Ábaco
The first mechanical type calculator was devised in Babylon. This mechanical device called abacus consisted of a system of bars and pulleys with which different types of arithmetic calculations can be performed. -
Oughtred presents the slide rule
the English mathematician William Oughtred used the newly invented logarithms to make a device that simplified multiplication and division. It consisted of two joined graduated rulers sliding one over the other. -
First adding machine
The French mathematician and philosopher Blaise Pascal was nineteen years old when he built the world's first adding machine, using a cogwheel gear as counters. The device carried 1 automatically when reaching the tens and could also be used to subtract. -
first programmer
was a British mathematician. She is considered the first programmer, since she wrote the manipulation of symbols -
First programmable digital computer
This machine was programmed by a series of punched cards that contained data or instructions which passed through a reading device, were stored in a memory and the results were reproduced by molds. -
Perforated cards
Data storage method consisting of Strip of paper a long strip of paper in which holes are made to store the data. -
First keyboard adder
A sequence of digits could be added by pressing successive keys. Each key raised a vertical axis to a certain height and the sum was indicated by the total height. -
Empty tubes
Vacuum tubes or Vacuum valves. Electronic devices consisting of a Steel or Glass vacuum capsule, with two or more electrodes between which the Electrons can move freely. -
UNIVAC
It is considered the first commercial computer developed in the United States. Conceived by computer pioneers John W. Mauchly and John P. Eckert, -
IBM's Transistor Calculator
it was IBM's first commercial machine to use transistors. -
higher level languages
The third generation of computers emerged with the development of integrated circuits (silicon chips) in which thousands of electronic components are placed in a miniature integration -
Micro computers
Microcomputer is a small computer, with a microprocessor as its central processing unit CPU. Microcomputers became popular from 1970 to 1980 -
fifth generation
His objective was the development of a class of computers that would use artificial intelligence techniques at the machine language level and would be capable of solving complex problems -
sixth generation of computers
It could be considered that the sixth generation of computers has its beginning at the end of the 20th century and at the beginning of the 21st century, without an end date since it is considered still under development. The devices generated have the common feature of being intended for personal consumption, which has led to them being simplified but at the same time capable of performing various functions.
