FIRST GENERATION:

During this period, the people doesn’t know the capacities about computers. They started to be selled in Unated States, at the 50 the centuryes. The characteristics about this first generation were: They used tubes to procces the information. They used perfored tubes to save the information They were very big Binary system be started to use

SECOND GENERATION

In this period, the computers evolved reducing his size, many valvules were replaced by cheapest and better valvules. Also many companies were created. Some characteristics are: The programs have improved They used little magnetic rings to save the information The transitors were smaller and faster

THIRD GENERATIONS

This generation was very important because a new type of circuits integred. Ageing it be smaller and faster, then they don’t disprend as heat as other generations.

FOURTH GENERATION

During this generation, microproccesors appeared, an important. Microcomputers based on these circuits are extremely small and cheap, so their use extends to the industrial market. Some characteristics were: Microprocessors were created More circuits were added at a chip Magnetic rings were substituted at for chips

FIFTH GENERATION

This generation is the most important, software have improved a lot. International competition for market dominance arises. The characteristics were Personal microcomputers were created. Macro computers were created.

2000-01-01 13:46:50

SIXTH GENERATION

This generation is the actual, a lots of computers, brand, companies were created, microtransitors, processors, power supplies have evolved. In this generation all is faster and faster. New methods appeared to save information, and to process all the dattas.
