What is a web application?
A web application (web app) is an application program that is stored on a remote server and delivered over the internet through a browser interface. Web services are web apps by definition and many, although not all, websites contain web apps.
Developers design web applications for a wide variety of uses and users, from an organization to an individual for numerous reasons. Commonly used web applications can include webmail, online calculators or e-commerce shops. While users can only access some web apps by a specific browser, most are available no matter the browser.
How web applications work ?
Web applications do not need to be downloaded since they are accessed through a network. Users can access a web application through a web browser, such as Google Chrome, Mozilla Firefox or Safari.
For a web app to operate, it needs a web server, application server and database. Web servers manage the requests that come from a client, while the application server completes the requested task. A database stores any necessary information.
Web applications typically have short development cycles and small development teams. Developers write most web apps in JavaScript, HTML5 or CSS. Client-side programming typically utilizes these languages, which help build an application’s front-end. Server-side programming creates the scripts a web app will use. Languages such as Python, Java and Ruby are commonly used in server-side programming.
