• To calculate the cost of production

• To show the aesthetic design of a product

Which of the following is a common input device in a system?

• LED

• Motor

• Sensor

• Speaker

In a systems approach, what is the role of a process block?

• To store data

• To convert inputs into outputs

• To display information

• To power the system

Which of the following is an example of an output device?

• Microcontroller

• Buzzer

• Resistor

What is the function of feedback in a system?

• To increase the speed of the system

• To provide information about the output to adjust the input

• To reduce the cost of production

• To enhance the aesthetic appeal

Which of the following best describes a closed-loop system?

• A system with no feedback

• A system that operates manually
