1. Asynchronous Transfer Mode. High Speed (up to 155 Mbps), high bandwidth, low-delay, transport technology, integrating multiple data types (voice, video, and data), International Telecommunications Union (ITU) has selected ATM as the basis for the future broadband network because of its flexibility and suitability for both transmission and switching. It may be used in the phone and computer networks of the future. It is also a multiplexed information transfer technique of sending data in irregular time intervals using a code such as ASCII. ATM allows most modern computers to communicate with one another easily. From Glossary of Distance Education and Internet Terminology
