Control Systems (sequences, sensors/subroutines)

What is a sequence in the context of algorithms?

• A random order of commands

• A list of commands in a logical order

• A single command

• An unordered set of tasks

What does the word "logical" imply in the context of a sequence?

• It must be random

• It must make sense

• It must be complex

• It must be simple

What happens if the order of a sequence is not logical?

• The computer will process it faster

• The computer will not be able to process the algorithm

• The computer will ignore the sequence

• The computer will complete the task automatically

Why is it important for a sequence to be logical?

• To ensure the computer can process the algorithm

• To make the sequence more complex

• To confuse the computer

• To make the sequence longer

Which type of sensor can trigger a burglar alarm?

• Heat sensor

• Smoke sensor

• Motion sensor

• Light sensor

What can heat sensors automate in a home?

• Lighting system

• Heating system

• Security system

• Fire alarm system

What do smoke sensors detect?

• Movement

• Temperature

• Smoke from a fire

• Darkness

What can light/motion sensors automatically switch on?

• Heating system

• Security cameras

• Lights

• Smoke alarms

What can motion sensors trigger besides a burglar alarm?

• Fire alarm

• Automatic door

• Heating system

• Light system

What is the role of a sub routine in a larger program?

• To act as the main program

• To perform a specific task repeatedly

• To manage user data

• To design the user interface
