HTTP is an acronym for Hypertext Transfer Protocol. HTTP is the set of rules,
or protocol, that enables hypertext data to be transferred from one computer to another,
and is based on the client/server principle.
Hypertext is text that is coded using the Hypertext Markup Language. These codes and HTTP
work together to link resources to each other. HTTP enables users to retrieve a wide variety
of resources such as text, graphics, sound, animation and other hypertext documents, and allows
hypertext access to other Internet protocols.
A URL is a Uniform Resource Locator. URLs provide a standard, hierarchical way of identifying & locating Internet resources on the World Wide Web. URLs include letters, numbers, and punctuation. The first section of a URL specifies the type of resource to be accessed and the protocol to be used to transmit the resource, for example HTTP. The remainder of the URL indicates the name of the computer and its domain, the port number if different than 80, and often includes the directory path and file name for a specific resource.
HTML is an acronym for Hypertext Markup Language. HTML is a set of standardized codes, or tags, that have been derived from the SGML standard. HTML defines and describes the structure of a web page and is used to prepare documents for the World Wide Web. In addition, HTML documents are portable they can be viewed with any web browser on any type of computer. The tags used in HTML consist of a code in between two wickets. For example, <I> and </I> are the starting and ending tags used to indicate an area of text as italic. Some tags, such the paragraph break, do not require an ending tag.
