This article mainly introduces the relevant knowledge of "what is the concept of HTTP and HTML". The editor shows you the operation process through an actual case, and the operation method is simple, fast and practical. I hope this article "what is the concept of HTTP and HTML" can help you solve the problem.

HTTP refers to a hypertext transfer protocol, which is the most widely used network protocol on the Internet; it specifies what kind of message the client may send to the server and what kind of response it may get. HTML, the full name of Hypertext markup language, is a markup language designed for "web page creation and other information that can be seen in web browsers".

What does HTTP mean?

HTTP is a hypertext transfer protocol, which is the most widely used network protocol on the Internet.

Hypertext transfer Protocol (Hypertext Transfer Protocol,HTTP) is a simple request-response protocol that usually runs on top of TCP. It specifies what kind of message the client might send to the server and what kind of response it gets. The headers of the request and response messages are given in ASCII form; the message content has a MIME-like format. This simple model was instrumental in the success of early Web because it made development and deployment very straightforward.

HTTP is an application layer protocol, which, like other application layer protocols, is designed to implement a certain kind of specific application protocol, and its function is realized by an application program running in the user space. HTTP is a protocol specification, which is recorded in the document and is the implementation of HTTP that really communicates through HTTP.

HTTP communicates based on HTTP S architecture, while the server-side implementation programs of HTTP include httpd, nginx, etc., and the client-side implementation programs are mainly Web browsers, such as Firefox, InternetExplorer, Google chrome, Safari, Opera, etc., in addition, the client command-line tools include elink, curl and so on. Web services are based on TCP, so in order to be able to respond to client requests at any time, the Web server needs to listen on the 80/TCP port. This allows communication between the client browser and the Web server through HTTP.

What does HTML mean?

The full name of HTML is Hypertext markup language, which is a markup language. It includes a series of tags. Through these tags, the document format on the network can be unified, so that the scattered Internet resources are connected into a logical whole. HTML text is a descriptive text composed of HTML commands. HTML commands can describe text, graphics, animation, sound, tables, links, and so on.

Hypertext is a way to organize information, which associates the text and charts with other information media through the method of hyperlink. These interrelated information media may be in the same text, other files, or files on a computer that is geographically distant. This way of organizing information connects the information resources distributed in different locations in a random way, which provides convenience for people to find and retrieve information.

Characteristics

Hypertext markup language document production is not very complex, but it is powerful and supports file embedding in different data formats, which is one of the reasons for the popularity of the World wide Web (WWW). Its main features are as follows:

Simplicity: hypertext markup language version upgrade adopts superset mode, which makes it more flexible and convenient.

Extensibility: the wide application of hypertext markup language brings enhanced functions and additional identifiers. Hypertext markup language adopts the way of subclass elements to ensure the expansion of the system.

Platform independence: although personal computers are popular, there are plenty of people who use other machines such as MAC, and hypertext markup language can be used on a wide range of platforms, which is another reason for the popularity of the WWW.

Versatility: in addition, HTML is the universal language of the network, a simple and universal full-set markup language. It allows web producers to create complex pages that combine text and pictures that can be viewed by anyone else on the Internet, no matter what type of computer or browser they are using.
