Telnet allows users to remotely access other computers that are connected to a network. Once installed, a Telnet lets the user execute commands on the other computer being accessed via the internet. It is a quick and easy way of making changes to a computer without having to actually be present in front of the system. Telnet programs are not as popular as they once were, but it is widely known that some remote functions perform faster over Telnet that with any other remote access systems.

Uses of Telnet – Old and New

At one time, telnet was the only way to access numerous government databases. It was phased out as more secure databases were introduced. Library catalogs were also accessible by using Telnet. Telnet is now used to play some online text based games.
