A web app is a software application that operates on a web server and is accessed through a web browser over a network, such as the internet or an intranet. What distinguishes web apps is their dynamic nature and ability to interact with users, update content without the need to refresh the page, and scale content based on user behavior and preferences. Typically, they use a combination of server-side scripts (like PHP and ASP) to handle the storage and retrieval of information, and client-side scripts (like HTML, JavaScript, and CSS) to present information to users.
