The document outlines the six generations of computers from the 1940s to present. The first generation used vacuum tubes and punched cards for data storage. The second generation introduced transistors, making computers cheaper, faster and smaller. The third generation saw the development of integrated circuits and operating systems. The fourth generation brought the microprocessor and personal computers. The fifth generation focused on interconnecting all types of devices. The sixth generation is characterized by developments in communication technologies, miniaturization, and the widespread use of networks for distributed computing and multimedia.

1. 1981-1990
1940-1952
First Generation
The vacuum tubes
were the main
element of
ordenadores.Was
slow and very
bigs.They started to
use the binary system
to represent the
information. The used
was military and
cientific.The language
was the language
machine.They used
progamaction of
punch cards to store
information.
Fifth Generation
From this generation and no
difference in the technology used
to create the machines, but the way
it is used. The fifth generation is
differentiated by the
interconnection between all types
of computers, devices and
networks (integrated).Begin to
create parallel operation schemes .
Using components for very large
scale integration (VLSI ) .Using
language of fifth generation.
Integration of data, image and
voice ( multimedia environments ).
Developments in Artificial
Intelligence, Robotics and Expert
System .
1964-1971
Third Generation
Chpis invented in 1964 , and
integrated circuits
, computers were even
smaller , more rapid and
more efficient . The
computers consume less
electricity. Desarollaron
operativosy systems
multiprogramacion.Begins
to use semiconductor
memories and magnetic
disks .
1952-1964
Second Generation
The vacuum valve is
replaced by the
transistor.The
computers were
cheaper and faster
and smaller. PCs are
used by other type
of people. The
computers started
to had new
programming
languages .The PCs
begin to use other
internal and
external memories.
1971-1981
Fourth Generation
In 1971 appears the microprocessor. It
uses technology to integrate large scale LSI circuits . Through This
technology , more circuits are Placed
Within the same chip, tasks.Created
That staff perform different computers
and microcomputers . A single
integrated circuit contains the control
unit and the arithmetic / logic unit .
As external storage unit using the
diskette (floppy disk) . Supercomputers
They created new programming
languages ​.
1990-Present
Sixth Generation
It is characterized by developments in
communications technology .
The miniaturization of components in the machines,
and cost reduction lead to high capacity.The systems
of the previous generation supercomputers are
outpaced by new workstations. The use of nets is
common, with high speeds and service integration
quality video, voice and other real-time multimedia
data. With the expansion of networks, emerged
parallel processing on massive scales in which an
infinite number of computers cooperate performing a
task (Distributed Computing and Clusters or clusters
of computers).
Internet invades the domestic world generating new
alternatives in all human activities.
