== '''ATM Adaptation Layer 5''' ==

Computers use ''ATM Adaptation Layer 5'' (AAL5) to send data across an ATM network. Interestingly, although ATM uses small fixed-size cells, at the lowest level, AAL5 presents an interface that accepts and delivers large, variable-length packets. Thus, the interface computers use to send data makes ATM appear much like a connectionless technology. In particular, AAL5 allows each packet to contain between 1 and 65,535 octets of data.
