1. TCP/IP Model of Networking

2. TCP/IP Model - Layers Access Internet Transport Application

3. TCP/IP and Protocols Application Layer HTTP, HTTPSFTP, TFTPDHCP, DNSPOP3, SMTP, IMAP

4. TCP/IP and Protocols Transport Layer TCPUDP

5. TCP/IP and Protocols Internet Layer IPICMP

6. TCP/IP and Protocols Access Layer EthernetWiFiPoint to Point

8. TCP/IP and Functions Application Layer Data is created and usedClient and/or Server Software

9. Client Server Networks

11. TCP/IP and Functions Transport Layer TCP – 3 Way HandshakeUDP – Request, Send

12. 3 Way Handshake Request OK, Here are my Rules OK, Fine OK, Here are my Rules Data

13. TCP/IP and Functions Internet Layer IP - Addressing of NodesIP – Best Path DeliveryICMP – Diagnostic and ID

14. TCP/IP and Functions Access Layer Local Delivery

16. TCP/IP and Encapsulation Application Layer Produces DataEncryption, Compression

17. TCP/IP and Encapsulation Transport Layer Segments DataPort Numbers Added

18. Well Know Port Numbers ApplicationPort Number FTP20, 21 Telnet23 SMTP25 DNS53 TFTP69 HTTP80 HTTPS443 DHCP546, 547

19. TCP/IP and Encapsulation Internet Layer Adds IP AddressesNow called a Packet

20. Socket IP Address: Port Number Or URL: Port Number https://10.140.100.63:5009

21. TCP/IP and Encapsulation Access Layer Adds MAC Address for local deliveryNow called a Frame

23. TCP/IP and Dencapsulation Access Layer Reads MAC AddressChecks for ErrorsShould I read it?

24. TCP/IP and Decapsulation Internet Layer Reads IP AddressShould I read it?

25. TCP/IP and Decapsulation Transport Layer Reads Port NumberTCP – Put message togetherWhich App should I send it to?

26. TCP/IP and Decapsulation Application Layer Uses Data

27. There and Back Again
