A single web server may provide multiple websites, while some websites, especially the most popular ones, may be provided by multiple servers. This markup language supports plain text, images, embedded video and audio contents, and scripts (short programs) that implement complex user interaction. Servers and resources on the World Wide Web are identified and located through a character string called a uniform resource locator (URL). Blair's publicist told the BBC www.re-mine.eu that she "experienced a medical emergency that led to the alleged conduct". Both Republican and Democratic lawmakers have criticised the deal, which was announced weeks before the US midterm elections.

• Unlike Hypercard, Berners-Lee's new system from the outset was meant to support links between multiple databases on independent computers, and to allow simultaneous access by many users from any computer on the Internet.
• After the NCSA released the Mosaic web browser later that year, the Web's popularity grew rapidly as thousands of websites sprang up in less than a year.
• Hyperlinking between web pages conveys to the reader the site structure and guides the navigation of the site, which often starts with a home page containing a directory of the site web content.
• HTML provides a means to create structured documents by denoting structural semantics for text such as headings, paragraphs, lists, links, quotes, and other items.

Static page

With modern and potential facial recognition technology, it may then be possible to relate that face with other, previously anonymous, images, events, and scenarios that have been imaged elsewhere. Photographs and videos posted onto websites have caused particular problems, as they can add a person's face to an online profile. Modern social networking websites allow fine-grained control of the privacy settings for each posting, but these can be complex and not easy to find or use, especially for beginners.

A client-side dynamic web page processes the web page using JavaScript running in the browser. A static web page (sometimes called a flat page/stationary page) is a web page that is delivered to the user exactly as stored, in contrast to dynamic web pages which are generated by a web application. Dynamic web pages are used when each user may require completely different information, for example, bank websites, web email, etc. The web browser uses the Hypertext Transfer Protocol (HTTP) to make such requests to the web server. The use of a subdomain name is useful for load balancing incoming web traffic by creating a CNAME record that points to a cluster of web servers. Many established websites still use the prefix, or they employ other subdomain names such as www2, secure or en for special purposes.

Unless the server-browser communication uses HTTPS encryption, web requests and responses travel in plain text across the Internet and can be viewed, recorded, and cached by intermediate systems. Jonathan Zittrain has said users sharing responsibility for computing safety is far preferable to locking down the Internet. The most common of all malware threats is SQL injection attacks against websites.

Limited public access to the Internet led to pressure from consumers and corporations to privatise the network. The latter is typically much faster and more easily cached but cannot deliver dynamic content. Usually, this function is used to generate HTML documents dynamically ("on-the-fly") as opposed to returning static documents. While the primary function is to serve content, full implementation of HTTP also includes ways of receiving content from clients. Pages delivered are most frequently HTML documents, which may include images, style sheets and scripts in addition to the text content. A web server processes incoming network requests over HTTP and several other related protocols.

To connect to a website's server and display its pages, a user needs to have a web browser program. Hyperlinking between web pages conveys to the reader the site structure and guides the navigation of the site, which often starts with a home page containing a directory of the site web content. They may incorporate elements from other websites with suitable markup anchors. Client-side scripting, server-side scripting, or a combination of these make for the dynamic web experience in a browser.citation needed Dynamic HTML, or DHTML, is the umbrella term for technologies and methods used to create web pages that are not static web pages, though it has fallen out of common use since the popularisation of AJAX, a term which is now itself rarely used.

The W3C Internationalisation Activity assures that web technology works in all languages, scripts, and cultures. The World Wide Web Consortium claims that it is essential that the Web be accessible, so it can provide equal access and equal opportunity to people with disabilities. There are methods for accessing the Web in alternative mediums and formats to facilitate use by individuals with disabilities. Even when not web-focused, such standards directly or indirectly affect the development and administration of websites and web services.

This four-channel WDM technology allowed more information to be sent simultaneously over a single optical fibre, effectively boosting network capacity. This spurred developers to seek solutions to reduce the time and cost of laying new fibre and increase the amount of information that can be sent on a single fibre, to meet the growing needs of the public. The privatisation of the Internet and the release of the World Wide Web to the public in 1993 led to an increased demand for Internet capabilities. However, access to the ARPANET was limited to researchers, and in 1985, the National Science Foundation founded the National Science Foundation Network (NSFNET), a program that provided supercomputer access to researchers. The technology uses optical microsystems like tunable lasers, filters, attenuators, switches, and wavelength-selective switches to manage and operate these networks.
