A Transport Services Access Point (TSAP) is an end-point for communication between the Transport layer (layer 4) and the Session layer in the OSI (Open Systems Interconnection) reference model. Each TSAP is an address that uniquely identifies a specific instantiation of a service. TSAPs are created by concatenating the node's Network Service Access Point (NSAP) with a transport identifier, and sometimes a packet and/or protocol type.

It is believed that the first Whoopie Pie was made in the 1920s. The state of Maine likes to claim the fame of inventing it.

Some believe it was the Amish who traveled to Maine and actually introduced this cake-like dessert.
