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.
In 1939, the Overland Candy Company introduced the predecessor to Whoppers, a malted milk candy called Giants. Overland merged with Chicago Biscuit Company, Leaf Gum, and Leaf Machinery, in 1947. Two years later, Leaf Brands reintroduced malted milk balls under the name of Whoppers.
He installed chocolate machinery in his factory in Lancaster, and produced his first chocolate bars in 1900. Other Americans began mixing in other ingredients to make up new candy bars throughout the end of the 1890's and the early 1900's. But it was World War I that really brought attention to the candy bar.
