  3. The OSI Model

  4. The OSI Model

  5. The OSI Model

  6. Network HardwareOSI Physical Layer • When connecting computing equipment there are two major categories of media used: • Wired • Wireless

  7. Network HardwareOSI Physical Layer • Major Wired Technologies: • Twisted Pair • Coaxial Cable • Optical Fiber

  8. Network HardwareOSI Physical Layer • Twisted Pair • The most widely used medium for telecommunication • Can be utilized for both voice and data transmission. • Reduces crosstalk and electromagnetic induction. • Speeds ranges from 2 million bits per second to 100 million bits per second. • Unshielded Twisted Pair (UTP) • Shielded twisted-pair (STP)

  9. Network HardwareOSI Physical Layer • Coaxial Cable • Used for cable television systems, office buildings, and other work-sites for local area networks. • Copper or aluminum wire wrapped with insulating layer • Insulation helps minimize interference and distortion. • Speeds range from 200 million to more than 500 million bits per second.

  10. Network HardwareOSI Physical Layer • Optical Fiber • Glass fiber • Carries data by pulses of light. • Not affected by electromagnetic radiation. • Speed may reach trillions of bits per second. • can carry multiple multiple signals in a single strand.

  11. Network HardwareOSI Physical Layer • Wireless Networks • Not connected by cables of any kind • Avoids the costly process of introducing cables into to a building • Connects multiple buildings • Uses radio waves. • Physical level, (Layer 1), of the network structure.

  12. Network HardwareOSI Physical Layer • Wireless PAN (Personal Area Network) • Bluetooth radio • Infrared light • ZigBee • Intel "My WiFi" and Windows 7 "virtual Wi-Fi

  13. Network HardwareOSI Physical Layer • Wireless LAN (Local Area Network) • Uses an access point • Wi-Fi • Fixed Wireless Data

  14. Network HardwareOSI Data Link Layer • Wired Ethernet Hub

  15. Network HardwareOSI Physical Layer • Wireless LAN (Local Area Network)

  16. OSI Data Link Layer

  17. OSI Data Link Layer • MAC Addressing • Each hardware node, or device, has a unique Layer 2 address

  18. OSI Data Link Layer To view the MAC address of a node on a Windows machine, first open the command prompt by clicking the start button. Then in the search or run box type “cmd”

  19. OSI Data Link Layer While in the command prompt, type “ipconfig /all” which is the IP configuration utility. This should show the physical address, or MAC address:

  20. Network HardwareOSI Data Link Layer • Network Bridge

  21. Network HardwareOSI Data Link Layer • Wired Ethernet Network Switch

  22. OSI Network Layer

  23. OSI Network Layer

  24. OSI Network Layer • Network Addressing • Logical addresses • Internet Protocol (IP)

  25. OSI Network Layer To view the ip address of a Windows machine, first open the command prompt by clicking the start button. Then in the search or run box type “cmd”

  26. OSI Network Layer While in the command prompt, type “ipconfig” which is the IP configuration utility. This should show the IP address:

  27. Network HardwareOSI Network Layer • Wired Ethernet Network Router

  28. OSI Transport Layer

  29. OSI Transport Layer

  30. OSI Session Layer

  31. OSI Presentation Layer

  32. The OSI Model

  33. OSI Presentation LayerSecure Sockets

  34. The OSI Model

  35. Troubleshooting:Test the Physical Layer

  36. Troubleshooting:Test the Network Layer To view the gateway address of a Windows machine, first open the command prompt by clicking the start button. Then in the search or run box type “cmd”

  40. Troubleshooting:Test the Presentation Layer

  41. Troubleshooting:Test the Application Layer

  42. Learning Outcomes 1. List and describe the various types of network communications and network addressing. 2. List and define the different types of networks. 3. Describe different network topologies. 4. List and describe different network standards and protocols. 5. Describe wireless communication. 6. List and describe network hardware.
