Then, in the 1960s, with the Cold War promoting an unprecedented scientific-technological race, notable progress was made in the field of electronics and it was possible to "integrate" computers, reducing their components. A possible mobile phone number list periodization of the process identifies them as second generation, from the invention of the transistor, and third generation, with the emergence of the integrated system.
Based on these new technologies, the multiprogramming operating system also emerged, capable of processing different mobile phone number list programs simultaneously and thus greatly reducing execution times. The emblematic company of all these transformations was the American International Business Machines Corporation ( ibm ), but they were still expensive projects.
With the 1970s came fourth-generation computers, whose revolutionary element was the invention of the microprocessor. Manuel mobile phone number list Castells argues that "the arrival of the microprocessor in 1971, with the ability to put a computer on a chip, turned the world of electronics, in fact the world itself, upside down"4. This gave rise to micro
