Remote login occurs when a user connects to an Internet host to use its
native user interface. In the 1970s and early 1980s, text-oriented
terminals were the predominate tools for computer users.
Protocols such as TELNET and RLOGIN were developed
for terminal users to use their terminals as if they were
directly connected to a remote system.
UN*X systems, with their predominately terminal-oriented
interface, still make heavy use of these protocols.
In the late 1980s, as graphical, window-oriented user interfaces became
popular, protocols were developed to allow remote windowing operations,
much as earlier protocols allowed remote terminal operations.
Although conceptually similar, the operation of such windowing protocols
is markedly different, and they are not discussed here. See
Systems for more information.
