Definition - Virtual Terminal Software
In the past, to access the server, we need a terminal physical network. Now, the role of the physical terminal, it can be replaced with a software virtual terminal (VT). This application will emulate physical terminal functions so that it can access the server.
What is network software VT function?
In computer networking, software VT can also be used with a terminal emulator. An IT, within a company usually using software VT in the networks so PC employees can connect to the server of the company.
This situation is very likely to be carried out because the virtual terminal can connect a PC to the server until the distant range (need an internet connection). For security, each communication that occurs via the virtual terminal requires that the user type the username and password, or a secret order on the command line Interface (CLI) VT for security.
Protocol communications Virtual Terminal
And for communication lines, it usually uses network protocols which are quite familiar, like SSH, FTP, Telnet, etc. So that the communication process can run even though the client PC and the server are different operating systems.
With the VT software, the role of the physical terminal on a network can be replaced, so that the communication process becomes more efficient.
Some software VT that is often used such as PuTTY, SuperPuTTY, PuTTY Tray, etc.
