The layers associated with OSI model

1. ISO/OSI Model (7 Layers) Dr. Mohammad Adly

2. ISO/OSI Model ISO: International Standardization Organization OSI: Open System Interconnection Primary architectural model for networks Developed in 1983 Group of concepts Describes how devices send/receive data hop-to-hop end-to-end

3. Benefits of ISO/OSI Layered Model Divides the network communication process into l ayers to be easier to troubleshoot Allows multiple-vendor development through standardization of network components Various types of network hardware and software can communicate Layer separation makes changes in one layer do not affect other layers Layers can interact with each other

4. ISO/OSI Layers Application Presentation Session Transport Network Data Link Physical

5. Network Protocols NetBEUI IPX/SPX Apple Talk TCP/IP

6. NETBEUI NetBIOS Extended User Interface LAN Protocol Limited Performance Almost obsolete

7. IPX/SPX Standard Supports WAN Vendor Oriented Poor performance if used with other vendors

8. Apple Talk Standard Supports WAN Vendor Oriented Poor performance if used with other vendors

9. TCP/IP Standard Supports WAN Not vendor oriented Most widely used over Internet Mapped to OSI 7 layers
