Telnet
Telnet is a program that allows you to log into other internet computers.
With telnet you can log onto databases, library catalogs, and thousands of information servers.
“Guest telnet” allows you to log into a computer through a special restricted guest account. This is how many internet databases are accessed.
“Full telnet” allows you to log into a computer on which you have a regular account. You can do your normal work on this computer, from any other internet-connected computer.
