Anonymous users2024-02-07HTTP is a protocol designed to send content from web servers located anywhere in the world to an unspecified number of users. In other words, HTTP can be thought of as a protocol designed to "distribute" files to an unspecified number of users.
HTTP is used to read web page content from a server. Web browser**HTML files and image files from a web server, etc., which are temporarily stored on the hard disk and memory of a personal computer for display.
The difference when using content such as http** software is whether it is saved as it is displayed in a web browser or not. The structure is exactly the same. So, anyone can do it as long as the file is specified.
FTP, on the other hand, is a protocol developed to "transfer" files between specific hosts. Therefore, at the beginning of FTP communication, it is necessary to run an authentication procedure that confirms the communicating party with a user ID and password.
However, when you visit the **site and perform FTP**, there is usually no window to enter the user ID and password. This is because the structure of Anonymous FTP is used.
Anonymous FTP is a method of registering an FTP server with a username as "Anonymous" and a password as the user's e-mail address. The web browser first enters anonymous in the username and the email address set in the password to access the FTP server.
In the FTP server of the **site, if the username is Anonymous, then anyone can access it, and users can access it without entering the username and password one by one.

Anonymous users2024-02-06There 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 being trapped in www, so there is no essential difference between adding http or not.
Difference between HTTP and HTTPS:
The data transmitted by the HTTP protocol is unencrypted, that is, in plaintext, so it is very insecure to use the HTTP protocol to transmit private information. In order to ensure that these private data can be encrypted and transmitted, Netscape designed the SSL (Secure Sockets Layer) protocol to encrypt the data transmitted by the HTTP protocol, thus giving birth to HTTPS. >>>More
