History of terminals
Originally, the first terminal servers were devices providing a connection
between a so-called "green screen"
dumb terminal and a
host computer via an
Ethernet.
Latterly the term terminal server can mean either a network access server or a server operating system that provides a graphical user interface (GUI) of Windows desktop to user terminals that don't have this capability themselves. Alternatively, the desktop is provided to a remote computer in order to enable teleworking. Other examples of remote desktop delivery for the purpose of remote access to the computer that is not physically accessible.
