Authentication: The process of verifying the identity of a user, device, or system attempting to access a particular resource or service. It involves confirming the validity of supplied credentials, such as a username and password, using various methods like biometrics, tokens, or digital certificates. The purpose of authentication is to prevent unauthorized access and ensure that only authorized individuals or entities gain entry.
MVC: An acronym for Model-View-Controller, which is a design pattern commonly used in software development. It divides an application into three interconnected components: the model, which represents the data and business logic; the view, which renders the user interface; and the controller, which handles user input and initiates actions. MVC improves code organization, facilitates code reusability, and enables easier maintenance and testing of applications.
User Authorization: The process of granting or denying access to specific resources or functionalities within a system based on the user's authenticated identity and permissions. It involves determining the level of access rights or privileges that an authenticated user should have. User authorization ensures that only authorized individuals or roles can perform certain actions or view restricted information, enhancing security and preventing unauthorized activities.
