The Asynchronous Transfer Mode or ATM is a connection technology that works by transmitting data into organized 53 bytes (small) packages through a physical environment with a high efficiency. Packing data into small cells reduces transportation delay so the speeds reached by this technology are very high; it can reach even 10 Gb per second.
