ASP stands for "Active Server Pages." It's a technology developed by Microsoft for creating dynamic web pages and web applications. With ASP, you can embed server-side scripts within HTML pages to generate dynamic content.
.NET stands for "Network Enabled Technology." It's a software development framework developed by Microsoft that provides a controlled environment for building and running applications.
.NET is a software framework developed by Microsoft that primarily runs on Microsoft Windows. It provides a large library of pre-coded solutions to common programming problems and a runtime environment for executing and managing applications.
A class in programming is like a blueprint for creating objects with specific properties and actions. It defines what an object can do and what data it can hold.
A function is like a mini-program within a bigger program. It's a set of instructions designed to do a specific job, like adding numbers together or formatting text.
