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.
When Earl S. Tupper invented Poly-T, a new and better form of plastic, he opened the door for plastic to become a key material in household products. His Tupperware line, with its newly invented stay-fresh lid, also proved that goods made out of plastic could be useful, and attractive and lightweight.In addition, Tupper's company had a big impact on how household products and other items, especially for women, were sold.arl Tupper sold Tupperware to the Rexall Corporation in 1958. Rexall changed its name to Dart Industries, which merged with Kraft Industries to become Dart and Kraft a decade later. In 1986, Dart and Kraft split and Tupperware became part of one of the new companies, Premark International.
