500 BCE
The Abacus
It was invented in Babylon 500 b.C, they were boards to count, it was not a computer because it did not have the capacity to store information, but with this instrument transactions were made in several cities of antiquity. They were very used in China. -
Pascal calculator
It was created in 1642 by the young Frenchman BLAISE PASCAL, seeing that his father had problems to keep a correct account of the taxes he charged, he invented a calculating machine that worked based on gears, the same one that Pascal called it with on behalf of PASCALINA. -
Leibniz multiplication machine
Gottfried Wilhelm von Leibniz adds to the machine invented by Blaise Pascal the functions of multiplication and division. -
creation of the Arithmometer
Charles Xavier Thomas de Colmar He invented a calculator that could carry out the four basic mathematical operations (add, subtract, divide and multiply). It was consolidated as the most remarkable invention of the 19th century. -
Babbage analytical and differential machine
In 1822 Charles Babbage created a differential machine capable of developing polynomials but several disadvantages in the pieces of this machine made it fail, after this failure in 1833 Babbage creates the analytical machine which was capable of doing all mathematical operations and being programmed by half of cards of perforated cardboard and keep a huge amount of figures, this is why Charles Babbage is considered the father of the computer. -
Hollerith's tabulating machine
Herman Hollerith created a system based on punch cards, the system used for the United States in a national survey in 1990, this system, ordered and enumerated the punch cards that contained the data of the sensed people, was the first automated use of a machine. When seeing these results Holerith founds a company of tabuladoras machines that later happened to be the International Business Machines (IBM). -
Period: to
First generation of the computer
The MARK I and the UNIVAC I stand out -
MARK I
In this first generation stands out the creation of the MARK I computer that was developed by Howard Aiken, in this period the Second World War is developed by which many projects were left unfinished. -
UNIVAC I
In 1951 the first computer for commercial use was built which was called UNIVAC I, this computer was built to be used in the census office of the United States, it was replaced in 1889 by the Hollerith Tabulating Machine. -
Period: to
Second generation of the computer
The most remarkable of this second generation is the replacement of the use of vacuum tubes by transistors which made computers smaller and faster. -
PDP-1
It was the first computer in the PDP series of Digital Equipment, produced for the first time in 1960. It is famous for being the most important computer in the creation of hacker culture at MIT, BBN and elsewhere. The PDP-1 was also the original hardware where the first computerized video game in history was played, Steve Russell's Spacewar. -
Period: to
Third generation of the computer
The greatest achievement of this generation is the use of integrated circuits (silicon chips), this made computers smaller and faster, they also consumed less electricity and more efficient. -
PDP-8
It was the first commercially successful minicomputer, with more than 50,000 units sold. It was created by Digital Equipment Corporation (DEC) in April 1965. It was characterized by its large storage capacity and its small volume compared to other computers of the time. -
The era of microprocessors
In this epoch known as the fourth generation of the computer (1971-1981), it was characterized by the miniaturization of electronic circuits, and the consequent creation of various microprocessors. The small size of the chip microprocessor made possible the creation of personal computers, one of the most recognized processors of the time was the INTEL 4004. -
Period: to
Fourth generation of the computer
The most important thing in this generation is the invention of the microprocessor which united the integrated circuits in a single block.
In this generation appear the first microcomputers which were manufactured by the companies APPLE and IBM. -
TRS-80
Also affectionately or mockingly known as the "Trash-80" ("Garbage-80"), it was the designation for several lines of microcomputer systems produced by Tandy Corporation and sold through its Radio Shack stores in the late 1970s and in the 80. -
EPSON HX-20
In general, it was the first portable computer, announced by Epson in November of 1981, although it did not start selling until 1983. Acclaimed by BusinessWeek magazine as the fourth revolution in personal computing. and it is for this reason that it is highly valued among collectors. -
Period: to
Fifth generation of the computer
In these last two generations advances in technology have been occurring very quickly, in these years the companies responsible for building computers had great advances in microelectronics and software advances, in this period the "social networks" Internet, and starts artificial intelligence. -
Period: to
Sixth generation of the computer
We enter the era where robotics and artificial intelligence is consolidated, where 90% have as a "basic need" to use the Internet service and therefore have a computer, we can work, study, entertain, communicate and an infinite of activities in these appliances, who would think that all this would arise from the creation of an abacus in Antiquity. -
The ease, comfort and entertainment
From 1990 to date we have been seeing that computers are smaller, more versatile, now the Internet is an indispensable tool both in work centers and at home, almost 90% of the population makes use of some time on the internet , and therefore of a computer. -
Technology replacing man?
We are entering an era where computers can develop capacities almost similar to human beings, we have already seen robots that can play a football match, we hope that the technological advancement in the world of computer science and computing will make things easier for us as well as So far he has been doing it. -
MacBook Air
MacBook Air is an ultra-slim laptop. There are two models of MacBook Air, 11 "and 13"; with weight of 1.08 kg and 1.35 kg respectively (depending on their configuration). This is a laptop that uses flash storage. It is characterized by being one of the thinnest of all time.
