      HyperText Markup Language, commonly referred to as HTML, is the standard markup
      language used to create web pages. Along with CSS, and JavaScript, HTML is a cornerstone
      technology, used by most websites to create visually engaging web pages, user interfaces
      for web applications, and user interfaces for many mobile applications.[1] Web browsers
      can read HTML files and render them into visible or audible web pages. HTML describes
      the structure of a website semantically along with cues for presentation, making it a
      markup language, rather than a programming language.

      Java is a set of computer software and specifications developed by Sun Microsystems,
      later acquired by Oracle Corporation, that provides a system for developing application
      software and deploying it in a cross-mobile phones to platform computing environment. Java
      is used in a wide variety of computing platforms from embedded devices and enterprise servers
      and supercomputers. While less common, Java applets run in secure, sandboxed environments to
      provide many features of native applications and can be embedded in HTML pages.

        ASP.NET is an open-source server-side web application framework designed for web
        development to produce dynamic web pages. It was developed by Microsoft to allow programmers
        to build dynamic web sites, web applications and web services. It was first released in January
        2002 with version 1.0 of the .NET Framework, and is the successor to Microsoft\'\s Active Server
        Pages (ASP) technology. ASP.NET is built on the Common Language Runtime (CLR), allowing
        programmers to write ASP.NET code using any supported .NET language. The ASP.NET SOAP extension

        the model–view–controller (MVC) pattern. It is open-source software, apart from the ASP.NET Web
        Forms component which is proprietary. In the later versions of ASP.NET, ASP.NET MVC, ASP.NET web

        implemented as part of web browsers so that client-side scripts could interact with the

        was displayed.[5] More recently, however, it has become common in both game development
        and the creation of desktop applications.
