Which would make the light flash on and off correctly?

This flowchart...

• Never turns the TV on

• Turns on the TV and then immediately switches it off once

• Turns on the TV and then immediately switches it off forever

• Allows the user to watch an interesting programme

Give an advantage of control technology

• Robots are smarter than people

• If the computer malfunctions the system will not work

• Can operate 24 hours a day without taking a break.

• Expensive to develop and maintain

Why do we need arrows in flowcharts

• To show the direction the flowcharts is travelling in

• To show the flow of information

• To show the number of boxes in the flowcharts

• So we can see the links

What can we use algorithms for

• Brushing our teeth

• Baking a cake

• Building a tree house

• All of these
