Open system Interconnection  (OSI) Model - 1 Open System Interconnection (OSI) Model  :-            Open System Interconnection (OSI) Model was developed by the International Standards Organization (ISO) describes the flow of information from one computer to another. OSI model is also called ISO OSI Reference Model. It is conceptual model that has seven layers. Physical, Data link, Network, Transport, Session, Presentation and Application are the seven layers of OSI model. Each layer performs distinct functions on the data in accordance with the precious layer functions. The application, presentation and session layers are called as Upper layers.  7 layers of OSI model           All the layers of the OSI reference model use different protocols. Protocol defines the procedure that is to be followed during data transmission. It is the set of specified rules and standards used to transmit data fr...

Transmission Media - 7 Summary on What we have studied on last tutorial  :- Single Mode :  A type of cable that has only single strand of glass fiber with a thin diameter. This is a 9/125 micrometer fiber cable. The diameter of a core glass is approximately 9 micrometer. Multi mode :   A type of cable that contains a glass fiber with a larger diameter. Multiple modes of light signals can be propagated through it. This is 62.5/125 micrometer fiber cable. A connector is a mechanical device that is attached to the fiber optic cable or the light source. Straight tip ( ST) :  It was developed by AT&T. A popular connector used with the fiber optic cables and used in Gigabit Ethernet or backbone. Joins individual fibers to optical devices. Sub Miniature Type A (SMA) :  Defines a connector that uses two individual connectors for each fiber strand. Subscriber/Standard Connector (SC) :  A type of low-cost connector used in 100 Base-FX fibe...
