Quick Summary

Asynchronous Transfer Mode (ATM) is a digital network communications system designed for high-speed broadband transmissions. It functions by converting information into computer language (binary), breaking it into small pieces, addressing each piece, and sending them over a shared transmission line. This technology was first used in 1984.1

It is important to note that ATM also commonly refers to Automated Teller Machines, which are used for financial transactions like withdrawing cash, depositing checks, and transferring funds. These machines can incur fees if used outside of a customer's banking network.2
