What is the Internet?
The Internet is a large collection of computers all over the world that are
connected to one another in various ways. The Internet is one of the most amazing
technological advancements ever.
On the Internet you can find the following resources and tools:
- Periodicals, documents, research reports
- E-mail
- Downloadable software applications
- Discussion groups
- Chat
- Interactive Games
- Shopping
There are a variety of ways that computers can be connected to a
network. The most common way is through a Network Interface Card (NIC) card
installed on the computer's motherboard. Computers that are connected to
each other over a 30 mile or less radius are part of a Local Area Network (LAN).
All of RVCC's computers are connected together to form a fairly complex LAN. The
Internet is a Wide Area Network (WAN) as it encompasses the entire world.
History of the Internet
The Internet began as a cold war military project in the 1960s. The
Department of Defense (DOD) wanted to make sure that if a nuclear attack
decimated this country, surviving officials could still communicate. A network
was needed that could not be centralized. If it were centralized, then the
"Commies" would target that site, effectively destroying the network.
The word Internet means "collection of networks." It would take a
collection of networks to keep communications alive the post apocalypse. The
Advanced Research Projects Agency (ARPA) was charged with the task of
decentralizing.
1966 –
- Paul Baran of the Rand corporation came to the conclusion that a packet
switched network would best suit the military’s needs. Baran had been
commissioned by the air force to research this topic. Packet switching
involves breaking down data into tiny packets. Each packet takes a different
route through the network and is reassembled at the other end in the correct
order. Routers at different locations determine the path of each packet on a
packet by packet basis using routing algorithms.
- By this time, users had been able to timeshare on a mainframe. If
connected to a dumb terminal, both users could access the computer at the
same time. This idea led to the feasibility of a global network. The main
roadblock was the telephone system used to connect the computers, not the
fact that the machines used different operating systems. Thus, dedicated
lines had to be used to connect the computers together. Modems would have to
wait a little longer. During this time, computers could only communicate
through leased telephone lines. Once a connection was established, all data
traveled down the single path. This technology was called circuit switching.
1969 —
- Baran’s dream becomes a reality. ARPANET goes online with four machines
connected by wires.
- The machines were connected at UCLA, Stanford Research Institute, UCSB,
and the University of Utah.
- The machines used agreed upon protocols in order to communicate. Other
wise there would have been no way for the computers to understand/interpret
the data sent to them.
- Use of Interface Message Processors (IMP) [Honeywell 516 mini computer
with 12K of memory] developed by Bolt Beranek and Newman, Inc. (BBN)
1973 —
- Vinton Cerf of Stanford writes a new Internet communications protocol,
TCP/IP. Transmission Control Protocol/Internet Protocol cleared up problems
evident in the first ARPANET. In the first ARPANET, there were no
concessions in case one computer could not communicate with the other. TCP
includes rules that computers on a network use to establish and break
connections; IP includes rules for routing of individual data packets.
A poem written by Cerf
Like distant islands sundered by the sea,
We had no sense of one community.
We lived and worked apart and rarely knew
That others searched with us for knowledge too.
Distant ARPA spurred us in our quest
And for our part we worked and put to test
New thoughts and theories of computing ar;
We deemed it science not, but made a start.
But could these new resources not be shared?
Let links be built; machines and men be paired!
Let distance be no barrier! They set
That goal: design and build the ARPANET.
15 nodes and 23 hosts online
Nodes:
- UCLA
- Stanford Research Institute
- UCSB
- U. of Utah
- BBN
- MIT
- Rand Corp.
- SDC
- Harvard
- Lincoln Lab.
- Stanford
- U. of Illinois, Urbana
- Case Western Research U.
- Carnegie Mellon
- NASA-Ames
Around this time E-mail became very popular. This came as a surprise to many
whom believed the Internet would be great for sharing research. Even 25 years
ago, people were communicating informally via networks in the same relaxed
writing style as today.
1974 —
- 62 hosts on ARPANET
- Cerf coins the term 'Internet'
1976 --

Ellis, and Steve Bellovin.
1981--
- Arpanet expands to include over 200 networks.
1983 —
- The University of Washington came up with the idea of the Domain Name
Server. This allowed users to type in the name of the computer they wanted
to connect to rather than the IP address.
- 500 computers on Arpanet.
- ARPANET split into ARPANET and MILNET; the latter became integrated with
the Defense Data Network created the previous year.
1984—
- The National Science Foundation gets into the act of networking. They
wanted to set up super computing centers where people could purchase time
for research. The NSF infrastructure was upgraded more often than was
ARPANETs. Soon the NSFNET overtook the ARPANET as far as its importance in
the current world of networking.
- The NSF decided to let the corporate world continue its infrastructure
upgrading. Companies like MCI and IBM provided the new equipment. Soon the
NSF’s backbone was running T1 lines, 1.544 mbps. At this point ARPANET was
still running at 56K.
- More sites began coming online since speed was faster. By the end of 1984
there were 1,024 computers on NSFNET/ARPANET.
- Number of hosts breaks 1,000
- Moderated newsgroups introduced on USENET (mod.*)
1985 –
- America Online goes online.
- On March 15th, Symbolics.com is assigned the first registered domain.
Other firsts: cmu.edu, purdue.edu, rice.edu, ucla.edu (April); css.gov
(June); mitre.org, .uk (July)
1986--
- Internet Engineering Task Force (IETF) meets for the first time. The IETF
is a self organized group that makes technical contributions to the
engineering of the Internet and its technologies. Today the IETF is the main
body that develops new Internet standards.
1987 –

- Network Solutions Inc. Reports that it is registering 2,000 domain names a
month.
- In August, AOL hits the one million member mark.
1995—
- The NSF decides it will no longer allow access to its backbone. It would
sell its backbone to major companies who would in turn sell connections to
the public. This allowed the NSF, a government organization, to leave the
networking business they never intended to be a part of, and allowed the
huge growth in Internet commercialization that we’ve seen in recent years.
While the NSF was running the show, commercialization was kept to a minimum
due to government regulations. By the end of the year, most Fortune 500
Companies would have their own Web sites.
- 5,000,000 computers on the Internet.
- It is no longer free to register domain names with Network Solutions. The
costs are now $100 for the first two years and $50 for each additional year.

1996:
- The Communications Decency Act is passed. It would later be found
unconstitutional because of its inability to define what is and is not
decent.
- 9,000,000 computers on the Internet.
- MCI’s backbone is upgraded to 622MBPS.
- Network Solutions drops 9,000 domain names from its database after
repeated attempts to collect payment from the names’ owners.

Network Access Points
There are only four US companies with true Internet access. If
you look at Figure 1-7 in the book you will see the four NAPs on the Internet
backbone. By looking at Figure 1-9 you can see how you obtain Internet access.
More than likely it is through a company that purchased access from one of the
four NAPs rather than from one of the NAPs itself. These companies are called
Internet service providers. They generally provide access to the Internet as
well as other services such as Web design. Companies such as AOL and MSN buy
access to the Internet from the four big shots. The closer you are to the top of
the access food chain, the faster your access will be.
Access is measured in bits per second. Figure 1-10 displays
information about the different types of services you can buy and the speed they
provide.
