<<Apache 15%
Apache HTTP Server, product of the Apache Software Foundation is a free software/open source web server for Unix-like systems, Windows, Novell NetWare and other platforms. Apache is notable for playing a key role in the initial growth of the World Wide Web , and continues to be the most popular web server in use, serving as the de facto reference platform against which other web servers are designed and judged. Apache is primarily used to serve static and dynamic content on the World Wide Web. Many web applications are designed expecting the environment and features that Apache provides. Apache is the web server component of the popular LAMP web server application stack, alongside Linux, MySQL, and the PHP / Perl / Python programming languages.
<<HTTP 7%
Hypertext Transfer Protocol (HTTP) is a method used to transfer or convey information on the World Wide Web . Its original purpose was to provide a way to publish and retrieve HTML pages. HTTP is a request/response protocol between clients and servers . The originating client, such as a web browser, initiates a request by establishing a Transmission Control Protocol (TCP) connection to a particular port on a remote host (port 80 by default). The destination HTTP server listening on that port, which stores resources such as HTML files and images, waits for the client to send a request message. HTTPS (with S for secure) is the sercure variation of HTTP that use an added encryption layer of SSL or TLS to protect the traffic.
<<URL 7%
Uniform Resource Locator (URL) is a technical, Web-related term used to identify a resource over the Internet. Also called "Web address", it provides a means of locating the resource by describing its access mechanism (e.g., its network ‘location’) within a chain of ASCII letters. The idea of a uniform syntax for global identifiers of network-retrievable documents was the core idea of the World Wide Web. More information here : http://en.wikipedia.org/wiki/URL
<<WebDAV 7%
WebDAV (Web-based Distributed Authoring and Versioning) refers to the set of extensions to the HTTP protocol that allows users to collaboratively edit and manage files on remote web servers. The WebDAV protocol's aim was to make the World Wide Web a readable and writable medium. It provides functionality to create, change and move documents on a remote server (typically a web server or "web share").WebDAV also allows client/server groupware systems to store and fetch objects such as calendar items and address book entries instead of web pages. It enables to share calendar events between Mozilla Sunbird , Apple iCal , Ximian Evolution (see : iCalendar in Wikipedia).
<<Web Site 7%
A web site is a collection of web pages, images, videos and other digital assets that is hosted on a web server, usually accessible via the Internet. A web page is a document, typically written in HTML , that is almost always accessible via HTTP, a protocol that transfers information from the web server to display in the user's web browser. All publicly accessible websites are seen collectively as constituting the World Wide Web . The pages of websites can usually be accessed from a common root URL called the homepage, and usually reside on the same physical server. The URLs of the pages organize them into a hierarchy, although the hyperlinks between them control how the reader perceives the overall structure and how the traffic flows between the different parts of the sites. The web pages can be uploaded via File Transfer Protocol (FTP) to the web server that allows individuals and organizations to provide their own web sites accessible via Internet. One can set up his own web site by himself (with a little understanding of html) or call upon a web-designer to do the job.
<<World Wide Web 31%
The World Wide Web (or the "Web") is a system of interlinked, hypertext documents accessed via the Internet. With a Web browser, a user views Web pages that may contain text, images, and other multimedia and navigates between them using hyperlinks. The Web was created around 1990 by the Englishman Tim Berners-Lee and the Belgian Robert Cailliau working at CERN in Geneva, Switzerland. Since then, Berners-Lee has played an active role in guiding the development of Web standards (such as the markup languages in which Web pages are composed), and in recent years has advocated his vision of a Semantic Web. The Web is only one application of the Internet amongst others, like emailing, instant messaging, Usenet, etc.
<<XHTML 7%
The Extensible HyperText Markup Language, or XHTML, is a markup language that has the same depth of expression as HTML , but also conforms to XML syntax. Whereas HTML is an application of SGML, a very flexible markup language, XHTML is an application of XML, a more restrictive subset of SGML. Because they need to be well-formed, true XHTML documents allow for automated processing to be performed using standard XML tools—unlike HTML, which requires a relatively complex, lenient, and generally custom parser. XHTML can be thought of as the intersection of HTML and XML in many respects, since it is a reformulation of HTML in XML. XHTML 1.1 became a World Wide Web Consortium (W3C) recommendation on May 31, 2001.
