Network Protocol X File Transfer Protocol

Network Protocol-FTP protocol

(File Transfer Protocol). This is one of the most familiar network protocols and the most widely used File Transfer Protocol on the Internet. It is mainly used to upload and download files between two computers. One computer serves as the FTP client and the other as the FTP server. You can use the FTP protocol to upload and download almost all file types, such as TXT, EXE, DOC, MP3, ZIP, and RAR.

Application: in practical applications, FTP can be used not only as the main format for downloading network files, but also as a separate command. For example, when we are in the next MP3, often encounter ftp://www.xxx.com/1.mp3, of which, ftp: // indicates the file transmission format, www.xxx.com others remote computer domain name, 1.mp3 is to download the file.

In addition, ftp commands are integrated in Windows. For example, if you type "ftpwww.xxx.com" in the "command prompt" of Windows XP, you can enable the remote computer www.xxx.com, for specific command parameters, enter "ftp /? ".

Network Protocol-Telnet protocol

Note: The remote logon protocol is also a simulated network protocol widely used on the Internet. Telnet is also a common program for remote logon. Using the Telnet protocol, you can use your computer as a terminal for a remote computer and use the Telnet program to log on to the remote Telnet computer. Generally, you can use an authorized user name and password to log on. After logging on, you can use the hard disk of the remote computer and run applications like using a local computer.

Application: in Windows, we can remotely log on using the Telnet command. For example, if you type "telnet www.xxx.com", you can connect to the remote computer www.xxx.com, in addition, you can specify the logon user name, terminal type, and port number by setting parameters. For specific command parameters, you can enter "telnet /?" View ).

Network Protocol-NEWS Protocol

Note: The network newsgroup protocol allows you to access various newsgroups on the Internet and obtain the required information and resources from newsgroups, including politics, economy, culture, humanities, geography, and technology. You can also publish some information in news groups.

Application: the Protocol is in the format of news: newsgroup. newsgroup indicates the address of the network newsgroup. For example, if the IP address of the Microsoft Chinese newsgroup server is msnews.microsoft.com, enter: news: msnews.microsoft.com in the address bar of the IE browser, press enter to open OE to access the newsgroup.

Network Protocol-Mailto Protocol

Note: The email protocol allows you to create a hyperlink pointing to an email address, through which you can send emails over the Internet.

Application: for example, in the Web code insert A href = "mailto: abc@xxx.com", then click the hyperlink will open OE and other mail client program, enter the corresponding content can

 
 

  
  
[url=mailto:abc@xxx.com]  
  
  
 
  
  
abc@xxx.com  
  
  
 
  
  
[/url] 
 
 

Send an email. In addition, enter mailto: abc@xxx.com in the address bar of IE browser, after the press ENTER can also achieve this effect.

Network Protocol-File Protocol

Note: This indicates the local File transfer protocol. The File protocol is mainly used to access files on the Local Computer, just like opening files in Windows Resource Manager.

Application: to use the File protocol, the basic format is as follows: file: // File path. For example, to open the 1.swf file in the F: Flash folder, you can enter: file: // f:/flash/1.swf and press Enter.
