ATM, or Asynchronous Transfer Mode, is a network technology that transmits data in fixed-size cells. It supports real-time voice, video, and data communication across high-speed networks.
For example, surveillance systems once used ATM to stream video efficiently over large infrastructures. Its ability to handle multiple types of traffic made it valuable in early broadband and telecom networks.
Although newer protocols like IP have replaced ATM in most cases, understanding it remains useful when working with legacy systems. Its fixed-cell structure set the foundation for modern data transmission.
By learning how ATM worked, professionals gain insight into the evolution of network communication.
