Since we have some visitors who are not familiar with IT terminology, I would like to
try to explain ATM here. ATM is short for Asynchronous Transfer Mode. It is called also Cell Switching. It is a high-speed transfer system designed to carry voice, video, and data traffic. ATM switches can simultaneously support multiple transmissions, eliminating bottlenecks.

Interestingly enough, ATM is also acronym for
Automatic Teller Machine (Qu Kuan Ji in Chinese, a machine from which you can draw money if you insert a right bank card).
So ATM means different things for IT people
and for financial professionals.

Hope this helps. --Jabber
