A web page (also written as webpage) is a document that is suitable to act as a web resource on the World Wide Web. In order to graphically display a web page, a web browser is needed. This is a type of software that can retrieve web pages from the Internet. When accessed by a web browser it may be displayed as a web page on a monitor or mobile device. Typical web pages are hypertext documents which contain hyperlinks, often referred to as links, for browsing to other web pages. The term web page usually refers to what is visible, but may also refer to the contents of the source code itself, which is usually a text file containing hypertext written in HTML or a comparable markup language. Most current web browsers include the ability to view the source code. Web browsers will frequently have to access multiple web resource elements, such as style sheets, scripts, and images, while presenting each web page. A website will typically contain a group of web pages that are linked together, or have some other coherent method of navigation. The most important web page on a website is the index page. Depending on the web server settings, the index page can have any name, but the most common names are index.html and index.php. When a browser visits the homepage of a website or any URL pointing to a directory rather than a specific file, the web server serves the index page. If no index page is defined in the configuration or no such file exists on the server, either an error or directory listing will be served to the browser. Websites and the web pages that comprise them are usually found with assistance from a search engine, but they can receive traffic from social media and other sources. On a network, a web browser can retrieve a web page from a remote web server. The web browser uses the Hypertext Transfer Protocol (HTTP) to make such requests to the web server. The web server may restrict access to a private network (for example, a corporate intranet). A static web page is delivered exactly as stored, as web content in the web server's file system. In contrast, a dynamic web page is generated by a web application, driven by server-side software, running on the client-side (on the web browser), or both. Dynamic web pages help the browser (the client) to enhance the web page through user input to the server.
