Web pages can be viewed or otherwise accessed from a range of computer-based and Internet-enabled devices of various sizes, including desktop computers, laptops, tablet computers and smartphones.
A website is hosted on a computer system known as a web server, also called an HTTP (Hyper Text Transfer Protocol) server.
A dynamic website is one that changes or customizes itself frequently and automatically.
It is primarily coded in Hypertext Markup Language (HTML); Cascading Style Sheets (CSS) are used to control appearance beyond basic HTML.
Images are commonly used to effect the desired appearance and as part of the main content.
They may incorporate elements from other websites with suitable markup anchors.
Web pages are accessed and transported with the Hypertext Transfer Protocol (HTTP), which may optionally employ encryption (HTTP Secure, HTTPS) to provide security and privacy for the user.
Some websites require user registration or subscription to access content.
Examples of subscription websites include many business sites, news websites, academic journal websites, gaming websites, file-sharing websites, message boards, web-based email, social networking websites, websites providing real-time stock market data, as well as sites providing various other services.There are a wide range of software systems, such as CGI, Java Servlets and Java Server Pages (JSP), Active Server Pages and Cold Fusion (CFML) that are available to generate dynamic web systems and dynamic sites.Various web application frameworks and web template systems are available for general-use programming languages like Perl, PHP, Python and Ruby to make it faster and easier to create complex dynamic websites.Any website can contain a hyperlink to any other website, so the distinction between individual sites, as perceived by the user, can be blurred.Websites are written in, or converted to, HTML (Hyper Text Markup Language) and are accessed using a software interface classified as a user agent.The user's application, often a web browser, renders the page content according to its HTML markup instructions onto a display terminal.
