September 12th, 1958: Under the leadership of the Robert Noyce both (Intel founder), the integrated circuit was born, and soon found a microprocessor. However, due to the discovery of the microprocessor draws on the skills of the Japanese company, so in Japan about its patent does not recognize, because the Japanese did not get the proper benefits. 30 years, Japan was admitted, so that Japanese companies can be obtained from one part of the profits. But in 2001, the patent and lost efficiency.
in Western Europe from the Middle Ages into the Renaissance society PCT leather, throwing the world to promote the development of natural science skills, many lasting theocracy repressed creativity was suffering from an unprecedented release. In these Contemplative creative spark, manufacturing machines can help people care about is the brightest, most eye-catching one. Since then, one by a scientist in order to achieve this great Hu would like to make unremitting efforts. But limited to the level of technology at the time, the majority of test creation out defeat in the end, it will clear the common luck of the pioneers: often fallen not see the results of own efforts. Later, people enjoy such a sweet hour of the outcome can often be pleased to hear of them taste the taste of the cross of sweat and tears …
in September, 1943: Williams and Stibitz complete in order to “Relay Interpolator”, later named “Model II Re-lay Calculator “care about the machine. This is a programmable care, the same application the pace of tape input and value. It runs more reliable, each number of the seven relay, floating-point operations.

of care habits in 1972: 1972 has been called the fourth generation of care. Based on the LSI and later LSI. Machine regardless of efficacy of this period stronger, the smaller. At this point many people care about the machine began to doubt whether they can continue from large to small, in particular, is the subject of heat need to be answered whether the processing is complete. At the same time, many people began to explore the development of fifth generation regardless of the machine.
mechanical care of the birth of the machine
boil the the Toutai care about the machine (the ENIAC) in February 1946, was born in the United States. Put forward the pace of store American mathematician von ^ Neumann, lost in the U.S. Army, the 1943 research and production of the ENIAC, completed in 1946;

electronic care come out
Prior to this, you should care about the machine skills or focused on the mainframe as well as small areas of development. Follow the progress of LSI and microprocessor skills, regardless of the machine into the extraordinary the Liping Yi nearly skills stagnation gradually be broken. Intel Corporation released its microprocessors for personal users, this wave of 8080 and then finally surging Peng Pai up, while also urging the expulsion of a large amounts of the information age to engage in the influx of children, such as Stephen Jobs (History association Fen

in the birth of the care of mechanically run a hundred years and then followed by the rapid development of e-skills, regardless of machine began in the true sense of the transition from mechanical to the electronic age, electronic devices gradual transmutation into care machine the main mechanical components hanging down in a subordinate position. both the status of the transformation hour care unit officially began the transition from quantity to quality, thus leading to the formal advent of e-care machine. under this transition period Affairs:
in 1972: C-language development to complete its main designer is one of the developers of UNIX systems, Dennis Ritche This is a very strong language, especially loved by others.
3, the formation of crystals transistor development
desktop regardless of machine who found
