Charles Babbage announces the analysis machine
Its general purpose was a machine that could be programmed by the user, capable of executing the desired instructions and commands. -
Period: to
First generation
First generation computers used vacuum tubes. A vacuum tube is a device that controls electric current flow in a high vacuum betwee electrodes to which an electric potential difference has been aplied. -
They started building ENIAC
Germans started to build the ENIAC. -
ENIAC was finished
The first computer in the world was finished. -
Period: to
Second generation
The second generation of computers consists of two types of devices, transistors, and magnetic core. The transistors helped to develop a better computer than the first generation computers consisting of vacuum tubes. They were smaller and cheaper to create. -
Period: to
Third generation
The computers of the third generation used integrated circuits (IC) instead of transistors. They were more reliable, even smaller in size and the consumed less electricity. They were invented by Jack Kilby. -
Period: to
Fourth generation
These computers used microprocessors instead of IC. These computers were very compact and thereby required a very small amount of electricity. This generation of computers had the first ''supercomputers''. -
Fifth generation (AI)
Its objective was the development of a new class of computers that would use artificial intelligence techniques and technologies
