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.
The Whopper was the first big item added to their menu in 1957 and was hugely successful and still is; it has become what Burger King is famous for and is considered their signature hamburger. In 1959, the company wasnât doing very well and was bought out by two franchisees.
