A web application is an application that is accessed via a web browser and uses browser-supported programming languages like HTML, PHP, JavaScript, and XML. It allows software to be updated without users having to update any software and can be accessed from anywhere through a web browser. The history of web applications began in 1995 with JavaScript being introduced to create dynamic elements on web pages. Technologies like Flash, Ajax, and HTML5 have continued advancing the capabilities of web applications. Web applications provide advantages like cross-platform access from any device with a browser and easy updating without software installations. However, they also rely on internet connections and server availability.

- 2. What is a Web Application Web Application simply means the application or software that usage a web browser as a client . Web Application is mainly coded in browsersupported programming language like HTML, PHP, Javascript, XML, Perl, Python. It is popular due to its fast update without updating any software or any and due to convenience of using a web browser
- 3. History In 1995 “Netscape” introduced a client side scripting language called “JavaScript” which allowed programmers to create dynamic element on the web that run on client side. In 1996 “Macromedia” introduces “Flash”, a vector animation player that could be added to the browser as a plugin to play animations over web pages. In 1999 the “web application” concept was introduced on the java language. In 2005 the term “Ajax” was coined which changed the web application sector like coin changing its side. The new interactive application were created using it like Gmail, etc. In 2011 HTML5 was introduced which creates interactive designs and functionality of animation without any plug-in. It nearly changes the concept of what an web-application can be !
- 4. Advantages No specially specified OS is required for it. Can be accessed anytime from anywhere. Doesn’t require reinstalling or update like other software. It requires little or can be said as negligible disk and memory space. They integrate easily with server-side application like email and searching. With the help of HTML5, programmers can create web based games and other without any plug-in or installation. Are compatible with tablets, mobile, pc and other devices having a web browser.
- 5. Disadvantages In practice the user experience slightly lacks as compared to the thick clients like desktop application. Browser based application rely over the internet connection, so when the internet connection is disconnected than the application becomes useless. Since many application are not opensource than they should rely on the 3rd party application not allowing any customization for better user experience. These application totally rely on the server on which they are hosted so if anything happens to the server or the company the application is useless.
- 6. How does it work ???
- 8. Summary As we can say that the web application is the future of application but it needs few improvement. Web application can be used for building cross platform software.
