Difference between http and www, what is the difference between http www com?

HTTP: Hypertext Transfer Protocol

HTTP (HyperText Transfer Protocol) is the abbreviation of Hypertext Transfer Protocol, which is used to transmit data in the www mode. The client sends a request to the server with the request header containing the requested method, URI, protocol version, and a MIME-like message structure containing the request modifier, customer information, and content. The server responds with a status line that includes the version of the message protocol, the success or error code, and contains the server information, entity meta information, and possibly entity content.

www is the abbreviation of world wide web (global information network), can also be abbreviated as web, Chinese name is "world wide web". It originated in March 1989 by the European Laboratory for Particle Physics (CERN) to develop a master-slave structure distributed super-system. Through the World Wide Web, people can quickly and easily access a wealth of information by using simple methods.

Because users no longer need to care about some technical details in the process of accessing information resources through Web browsers, and the interface is very friendly, the Web has been warmly welcomed as soon as it was launched on the Internet, became popular all over the world, and has rapidly developed in the best of the world.

1、http://

Stands for Hypertext Transfer Protocol, which informs the server to display a web page, usually without input.

2、www：

It stands for the World Wide Web, which is a synthesis of information discovery technology and hypertext technology based on client-server methods. The WWW server organizes information into hypertext using Hypertext Markup Language (HTML) and uses links to jump from one site to another.

3、baidu：

The name of the company's nickname.

4、com：

The generic domain name format, short for commercial, indicates the original intent of the commercial organization to register the domain name.

There is no difference. Relationship between http and www:

1. For HTTP: It can be simply understood as which way to access the content on the server. In addition to HTTP, there are also FTP, HTTPS (HTTP plus SSL, which can be understood as HTTP plus a security lock) and other protocols.

2. www plus domain name generally refers to the main site of **; For example, the login of the mailbox**, the top-level domain name, these are the second-level domain names, and so on. But no matter how many levels of domain names there are, there will always be http: or https:

In general, www is basic, and http is based on www, so there is no essential difference between adding http or not.

HTTP is the abbreviation of Hypertext Transfer Protocol, which is one of the most widely used network protocols on the Internet. All www files must comply with this standard. HTTP was originally designed to provide a way to publish and receive HTML pages.

HTTP protocol function: a transfer protocol used to transfer hypertext from the www server segment to the local browser. It can make the browser more efficient and make the network transmission less.

It not only ensures that the computer transmits the hypertext document correctly and quickly, but also determines which part of the document is being transferred and which part of the content is displayed first (e.g., text before graphics), etc.

www is the abbreviation of world wide web, which can also be abbreviated as web, and the Chinese name is "World Wide Web".

HTTP provides access to hypertext information and is an application-layer communication protocol between the WWW browser and the WWW server. www uses the HTTP protocol to transmit various hypertext pages and data.

www adopts the working mode of the customer bulk machine server, and the workflow is as follows:

The user uses a browser or other program to establish a client connection with the server and send a browsing request;

After receiving the request, the web server returns the information to the client;

The communication is complete and the connection is closed.

Differences

HTTP is the most widely used network protocol on the Internet. www stands for the World Wide Web (also known as "web", "www", "w3.").'"World Wide Web" in English) is a system of many interlinked hypertexts, accessed via the Internet. These resources are delivered to users via the Hypertext Transfer Protocol, which in turn obtains them by clicking on a link.

All www files must comply with this standard.

1. www is the name of the host in the Zhenchun domain name system, for example, www is used with baidu dot com (domain name) for DNS resolution.

2. HTTP is an access protocol, which is used to obtain information from the server, provided that the server supports the HTTP protocol.

When input in the browser, the browser will automatically convert it to HTTP:, and then through the DNS hierarchy, get the host name www, the host IP address of the domain name, make HTTP requests, and get the information in the server.

http explained:

For HTTP: This one is really just a protocol, HTTP or Hypertext Transfer Protocol is something that we use when accessing the internet. Although we pay little attention to it, if anything, it plays a very important role.

HTTP defines the methods and rules for transferring data from our favorite servers to our computers and vice versa. For most of us non-technical people, it's no longer a concern for us, just getting what the user asks for from the server. <>
