Transmission Media - 1 Objectives : Cable characteristics Various types of Cables  Fiber optic cable  Connectors of fiber optic cable  Cabling Standard - EIA/TIA 568A and 568B  Straight cabling & Cross Cabling   Introduction :-       Networking involves connection of computers, workstations and peripheral devices. Networking hardware involves all the peripheral devices,interface cards and other equipment such as cables and wires that are used to establish a network connection. Wire is a single, cylindrical strand of metal conductor with low resistance to the current flow. Cable can be defined as a bunch of wires bound together which may be or insulted. You can connect these devices either using physical transmission medium or using wireless transmission medium. Physical transmission media involves the use of wires and cables. (1) Characteristics of Cables  :       Before selecting a ca...

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...
