HTML stands for HyperText Markup Language

HTML, Hyperlink, Hypertext, HTTP Protocol

HTML

HTML stands for HyperText Markup Language English, meaning Markup Language HyperText . This is the name of the programming language used in the elaboration of Web pages , and which serves as a reference standard for coding and structuring them, through a code of the same name (html).

The W3C or World Wide Web Consortium, an organization dedicated to the standardization of the parameters of the Network , uses html as the most important web language , and to which virtually all browsers and browsers have adapted . It is crucial, then, for the development and expansion of the Network.

This code operates based on the differentiation and location of the different elements that make up the Web page . Thus, the code is light and purely textual , but it contains the URLs of the images, audios, videos and other content that will be retrieved by the browser to assemble the page, as well as the indications for the graphic and aesthetic representation of the text that is Find in it.

The HTML has gone through several versions and modifications , moving towards a more efficient and faster operating model, which forces different browser software companies to apply consecutive patches to their products to update them with each new version.

Hyperlink

Hyperlink or hyperlink is called a type of element present in electronic documents ( Web pages , emails, digital text documents , etc.) that refers to another document, a specific part of the same document or another resource of any nature, such as online searches , purchase mechanisms, subscriptions, etc.

The hyperlinks, then, consist in the possibility of “jumping” from one text to another , from one information to another, following the thread of association of the user’s interests, rather than a linear and successive logic as occurs in traditional culture.

These types of associations are fundamental in the operation of the World Wide Web , since a hyperlink, together with an access protocol to an established data network, allows you to “visit” the different resources available online , either to view or download them to the computer .

Every hyperlink has two ends: a source anchor and a destination link. The former are usually highlighted in Internet browsers or browsers (in color and underlined as well ). By selecting the point of origin you have access to a single destination, which can be of a different multimedia nature . When hyperlinks stop operating, because they fail to track the promised content, they are told they are “broken.”

 HTTP Protocol

The http (of English HyperText Transfer Protocol or Protocol of Transfer of Hyper Texts) is the protocol of transmission of information of the World Wide Web , that is to say, the code that is established so that the requesting computer and the one that contains the requested information can “Speak” the same language when transmitting information over the network .

The http establishes criteria for computer syntax and semantics (form and meaning) for the establishment of communication between the different elements that constitute the web architecture: servers , clients, proxies. It was created in 1999 by the World Wide Web Consortium in collaboration with the Internet Engineering Task Force.

It is a “stateless” protocol, that is, it does not keep a record of previous visits but always begins again. The information related to previous visits is stored in these systems in the so-called “cookies”, stored in the client system.

The http has gone through numerous versions until reaching the current one at the beginning of the 21st century, called HTTP / 2 . Their first attempts occurred in 1991 and they threw partial versions in 1996, 1999, 2000 and, finally, the one in force in 2015.

Hypertext

The hypertext information is an authoring tool, link and distributing information from various sources, which operates based on a structure , not sequential but associative, ie nonlinear, direct, but leads from one thing to another, very The way of human thought .

This occurs through associative links called hyperlinks or cross-references , which lead from a main document to secondary ones in which it is possible to rescue supplementary or complementary information. This dynamic is called a link or link (in English), and is essential in the use of the Internet .

Hypertext, despite its name, is not limited to written or textual information, but can link to images, sounds , audiovisual documents, entire Web pages or any other form of digital action (send an e-mail, download a file , etc.). The coexistence of this type of formats is usually called hypermedia .

Hypertext documents must be opened and read with a browser or browser (also “viewer” or “client”), which is a computer software designed for it, and the action of jumping from one hypertext to others available on the Web is called surf the Internet .
