A Level Control Systems Quiz 1

15 Questions

Quiz Description

Here in this quiz, we will be looking at control systems. Under control systems, we have the open-loop control system concepts, closed-loop control system, feedback, and a lot more. After going through this quiz, you will be able to answer standard control systems questions during the exams.

A control system can be defined as an organization of parts that influences a system when connected. For efficiency, accuracy, and reliability, automated control systems are used. Let’s take the example of controlling the temperature of a room. A temperature sensor is used to detect temperature changes, sends the data to the controller which then sends a command to a fan that cools the temperature. One important component of a control system is a microprocessor. A microprocessor is an integrated computer circuit that performs the functions of a CPU such as data processing and calculations. Also, control systems could have sensors (input devices that measure physical quantities).

Control systems are very important as far as the industrial application of computers is concerned. Do you wish to learn more about control systems? Go ahead and answer this computer science quiz. Good luck.
