Web development refers in general to the tasks associated with developing websites for hosting via intranet or internet. The web development process includes web design, web content development, client-side/server-side scripting and network security configuration, among other tasks.
In a broader sense, web development encompasses all the actions, updates, and operations required to build, maintain and manage a website to ensure its performance, user experience, and speed are optimal.
Back-end, or server-side, development builds the digital infrastructure and behind-the-scenes functionality of a website to ensure it runs smoothly. The back end is made up of the server the website is hosted on, an application that operates the site and a database that stores the site data. Developers can use a variety of programming languages for back-end development, as servers can be configured to understand virtually any language
CONTENT MANAGEMENT SYSTEM
Websites can be built by scratch but many developers choose to use web applications to create and manage on-site content called content management systems (CMS), such as WordPress or Drupal. These systems streamline web development by providing building blocks that create the structure of a website. Plug-ins and add-ons allow developers to expand the functionality they can build into websites without the need to code everything out.
