  1. Lesson 9. Windows and the OSI Model

  2. Objective Briefly explain the function of each layer of the OSI model. List a Windows component in six of the seven layers and briefly explain the purpose of that component. Explain the difference between a connection-oriented and connectionless transport. Explain the purpose of name and address resolution.

  4. Microsoft Windows OSI Model Application Redirector Presentation Server Message Block (SMB) Session NetBIOS Transport NetBEUI TCP SPX Network IP IPX Data Link NDIS Physical Ethernet IEEE 802.3

  5. Microsoft Windows OSI Model Ethernet IEEE 802.3 1. Physical Token Ring IEEE 802.5 RS-232, etc

  6. Microsoft Windows OSI Model NDIS 2. Data Link Provides for error-free transfer of data frames between computers.

  7. Microsoft Windows OSI Model NDIS 2. Data Link The Network Driver Interface Specification (NDIS) provides protocol independence for network drivers.

  8. Microsoft Windows OSI Model TCP SPX 4. Transport IP IPX 3. Network TCP – Transmission Control Protocol IP – Internet Protocol SPX – Sequenced Packet Exchange IPX - Internetwork Packet Exchange

  9. Microsoft Windows OSI Model TCP SPX 4. Transport IP IPX 3. Network Required for Connecting to the Internet

  10. Microsoft Windows OSI Model TCP SPX 4. Transport IP IPX 3. Network Required for connecting to A NetWare Server (Called NWLink by Microsoft)

  11. Microsoft Windows OSI Model IP 3. Network Handles Address Resolution and Routing.

  12. Microsoft Windows OSI Model IP 3. Network Primary protocol for routing data on the Internet. Highly structured addressing scheme.

  13. Microsoft Windows OSI Model IPX 3. Network Protocol for routing data and resolving addresses on IPX/SPX network. IPX addressing scheme.

  14. IPX is to the IPX/SPX protocol as IP is to the TCP/IP protocol Both IPX and IP are in the Network Layer. Both handle Address Resolution and Routing.

  15. Microsoft Windows OSI Model TCP SPX 4. Transport Ensures that messages are delivered error-free and in the proper sequence.

  16. Microsoft Windows OSI Model TCP SPX 4. Transport Provide Connection-oriented Transport.

  17. Two types of message delivery services: Connection-oriented (TCP, SPX) Connectionless (UDP)

  18. Connection-oriented Transmission: Each packet is acknowledged as it is received. Every packet follows the same route. A very reliable form of delivery. A relatively slow form of delivery.

  19. Connectionless Transmission: Packets are sent via any available path. Packets are numbered because they may become lost or duplicated, or they may be received out of order. Faster than connection-oriented transmissions. Less reliable than connection-oriented transmissions.

  20. Microsoft Windows OSI Model TCP 4. Transport The connection-oriented transport protocol for the TCP/IP suite.

  21. Microsoft Windows OSI Model SPX 4. Transport The connection-oriented transport protocol for the IPX/SPX suite.

  22. Microsoft Windows OSI Model UDP 4. Transport A common connectionless protocol.

  23. SPX is to the IPX/SPX protocol as TCP is to the TCP/IP protocol. Both SPX and TCP are in the Transport Layer. Both are Connection-oriented Transport Protocols.

  24. Microsoft Windows OSI Model NetBIOS 5. Session NetBEUI 4. Transport 3. Network NetBIOS - Network Basic Input/Output System NetBEUI - NetBIOS Extended User Interface

  25. Microsoft Windows OSI Model NetBIOS 5. Session NetBEUI Allows two applications on separate computers to establish, conduct, and end a connection.

  26. Microsoft Windows OSI Model NetBIOS 5. Session NetBEUI Controls the Sessions in Windows-based networking. Name Resolution.

  27. Microsoft Windows OSI Model NetBIOS 5. Session NetBEUI 4. Transport A simple, fast, Microsoft-specific, non-routable Transport protocol for NetBIOS.

  28. Microsoft Windows OSI Model 6. Presentation Server Message Block (SMB) Controls the form used to exchange data between computers. Controls what we see on the screen.

  29. Microsoft Windows OSI Model Redirector 7. Application The window through which Applications access network services

  30. Microsoft Windows OSI Model Redirector 7. Application Server Message Block (SMB) 6. Presentation Makes network resources look and act like local resources.

  31. Microsoft Windows OSI Model Application Redirector Presentation Server Message Block (SMB) Session NetBIOS Transport NetBEUI TCP SPX Network IP IPX Data Link NDIS Physical Ethernet IEEE 802.3

  32. Briefly explain the function of each layer of the OSI model. Listed a Windows component in six of the seven layers and briefly explain the purpose of that component. Explain the difference between a connection-oriented and connectionless transport. Explain the purpose of name and address resolution.
