Here I describe all of OSI MODEL layer and their purposes.
And also discuss about their protocol.which protocol are using in OSI MODEL. By reading this slide your basic concept in OSI MODEL will be clear and easy.

3. Established in 1947, the International Standards Organization (ISO) is a
multinational body dedicated to worldwide agreement on international
standards. An ISO standard that covers all aspects of network communications is
the Open Systems Interconnection (OSI) model. It was first introduced in the late
1970s.
OSI MODEL
Note:
ISO is the organization.
OSI is the model.
5. Physical
Layer
Transfer Binary Bit stream from source to destination as a electrical signal.
Encode bits into
signals
Translation of
bits into signals
Synchronization
of bits
Data Rate
Topology
Transmission mode
Purpose
6. Physical Layer Protocol
Digital Subscriber Line.
Integrated Services Digital Network.
Infrared Data Association.
Universal Serial Bus.
Bluetooth.
Controller Area Network.
Ethernet.
7. Data Link
Layer
Send blocks with necessary
Responsible for error-free
transmission over the physical media
Assures error-free data submission
to the Network Layer
purpose
The data link layer is responsible for moving
frames from one hop (node) to the next.
8. Data Link Layer Protocol
LLDP Link Layer Discovery Protocol
PPP Point-to-Point Protocol
Ethernet
FDDI Fiber Distributed Data Interface
Frame Relay
ITU-T G.hn Data Link Layer
9. Network Layer
purpose
The network layer is responsible for the
delivery of individual packets from
the source host to the destination host.
Address translation from
logical to physical
Routing of data
Based on priority
Best path at the time of transmission
10. CLNP Connectionless Networking Protocol
EGP Exterior Gateway Protocol
IPv4 Internet Protocol version 4
IPv6 Internet Protocol version 6
IPSec Internet Protocol Security
ARPAddress Resolution Protocol
RIP Routing Information Protocol
Network link Layer protocol
11. The transport layer is responsible for the delivery
of a message from one process to another.
Transport Layer
SegmentationOf
Reassembly
Connection
Control
Error Control
Purpose
12. Transport Layer protocol
ESP Encapsulating Security Payload over IP or IPSec
SCTP Stream ControlTransmission Protocol
SPX Sequenced Packet Exchange
TCPTransmission Control Protocol
UDP User Datagram Protocol
DCCP Datagram Congestion Control Protocol
13. Session Layer
The session layer is responsible for dialog
control and synchronization.
Synchronization between sender and receiver
Assignment of time for transmission
Start time
End time etc.
Purpose
14. Session Layer protocol
NetBIOS, File Sharing and Name Resolution protocol - the
basis of file sharing with Windows.
NetBEUI, NetBIOS Enhanced User Interface
NCP NetWare Core Protocol
NFS Network File System
SMB Server Message Block
15. Presentation Layer
The presentation layer is responsible for translation,
compression, and encryption.
Translation
Data translation
Encryption
Purpose
17. Application Layer
The application layer is responsible for
providing services to the user.
Purpose
• User application to network service
interface
• File request from server
• E-mail services
• etc.
