Peculiar data of the computers In this article we will speak on some peculiar data of the computers, I imagine that sometimes you have asked yourself in date invented the computer or that it invented the computer, because this and you will know plus it. When the first computers were created? The first generation of computers includes from year 1945 to year 1958, time in which the electronic technology era with bulbs or vacuum tubes, and the communication was in terms of level lower than it can exist, that is known like machine language. Characteristics: * They were constructed with electronics of valves * programmed in machine language SECOND GENERATION. From 1958 to 1965, within this generation the evolution of the computers enough is marked, that is to say, is remarkable the difference, reason why also it has his characteristics. This system was not very effective since constantly the information because was lost the magnetic drum nontapeworm protective coating 1). – The bulbs are replaced by transistors. 2). – The physical size of the computers in a 50%.
3 Falls approximately). – Also the quality control of the conditioned air falls. 4). – The programming is internal and it is possible to be supported all the programs of process. 5). – The speed of operation is of microseconds. 6).
– In software (the High-level languages) THIRD GENERATION. It includes/understands from 1965 to 1970, within this generation the physical size of the computer is reduced to the maximum and has the following characteristics: 1). – The transistor is replaced by the microtransistor. 2). – The physical size of the computers Falls from 60 to a 70%. 3). – The quality control of the conditioned air also falls. 4). – The memory follows internal by means of magnetic cores. 5). – The speed of process continues being of microseconds. 6). – In software (Operating system) FOURTH GENERATION. It includes/understands of 1971 until 1980, within this generation the physical size of the computers is reduced from 80 to a 90% and have the following characteristics: 1). – The microtransistor is replaced by integrated circuits which have the function of 64 microtransistors. 2). – The quality control of the conditioned air is null or almost null. 3). – The speed of process is of nanoseconds 1X10-9. 4). – One works the multiprogramming and the local and remote teleprocess. 5). – In software (LISP, PROLOG) FIFTH GENERATION. Although he is not totally correct to say that the present computers are of the fourth generation, is already spoken of the following one, that is to say the villa. It includes/understands of (1981 – 200? ). In this generation already the input devices of the PC as well as of all the software of the same are modernized.
