TCP/IP Model
, ► TCP/IP was designed and developed by the Department of Defense
(DoD) in the 1960s and is based on standard protocols. It stands for
Transmission Control Protocol/Internet Protocol. The TCP/IP model is a
concise version of the OSI model. It contains four layers, unlike the seven
layers in the OSI (Open System Interconnection) model.
► The number of layers is sometimes referred to as five or four. The
Physical Layer and Data Link Layer are referred to as one single layer as
the ‘Physical Layer’ or ‘Network Interface Layer’ in the 4-layer reference.
