MVC stands for MODEL VIEW CONTROLLER. Model View Controller separates application logic from the presentation layer. It helps web pages to contain minimum scripting.
MODEL : It is used to represent data structures. Model classes constitute functions that help to insert, retrieve, and update information in the database.
CONTROLLER : It acts as an intermediary between the view, model, or any other resource to process HTTP requests. The Controller controls the whole application by URI.
VIEW : It represents the information that is being presented to the user. In CodeIgniter, a View could be a simple or complex webpage. The web page contains a header, footer, sidebar, etc. A view cannot be called directly.
