Understanding the Basics of Web Applications
A web application is a software application that runs on a web server and is accessed through a web browser. Unlike traditional desktop applications that are installed on a local machine, web applications are accessed over the internet and are designed to be platform-independent. This means that they can be accessed from any device with an internet connection and a web browser.
Web applications are built using a combination of front-end and back-end technologies. The front-end of a web application is responsible for the user interface and the user experience. It is typically built using HTML, CSS, and JavaScript, and it runs on the client-side, meaning that it is executed in the user’s web browser.
The back-end of a web application is responsible for the server-side functionality and the processing of data. It is typically built using programming languages such as PHP, Python, Ruby, or Java, and it runs on the server-side.
Web applications can range from simple, static pages to complex, dynamic applications that incorporate databases, APIs, and other third-party services. They can be used for a wide range of purposes, including e-commerce, social networking, content management, and enterprise resource planning.
One of the key advantages of web applications is that they can be easily updated and maintained. Since they run on a web server, updates and changes can be made centrally, without the need for users to install new software or download updates.
In summary, web applications are software applications that run on a web server and are accessed through a web browser. They are built using a combination of front-end and back-end technologies and can range from simple, static pages to complex, dynamic applications.
