The World Wide Web (WWW) is an information system that allows access to documents and other web resources over the internet.
Web resources are made available through web servers and are accessed by web browsers using URLs.
The original document type is a web page formatted in Hypertext Markup Language (HTML), which supports text, images, video and audio content, and scripts for user interaction.
Web navigation involves following hyperlinks to access other web resources, and web applications are web pages that function as application software.
The WWW was invented by Tim Berners-Lee at CERN in 1989 and opened to the public in 1991 as a "universal linked information system."
The WWW has become the world's dominant software platform and is used by billions of people worldwide.
Web pages contain hyperlinks to other related pages, creating a web of information.
The webgraph describes the hyperlink structure of the web, and link rot refers to hyperlinks that become obsolete over time.
The use of www as a prefix for web hostnames is not required by any technical or policy standard, and many websites do not use it.
The scheme specifiers http:// and https:// refer to Hypertext Transfer Protocol or HTTP Secure, respectively, and specify the communication protocol to use for the request and response.
A web page is a document suitable for the World Wide Web and web browsers that can be retrieved from a remote web server.Web Fundamentals: What You Need to Know
A static web page is delivered exactly as stored, as web content in the web server's file system, while a dynamic web page is generated by a web application, usually driven by server-side software.
Websites are collections of related web resources including web pages, multimedia content, typically identified with a common domain name, and published on at least one web server.
A web browser is a software user agent for accessing information on the World Wide Web, which is used to connect to a website's server and display its pages.
A web server is server software, or hardware dedicated to running said software, that can satisfy World Wide Web client requests.
An HTTP cookie is a small piece of data sent from a website and stored on the user's computer by the user's web browser while the user is browsing, used to remember stateful information or to record the user's browsing activity.
A web search engine is a software system that is designed to carry out web search (Internet search), which means to search the World Wide Web in a systematic way for particular information specified in a web search query.
The deep web, invisible web, or hidden web are parts of the World Wide Web whose contents are not indexed by standard web search engines.
A web cache is a server computer located either on the public Internet or within an enterprise that stores recently accessed web pages to improve response time for users when the same content is requested within a certain time after the original request.
For criminals, the Web has become a venue to spread malware and engage in a range of cybercrimes, including identity theft, fraud, espionage, and intelligence gathering.
Most web-based attacks take place on legitimate websites, and most are hosted in the United States, China, and Russia.
Common web-based vulnerabilities include SQL injection attacks, cross-site scripting (XSS), and phishing.
Proposed solutions to web security issues vary, including governance and compliance suites, real-time inspection of programming code, and digital rights management enforced in the infrastructure.Privacy, Standards, Accessibility, and Internationalization on the Web
When a client requests a web page, the server can identify the request's IP address and web servers usually log IP addresses in a log file.
Personally identifiable information, such as real name, address, e-mail address, etc., can be associated with current web traffic by web-based entities and used to build a profile of the individual.
Social networking sites try to get users to use their real names, interests, and locations, which can be problematic for users.
Web standards include many interdependent standards and specifications, some of which govern aspects of the Internet, not just the World Wide Web.
Web standards are not fixed sets of rules but are constantly evolving sets of finalized technical specifications of web technologies.
There are methods for accessing the Web in alternative mediums and formats to facilitate use by individuals with disabilities.
The Web must be accessible, so it can provide equal access and equal opportunity to people with disabilities.
The W3C Internationalisation Activity assures that web technology works in all languages, scripts, and cultures.
Unicode has surpassed both ASCII and Western European as the Web's most frequently used character encoding.
RFC 3987 allows more characters—any character in the Universal Character Set—and now a resource can be identified by IRI in any language.
The W3C Web Accessibility Initiative led to simple guidelines that web content authors as well as software developers can use to make the Web accessible to persons who may or may not be using assistive technology.
International co-operation in the W3C Web Accessibility Initiative led to simple guidelines that web content authors as well as software developers can use to make the Web accessible to persons who may or may not be using assistive technology.
