems

• Identifying patterns

In a flowchart, what is the purpose of an arrow?

• To show where the inputs and outputs occur

• To show the flow from one component to the next

• To show where iteration happens

Which of these is the correct definition of sequence?

• Sequence are glittery objects sewn onto a dancing dress.

• Sequence means that the same statements are repeated in the program.

• Sequence means that program statements are set out one after another

• Making a decision, the outcome of which will determine what happens next

Which of these is the correct definition of iteration?

• Repeating an action until a defined outcome is achieved, which enables the program to move onto the next steps

• Making a decision, the outcome of which will determine what happens next

• Actions must be done in the correct order so the desired outcome is achieved

• Error identification and resolution
