To address the problem of networks being incompatible and unable to communicate with one another, the International Organization for Standardization (ISO) researched different network schemes. It became more difficult for networks using different specifications and implementations to communicate with one another. By the mid-1980s, companies began to experience difficulties from all of the expansions they had made. The early 1980s saw tremendous increases in the number and sizes of networks. Physical layer вЂ“ Sends and receives bits.Д®arly network development was chaotic. Network layer вЂ“ Manages devices addressing, tracks the location of devices on the network, and determines the best way to move data.Дata Link layer вЂ“ Provides the physical transmission of the data and handles error notification, network topology, and flow control. Transport layer вЂ“ Segments and reassembles data into a data stream. Session layer вЂ“ Responsible for setting up, managing, and then tearing down sessions between Presentation layer entities.

Presentation layer вЂ“ Presents data to the Application layer and is responsible for data translation and code formatting. The OSI reference model has seven layers:ДЄpplication layer вЂ“ The spot where users actually communicate to the computer. It also provides a framework for creating and implementing networking standards, devices, and internetworking schemes.

Rather, itвЂ™s a set of guidelines that application developers can use to create and implement applications that run on a network.

One of the greatest functions of the OSI specifications is to assist in data transfer between disparate hosts, meaning, they enable us to transfer data between a Unix host and a PC or a Mac, for example. The OSI reference model was created in the late 1970s, and the main reason the International Organization for Standardization (ISO) released the OSI model was so different vendor networks could work (communicate) with each other.

These layers will be explored in detail in this chapter. The OSI reference model breaks the network hierarchy into seven layers. The OSI reference model was created to simplify internetwork connectivity and speed time to market. Early development of networks was chaotic for numerous reasons.
