The computer age and the industrial society

 The industrial revolution can be divided in three periods with each 100 years.
- 1770-1870 steam engine
- 1870-1970 electronics age
- 1970-present computer age

Its a surprise, that espeically the electronics age took 100 years in total. During this period, computer technology wasn't availableff but only prototypes were created. The starting year of the computer age was 1970, which is also the starting time of the Unix clock. Early Amateur clubs were:

Amateur Computer Society 1966, U.S.
Amateur Computer Club (ACC), founded in 1973, U.K.
Homebrew Computer Club from 1975, U.S.

These clubs have emerged from former ameteur electronics clubs. Early attempt to build computers were based on electronics circuits. Modern transistors and IC were assembled together with the goal to build a pocket calculator which can add and subtract numbers.

Since the 1970, computer technology has emerged quickly. The idea of a computer itself remained stable over decades. So it makes sense to summarize the duration from 1970-2070 as the computer age. During this period, the computer was the most influential technology available. The latest iteration of computers is able to control robots and process natural language, but the technology is also based on computers which consists of hardware and software.

In contrast, former electronics from 1870-1970s was working with a different principle. Electronics is based mostly on physics, it has to do with using electrical current for connecting components. Even if a computer is also an electronics device, it is operating with a different self understanding. Computers are special sort of electronics device, which complex.
