1. Introduction In this report, the OSI and TCP/IP models will be compared after going through a brief history and how the models were made. The report will bring the reader a greater understanding about the OSI and TCP model. The model shows the different layers for example for the OSI model it has the following layers: Application layer, Presentation layer, Session layer, Transport layer, Network layer, Data-Link layer and Physical layer. The similarities in the TCP model would be: the Application layer and the Transport layer. This is then compared for the differences to see which models layer has, that is different to the other. 2. The OSI Model 2.1. Brief History In the late 1970’s, two projects started separately, with the same ambitions: to characterize a unifying standard for the architecture of networking systems. An individual was administered by the International Organization for Standardization (ISO), and the other was undertaken by the International Telegraph and Telephone Consultative Committee known as CCITT. In 1983, these two documents were merged to form a criterion called The Basic Reference Model for Open Systems Interconnection. This was too long to pronounce, so the standard is usually referred to as the Open Systems Interconnection Reference Model, or more commonly known as the OSI Model. The OSI model had two major parts: an abstract model of networking, called the “Basic Reference Model” or the “seven-layer model”, and a set of precise
