Getting Started with Telnet

This blog will explain how to enable and use Telnet on both Windows and Mac.

What is Telnet? 

Telnet is a network protocol used to virtually access devices, establishing a two-way communication.

When Telnet is capitalized, we’re talking about the protocol. When telnet is lower cased, we’re talking about establishing the connection.
