Closed-loop control system: A feedback path is employed in closed-loop control system to measure the original system parameters such as pressure, speed, and so on. Here, the controller produces an error signal which initiates corrective action and energize the output device. The main characteristic of a closed-loop control system is that it can sense and measure the actual output of the system. Examples of closed-loop systems include cooling system in car, water level controller, tracking radar systems, and many others.

The assignment here is to write an app using a database named CIT321 with a collection named students; we will provide a CSV file of the data. You need to use Vue.js to display 2 pages. You should know that this assignment is similar, all too similar in fact, to the cars4sale2 example in the lecture notes for Vue.js 2. You should study that program first. If you figure out cars4sale2, then program 6 will be extremely straightforward. It is not my intent do drop a ton of new material here in the last few days of class.
