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...

Ethernet - (2) Summary on What we have studied in last Tutorial  ? :- Network involves connection of computers, Workstation and network devices such as routers, switches, and firewalls . Ethernet is most widely used Local Area Network ( LAN ) technology and is formally defines by IEEE 802.3 standard.  High speed Ethernet was developed in order to increase the connectivity speed between the terminals or computers in a particular network. Fast Ethernet is further sub-divided into two categories :- (1). Copper Cabled Ethernet & (2). Fiber Optic Cabled Ethernet. # Fiber optic Ethernet :-        Fibre cabled to Ethernet employes fibre optic cables for transmission of signals in which the electrical signals are converted to optical signals ( light signals ) for transmission through the cable which is made up of thin glass. These transmitted signals are again converted from light to electrical signals at the receiver e...
