LESSON 1:What Was the “Victorian Internet”?
Telegraph
•The Telegraph
•Invented in the 1840s.
•Signals sent over wires that were established over vast
distances
•Used extensively by the U.S. Government during the American
Civil War, 1861 - 1865
•Morse Code was dots and dashes, or short signals and long
signals
Famous Quote From
Sir Isaac Newton
LESSON 2:What Is the Internet?
Internet
•A network of networks, joining many
government, university and private computers together and providing an
infrastructure for the use of E-mail, bulletin boards, file archives, hypertext
documents, databases and other computational resources
•The vast collection of computer networks
which form and act as a single huge network for transport of data and messages
across distances which can be anywhere from the same office to anywhere in the
world.
Written by William F. Slater, III
1996
President of the Chicago Chapter of the
Internet Society
•The largest network of
networks in the world.
•Uses TCP/IP protocols and
packet switching .
•Runs on any
communications substrate.
Dr. Vinton Cerf,
Co-Creator of TCP/IP

LESSON 4:Internet Growth Trends
| Years | Information |
|---|---|
| 1997 | 111 hosts on Internet |
| 1981 | 213 hosts |
| 1983 | 562 hosts |
| 1984 | 1,000 hosts |
| 1986 | 5,000 hosts |
| 1987 | 10,000 hosts |
| 1989 | 100,000 hosts |
| 1992 | 1,000,000 hosts |
| 2001 | 150 – 175 million hosts |
| 2002 | over 200 million hosts |
| (2010- 2013) | about 80% of the planet will be on the Internet |
LESSON 5: IP Addressing
•An IP address is a unique global address for
a network interface
•Exceptions:
–Dynamically assigned IP addresses
(à DHCP, Lab 7)
–IP addresses in private networks
(à NAT, Lab 7)
•An IP address:
- is a 32 bit long identifier
- encodes a network number (network
prefix) and a host number
Network
prefix and host number
- The network prefix identifies a network and the host number identifies a specific host (actually,interface on the network).
| network prefix | host number |
