Web applications, also known as web apps, are applications that are accessed over the internet using a web browser. They are typically developed using a combination of web technologies such as HTML, CSS, and JavaScript, and are often hosted on a web server.


One of the key benefits of web applications is that they are platform-independent, meaning they can be accessed on any device with an internet connection and a web browser. This makes them a popular choice for businesses, as they can be used by employees and customers alike, regardless of the device they are using.


Another advantage of web applications is that they can be easily updated and maintained. Because they are hosted on a web server, updates can be made quickly and easily, without the need to install new software on each individual device.


Web applications are also often more cost-effective than traditional desktop applications, as they do not require expensive licensing fees or specialized hardware.


Overall, web applications offer a number of benefits, including platform independence, easy maintenance, and cost-effectiveness. These factors make them a popular choice for businesses and organizations looking to provide access to applications over the internet.

Web development is the study of developing a website for the Internet (World Wide Web) or an intranet (private network). Web development can range from developing a simple single static plain text page to complex web applications, electronic businesses and social networking services. A more comprehensive task list that Web development commonly refers to may include Web engineering, Web design, Web content development, client connectivity, client-side/server-side scripting, Web server and network security configuration, and e-commerce development. "Web development" among web professionals often refers to the main non-design aspects of creating Web sites: markup writing and coding. Web development can use content management systems (CMS) to make content changes easier and available with basic technical skills.
