Remote connections can be established with system over a network through SSH (secure shell) easily, we can login, perform actions or send commands to another system remotely trough this conection on the commandline. But what we cannot do is launch a GUI application for viewing content present in the remote node. This is the disadvantage of using ssh in a terminal. But this disadvantage can be easily solved by making use of "putty", a remote login application which can not only be used to login to a remote node, but also launch GUI applications. Examples of GUI applications are Browser, text viewers, etc.
