What is the definition of "Subsystem"?

• the interconnected parts of a system that can be classified as inputs, outputs and processes

• the small sections of a push button system

• the tiny sections of outputs that control an even smaller system

• the matching parts of a small system that can be linked to inputs, processes and outputs

What is an example of an input?

• Sound

• LED light

• Microcontroller

• Push button

There are two different types of input sensors, these are called digital and analogue but what one is used for measure a quantity?

• Analogue Sensor

• Digital Sensor

What type of sensor can detect a yes/no situation like a button being pressed?

• Digital Sensor

• Analogue Sensor

An Integrated Circuit is commonly known as...

• A microchip

• A microcontroller

• A process

• An electrical movement

What is an example of an output device?

• Button

• Buzzer

• Temperature

• Switch

To show how the components work, we draw a ______________ to clearly show a simple way of breaking down the microcontroller task by showing the key steps involved.

Microcontrollers are programmable devices that offers a designers the change to enhance the function of a product, but what products could they be used for?

• Counting - keeping track of scores in a sports game and displaying them on a electronic board

• Switching - switching on a streetlamp when the light level falls

• Timing - security light for a period of time after movement is detected

• Noise - being turned on when the noise level is too loud and being turned off when the noise level is low

What does feedback do in a control system?

• It improves the control function of the sytem

• It creates white noise so that the system is louder

• It makes the system work slower so that it is easier to control

• It improves the colour of the system so that it is less boring

Electronic systems all consist of.. what and in what correct order?

• Input, output, process

• Process, input, output

• Input, process, output

• Output, input, process
