Web development is the work involved in developing a Web site for the Internet (World Wide Web) or an
intranet (a private network). Web development can range from developing a simple single static page of
plain text to complex web applications, electronic businesses, and social network services. A more
comprehensive list of tasks to which Web development commonly refers, may include Web engineering, Web
design, Web content development, client liaison, client-side/server-side scripting, Web server and network
security configuration, and e-commerce development.
Among Web professionals, "Web development" usually refers to the main non-design aspects of building Web
sites: writing markup and coding. Web development may use content management systems (CMS) to make
content changes easier and available with basic technical skills.
For larger organizations and businesses, Web development teams can consist of hundreds of people (Web
developers) and follow standard methods like Agile methodologies while developing Web sites. Smaller
organizations may only require a single permanent or contracting developer, or secondary assignment to
related job positions such as a graphic designer or information systems technician. Web development may be a
collaborative effort between departments rather than the domain of a designated department. There are three
kinds of Web developer specialization: front-end developer, back-end developer, and full-stack developer.
Front-end developers are responsible for behavior and visuals that run in the user browser, while back-end
developers deal with the servers.
