Development of computing
early 20th century
In 1932
during the Second World War
after the end of war
vacuum tubes technology with magnetic tapes
transistor technology
made much more quicly and cheaply
Uses very simple and widely avalaible ingrediend - sand. Silicon, which is obtained from sand is the material from which all modern electronic components are made
consumes very little power and very small and still delivers as much, or more, processing power
In 1947
Technology was limited by cost, size and energy comsumption
Univac - first computer: 2000 operations per second; 5200 vacuum tubes; weighed 13 metric tones
power computing was turned towards business and administrative problems
by a British mathematician, Alan Turing
Colossus
It's the first electronic computer. It used electricial relays or valves, punched tape was used to input data
were very large and slow. Perform calculations and also to store some of data while it was being processed
by Bush from the Massachusetts Institute of Technology in the USA
Differential Analyzer
the calculations were carried out using different sets of gears. It used electrical motors and it wasn't programmable
much more powerful and could perform large numbers of calculations much more quickly
Herman Hollerith in the USA
Tabulating Machine
a combination of punched card and mechanical gears
to speed up the processing of information from the US Census or population count
