trials to lift up the cable failed so a new attempt was made from
the Great Eastern in March 1866. It took five months - then the
first message was transmitted across the Atlantic. |
HOW
IT ALL BEGAN ...
1866
- The first fully functional telephone cable laid across the Atlantic.
Queen Victoria and the UK President exchange messages using the cable.
1943 - Alan Turing builds Colossus, the world’s
earliest computer used to decipher German messages during the second
world war.
1945 - Vannevar Bush first Director of the National
Science Foundation introduces the memex. The micro-film based memex
enabled the user to link together related pieces of information for
rapid retrieval ... the first web concept.
1948 - Mathematician Claude Shannon published A Mathematical
Theory of Communication enabling the calculation of the information-carrying
capacity of any channel and introducing the word ‘bit’ to
describe a piece of binary information, which underpins all information
and modern communications (internet) system theories.
1958 - After the launch of Sputnik, the first earth-orbiting
satellite, President Dwight D. Eisenhower, creates the Advanced Research
Projects Agency (ARPA) to develop space and military programs which
included the creation of a new global computer and
communications system.
1961 - Researcher, Leonard Kleinrock publishes a paper
on packet-switching theory, and ARPA scientists consider communication
links in terms of passing active packages of information around rather
than routing them through fixed circuits.
1962 - Computer scientist, Paul Baran, studying the
survivability of communications under nuclear attack, describes a distributed
computer network for the first time. This, a network built in a number
of nodes, was revolutionary in its use of messages split into blocks,
each taking a different path to its destination - in essence a packet-based
network as considered by Kleinrock.
1965 - Ted Nelson coins the term ‘hypertext’
- text that can be read in a non-linear fashion - by following a series
of links between related sections of material. By far the biggest hypertext
application is the world wide web.
1967 - ARPA computer scientist, Roberts designs a fast,
decentralised network built on dial-up telephone lines. The
Arpanet Age
