1.vtn is the abbreviation of Network Virtual Terminal (VTN) and VirtualTerminalNetwork. The data transmitted on the network virtual terminal VTN adopts 8-8 byte data.

2. Virtual Terminal (VT) is an International Organization for Standardization (ISO) protocol, which provides remote terminal simulation similar to Internet Telnet protocol.

3. Users of remote terminals can run applications on remote computers as if they were sitting in front of this computer.

4. Through the software of the virtual terminal, the virtual terminal can also expand the functions of the standard terminal of the large computer. Through the virtual terminal, not only the data from the personal computer can be transmitted to the large computer, but also the data from the large computer can be transmitted to the personal computer for further processing.

Virtual terminals are also used in modern large computers, so that old programs that need terminals can be disguised as terminals, but in fact, it turns the display of programs into graphics cards.

6.Linux and most other Unix-like operating systems based on personal computers pretend to have six or ten such "virtual" terminals.
