History of Data Communication

Through a series of technological developments from the 19th century onward, data communication evolved from simple wired telegraph connections to today's global digital networks. Key early developments included Samuel Morse's telegraph system in the 1840s, Alexander Graham Bell's telephone in the 1870s, and the transistor and integrated circuit in the 1960s. This led to packet-based networks in the 1960s-1980s and the emergence of the Internet and World War in the 1990s, allowing near-instantaneous digital communication worldwide. Wireless technology also advanced, starting with radio broadcasts in the 1920s and evolving to modern cellular and WiFi networks.

History of Data

Communication
Arzath Areeff

INTRODUCTION
The key technology of the information age is communication. Data communications is a global area of
study. Though data communication may seem a relatively new innovation, the history of data
connections dates to the early 19th century.
Through an array of technological developments that enjoyed commercial, government and military
contributions, data communication evolved from simple wired connections to a robust global exchange
of information.
What is Data Communications?
Exchange of digital information between two digital devices is data communication

HISTORY TIMELINE OF DATA COMMUNICATION


1837

Alexander Bain patented a Printing Telegraph


Telegraph service used by the Great Western
Railway, an endorsement that allowed the
service to expand across the nation

1843

1876

The development of early


telecommunications The Radio is invention by
Guglielmo Marconi, and it is make great
developments in communication technology.

Samuel Morse exhibited a working Telegraph


System
According to the History of Computing, data
communication has its earliest roots in
telegraph system. An account of data
communication history posted by
telecommunications experts at General
Telecom, LLC also points to a telegraph patent
that inventor Charles Wheatstone filed that
same year

1895

Improving on the telegraph, according to the


History of Computing, Alexander Graham Bell
introduced the Telephone

1947

These technologies are expanded by U.S.


government with its launch of a
communications-oriented satellite, and the
first facsimile transmission over standard
telephone lines occurred four years later

1958

1962

According to the History of Computing, the


development of Internet Protocol (IP) marked
a significant milestone in data communication
history. Within the following decades, early
packet communication technologies like
Asynchronous Transfer Mode (ATM), Frame
Relay and Integrated Services Digital Network
(ISDN) emerged as a viable solution for
commercial and high-end residential data
needs

The Transistor introduced by Bell Labs


This is a device that found integration in
myriad subsequent electronic products.

After the first Fax Transmission, the


modulation of data into sound for
transmission across telephone lines spread in
popularity for several years. Though
modulation/demodulation, or modem,
technology continued to carry slower data
traffic for the remainder of the 20th century

1969

1991

More than 1 million servers had come online


using Internet Protocol technology, and the
World Wide Web emerged as the primary
component of the Internet by the mid-1990s

Wireless

Like wire data communication technology at the same time the wireless communication
technology also developed,
It is developed rapidly during World War I
By 1921, the first commercial radio voices broadcast in the form of modulated radio waves,
In 1974, the Federal Communication Commission (FCC) began allocating wireless spectrums for
wireless communication, and wireless companies began integrating radio packet data as early as
1984.
This technology evolved into the various digital wireless packet data protocols used into the 21st
century.
