OSI Model (Open System Interconnection) has been
developed by International Organization for
Standardization (ISO). It is an abstract
description for layered communications and
computer network protocol design. It is a 7 layer
architecture. All these seven layers work
together to transmit the data from one system to
another. Each layer have different functions to
work.

LAYERS OF OSI MODEL
  • APPLICATION LAYER  It is The Topmost Layer of
    OSI model. users interact directly with
    applications that work at layer 7. Some examples
    of application layers are Google Chrome,
    Firefox, Safari, Skype, Outlook, Office.
  • PRESENTATION LAYER  Presentation layer is also
    called the Translation layer.  The data from the
    application layer is translated according to the
    format to transmit over the network. 
  • The functions of the presentation layer are  
  •  Translation 
  •  Encryption 
  •  Compression

  • SESSION LAYER  Session layer is responsible for
    the security and authentication.  This Layer also
    ensure setup, coordination (how long should a
    system wait for a response) and termination
    between the applications at each end of the
    session 
  • The functions of the session layer are
  • Session establishment, maintenance and
    termination 
  • Synchronization 
  • Dialog Controller

  • Transport Layer  This layer takes data from the
    above layer and breaks it into smaller units
    called Segments and then gives it to the Network
    layer for transmission. It is responsible for the
    End to End delivery of the complete message 
  •  The functions of the transport layer are
  • Segmentation and Reassembly 
  • Service Point Addressing

  • NETWORK LAYER  Network layer works for the
    transmission of data from one host to the other
    located in different networks. It Transmit the
    data in the form of packets. It selects the
    shortest path to transmit data. 
  • The functions of the Network layer are
  •  Routing 
  • Logical Addressing

  • DATA LINK LAYER  The Data Link Layer provides
    node-to-node data transfer between two directly
    connected nodes. It also handles error correction
    from the physical layer.  It transmit the data as
    the frames 
  • The functions of the data Link layer are 
  •  Framing 
  • Physical addressing 
  •  Error control 
  •  Flow Control 
  • Access control

  • PHYSICAL LAYER  It is the lowest layer of OSI
    Model.  It is responsible for the actual physical
    connection between the devices . This layer
    contains the data in the form of bits 
  •  The functions of the physical layer are 
  •  Bit synchronization
  •  Bit rate control 
  • Physical topologies 
  • Transmission mode
