3270 - A family of IBM terminals, printers and other peripheral devices that attach to mainframe systems. The earliest terminals were the IBM 3277 and 3278--hence the "3270" family designation. Telnet 3270, or TN3270 describes either the process of sending and receiving 3270 data streams using the Telnet protocol or the software that emulates a 3270 class terminal that communicates using that process. TN3270 allows a 3270 terminal emulator to communicate over a TCP/IP network. Standard telnet clients cannot be used as a substitute for TN3270 clients, as they use fundamentally different techniques for exchanging data.

Simplified: A 3270 Emulator is a computer program that duplicates the functions of an IBM 3270 mainframe computer terminal on a Windows or Macintosh computer.
