History of Electronic Communications: Past and Present

this is the history of electronic communications

1. HISTORY
1753 a proposal submitted to a Scottish magazine suggested
running a communications line between villages
comprised of 26 parallel wires, each wire for one letter of
the alphabet.
1832 the first successful data communications system was
invented by Samuel F. B. Morse called the telegraph.
1833 Carl Friedrich Gauss developed an unusual system based
on a five-by-five matrix representing 25 letters (I and J were
combined).

2. HISTORY
1840 Morse secured an American patent for the telegraph
1844 the first telegraph line was established between Baltimore
and Washington, D.C., with the first message conveyed
over this system being “What hath God wrought!”
1849 the first slow-speed telegraph printer was invented
1850 Western Union Telegraph Company was formed in
Rochester, New York, for the purpose of carrying coded
messages from one person to another.
1860 high-speed (15-bps) printers were available

3. HISTORY
1874 Emile Baudot invented a telegraph multiplexer, which
allowed signals from up to six different telegraph machines
to be transmitted simultaneously over a single wire.
1875 The telephone was invented by Alexander Graham Bell
and, unfortunately
1899 Guglielmo Marconi succeeded in sending radio (wireless)
telegraph messages.
1920 The first commercial radio stations carrying voice
information were installed.

4. HISTORY
1930 Konrad Zuis, a German engineer, demonstrated a
computing machine.
1940 Bell Telephone Laboratories is given credit for developing
the first special purpose computer using electromechanical
relays for performing logical operations.
1946 J. Presper Eckert and John Mauchley at the University of
Pennsylvania are given credit by some for beginning
modern-day computing when they developed the ENIAC
computer.

5. HISTORY
1949 the U.S. National Bureau of Standards developed the first
all-electronic diode-based computer capable of executing
stored programs.
1950 Computers used punch cards for inputting information,
printers for outputting information, and magnetic tape
reels for permanently storing information.
1951 The UNIVAC computer was built by Remington Rand
Corporation, was the first mass-produced electronic
computer.

6. HISTORY
1960 Batch-processing systems were replaced by on-line
processing systems with terminals connected directly to the
computer through serial or parallel communications lines.
1969 The Internet began to evolve at the Advanced Research
Projects Agency (ARPA).
1970 Microprocessor-controlled microcomputers were
introduced.
1980 Personal computers became an essential item in the home
and workplace.
