11. TCP/IPThe lingua franca of the Internet

12. A Very Brief History of TCP/IP and the Internet • Origins of TCP/IP start in the 1960s at MIT and with the creation of ARPANET • The original versions of TCP/IP as we know it today were created in the 1980s • In 1983, the DoD mandated that all of their computer systems would use the TCP/IP protocol suite for long-haul communications • ARPANET started with four nodes in 1969 and grew to just under 600 nodes before it was split in 1983. • ARPANET grew smaller and smaller during the late 1980s as sites and traffic moved to the Internet, and was decommissioned in July 1990.

13. History of TCP/IP and the Internet (continued…) • In 1986, the National Science Foundation (NSF) built a backbone network dubbed the NSFNET to interconnect four NSF-funded supercomputer centers • Originally for non-commercial use, the NSFNET eventually became the backbone of “the Internet”

14. Dramatic Growth of the Internet

15. TCP/IP – What is it? • Transmission Control Protocol/Internet Protocol • A suite of communications protocols • TCP/IP uses several protocols, the two main ones being TCP and IP. • TCP/IP is built into the UNIX operating system and is used by the Internet, making it the de facto standard for transmitting data over networks. • Even network operating systems that have their own protocols, such as Netware, also support TCP/IP

16. TCP/IP – What is it? • TCP/IP is roughly based on the OSI (Open Systems Interconnection) Model

17. Math Review • Decimal – Base 10 • 0,1,2,3,4,5,6,7,8,9 • Binary – Base 2 • 0,1

18. 1 1,000s 100s 2 10s 9 1s 5 __ __ __ __ __ __ __ __ Decimal Math • 1 • 10 • 100 • 1000 Ex. 1 X 5 10 X 9 100 X 2 1000 X 1 1000 + 200 + 90 + 5 = 1295

19. 1 8s 4s 1 2s 1 1s 1 __ __ __ __ __ __ __ __ Binary Math • 1 = 1 • 10 = 2 • 100 = 4 • 1000 = 8 Ex. 1 X 1 2 X 1 4 X 1 8 X 1 8 + 4 + 2 + 1 = 15

20. 1 8s 4s 0 2s 1 1s 0 __ __ __ __ __ __ __ __ Binary to Decimal Example • 1 = 1 • 10 = 2 • 100 = 4 • 1000 = 8 Ex. 1 X 0 2 X 1 4 X 0 8 X 1 8 + 0 + 2 + 0 = 10

21. Decimal to Binary • Example: 121d to Binary • Write out the places up to the number you are converting 128 64 32 16 8 4 2 1 1 1 1 1 0 0 1 __ __ __ __ __ __ __ 121-64=57 57-32=25 25-16=9 9-8=1 1-1=0

22. Practice • Convert Binary to Decimal • 1011 • 10101 • 11111 • 10000

23. Practice • Convert Decimal to Binary • 7 • 11 • 23 • 123
