Explain the OSI model with examples of each layer.
The OSI is open system interconnection model. It is a concept of
framework that describes the activities or functions of
telecommunication system. There are 7 layers in OSI model let us
discuss each
Layer 7: Application
An application layer is for shared communication protocols and
interface methods used by hosts in communication networks. It is
used in standard models
Layer 6: Presentation
It is the lowest layer which involves data structures and
presentation.
Layer 5: session
It provides mechanism for opening, closing and managing a session
between end-user application processes.
Layer 4: Transport
It deals with end to end communication over a network. It provide
logical communication between application processes and other
network components.
Layer 3: Network
In this data is transferred in the form of packets via logical
paths.
Layer 2: Data Link
It is a protocol layer for a set of telecommunication
protocols.
Layer 1: Physical
It deals with thephysical connectivity of two different stations.
It layers defines hardware, cabling, wiring.
