History Timeline: 1965
Internet, as we know it today, is much different than when it
was first developing. The early history of the creation
of the Internet is full of exciting advances in government and
university technology. Below is a brief timeline of some of the
major events in the first 20 years of Internet development. These
key events helped to shape the Internet of today.
The First Twenty Years of the Internet
Advanced Research Projects Agency (ARPA) sponsors a study on "cooperative network of time-sharing computers." A
TX-2 at MIT Lincoln Lab directly linked to a AN/FSQ-32 at System
Development Corporation in California using a dedicated 1200bps
created ARPANET by connecting 4 hosts at UCLA, UCSB, SRI, and
the University of Utah. The four hosts were connected
using their developed Network Control Program (NCP). ARPA was responsible "for
the direction or performance of such advanced projects in the field
of research and development as the Secretary of Defense shall,
from time to time, designate by individual project or by category,” according
to the Department of Defense.
1972: ARPA changes to DARPA (Defense Advanced
Research Projects Agency), the central research and development
the Department of Defense that was established as a separate defense
agency under the Office of the Secretary of Defense.
switching nodes and internetwork gateways appear. Packet switching
refers to protocols in which messages are broken
up into small packets and each packet is transmitted individually
across the net, and may even follow different routes to the destination.
When the packets reach their web destination they are reassembled
into the original message.
was developed at AT&T.
UUCP has aided the ability to facilitate the exchange of electronic
link using UUCP technology between the University of North Carolina
and Duke University causes the birth
of Usenet. Usenet
is defined by Dictionary.com as “a messaging system that
uses a computer network, especially the Internet, to transfer messages
organized in thematic groups.”
first TCP/IP implementations appear. TCP/IP is made up of a few
components. According to Yale
University, “IP is
responsible for moving packet of data from node to node. IP forwards
each packet based on a four byte destination address (the IP number).
The Internet authorities assign ranges of numbers to different
organizations. The organizations assign groups of their numbers
to departments. IP operates on gateway machines that move data
from department to organization to region and then around the world.” Also
TCP “is responsible for verifying the correct delivery of
data from client to server. Data can be lost in the intermediate
network. TCP adds support to detect errors or lost data and to
trigger retransmission until the data is correctly and completely
1980: By this time there are about 213 hosts
making up the Internet, versus the original 4 in 1969.
requires the use of TCP/IP and MILNET, the Defense
Informations Systems Agency splits from ARPANET.
1983: In just a
few years the number of hosts on the Internet more than doubles
October, Domain Name System (DNS) is introduced and the number
of hosts has reached over 1,000. According to Webopedia, “an
Internet service that translates domain names into IP addresses.
Because domain names are alphabetic, they're easier to remember.
The Internet however, is really based on IP addresses. Every time
you use a domain name, therefore, a DNS service must translate
the name into the corresponding IP address.”
