Group 7

Question 1

It is the process of sampling signals that measure real-world physical conditions and converting the resulting samples into digital numeric values that can be manipulated by a computer.

Answer 1

DATA ACQUISITION

Question 2

It is a device, that senses a physical quantity and converts it into an analog quantity that can be measured electrically such as voltage, capacitance, inductance, and resistance.

Answer 2

SENSOR

Question 3

It is a part of a device or machine that helps it to achieve physical movements by converting energy, often electrical, air, or hydraulic, into mechanical force. Simply put, it is the component in any machine that enables movement.

Answer 3

ACTUATOR

Question 4
