The development of computers was accelerated. Its use began in the field of science, step to business, in less than 50 years invaded daily life and today is practically necessary in any home.

They were machines that occupied entire rooms. The data and programs were stored in a rotating magnetic drum. The data was loaded by means of perforated cards and processed by bulbs, glass tubes that contained electrical circuits and that generated a lot of heat.
Main Machines
2.Second generation
The transistors replaced the bulbs. Computers were smaller, faster, versatile, durable and economical. The data was stored on magnetic disks. The software was improved, facilitating its programming and use. It spread the use in companies.
The STRETCH is one of the computers built by transistors by the IBM company, thought to be a hundred times faster than the 704 models of the first generation of computers of that company.
Main characteristics
3.Third generation
Integrated circuits were used that allowed to have hundreds of transistors in a small space.
Computers became smaller, more powerful and more efficient. More flexible programs appeared. The main computers were the IBM 360, PDP-8 and PDP-11.
Main characteristics
4.Fourth generation
The microchip became widespread. This resulted in machines of smaller size and cost, increasingly powerful.
Personal computers were born, the first was the "APPLE I" developed in 1976. In 1981 the company IBM launched its PC with an open architecture that allowed the integration of components from other manufacturers.
Main characteristics
5.Fifth generation
The parallel use of several microprocessors was developed simultaneously, increasing the processing capacity.
It also improves the interaction with the machine through the graphical interface. the first virtual reality games and laptops appear.
The evolution of computers is revolutionized the world, as these provide us with various amounts of facilities. You can still develop computers even more, the only thing that is needed is to continue working on how to improve them in such a way that they are practically unbeatable.
A wonderful round of applause for my friends are:
