HyperText Transfer Protocol

The choice of a data transfer protocol (middle layer) is also important to the operation of a federated information system. An ideal data transfer protocol would be architecture-independent, provide reliable data transfer over existing network protocols and, ideally, it would already be globally disseminated. Today (in 2003), the choice seems obvious HTTP (HyperText Transfer Protocol).

HTTP A TCP/IP protocol which defines how World Wide Web content is downloaded and displayed in your browser. HTTP stands for Hypertext Transfer Protocol. 

Hypertext Transfer Protocol (HTTP) HTTP is the protocol of the World Wide Web, and is used to send and receive Web pages and other content from an HTTP server (Web server). HTTP makes use of linked pages, accessed via hyperlinks, which are words or pictures that, when clicked on, take you to another page. 

World Wide Web (WWW) This is the graphical extension of the Internet that features millions of pages of information accessed though the use of the Hypertext Transfer Protocol (HTTP). 

World Wide Web. The World Wide Web (WWW) is the world wide connection of computer servers and a way of using the vast interconnected network to find and view information from around the world (Bullock, 2003 Stout, 1996). Internet uses a language, TCP/IP for talking back and forth. The TCP part determines how to take apart a message into small packets that travel on the Internet and then reassemble them at the other end. The IP part determines how to get to other places on the Internet. The WWW uses an additional language called the HyperText Transfer Protocol (HTTP). The main use of the Web is for information retrieval, whereby multimedia documents are copied for... 

Hypertext Transfer Protocol (HTTP) is the application-level network protocol for transferring Web content between servers and clients. (Hypertext is a special database system of multimedia objects linked to each other.) HTTP uses the services of the TCP transport protocol. It transfers independently the objects (text, graphics, images, etc.), that build up a page. Together with each object, a special header is also passed. The header contains information alx>ut the type of the object, its size, its last modification time, and so on. HTTP also supports the use of proxy and cache servers. HTTP proxies are implemented in firewalls to pass HTTP traffic between the protected network and the Internet Object caches are used to save bandwidth on overloaded lines and to speed up the retrieval process.

In order to make the Web work in the way described above, Berners-Lee needed to develop three key elements that would build on top of the features already provided by the Internet. In his book Weaving the Web, he ranks these in the following order Universal Resource Identifiers (URIs), HyperText Transfer Protocol (HTTP), and HyperText Mark-up Language (HTML). 

URIs consist of two parts, a scheme and a path. A colon separates the scheme and the path in the written URI. In the URI http //www.scit.wlv.ac.uk, the scheme is http (hypertext transfer protocol) and the path is //www.scit.wlv.ac.uk. The way in which the path is interpreted depends on the scheme in use. The most commonly used URI schemes are listed in Table I. All the schemes shown in Table I are normally referred to as URLs the prefix urn is reserved for future use when a Internet resource naming mechanism comes into operation. 

Tha basic architecture of the Web consists of browsers that act as clients requesting information from Web servers. Computer-to-computer communications are described in terms of protocols, and Web interactions are no exception to this rule. In order to implement the prototype Web, Berners-Lee had to define the interactions that were permissible between server and client (normally a browser, but it could in fact be any program). The HyperText Transfer Protocol (HTTP) describes these interactions. The basis of the design of HTTP was that it should make the time taken to retrieve a document from a server as short as possible. The essential interchange is Give me this document and Here it is. ...

Of course, this unit requires a comprehensive, stateless, and well-documented API. A DPU should be represented as a library or framework that includes at least hypertext transfer protocol (HTTP) or hypertext transfer protocol secure (HTTPS) service for data exchange. 

Hypertext Transfer Protocol (HTTP) Set of standard rules that allow HTML data to be transferred between computers. 

New hardware devices and software have continuously been developed to make sharing information via the Internet easier and faster. A language called hypertext markup langui e (HTML) was created to design and format the user interface to Web page content for transmission over the Internet, based on hypertext transfer protocol (HTTP). As of 2011, there are many Web applications available to computer and cell phone users all over the world.
