UNIVAC (acronym for Universal Automatic Computer ), the first computer built for non-military purposes, was born in 1941. It weighed more than 7 tons and could make 1000 calculations per chinese overseas australia data second. It was not much more than a modern scientific calculator, but it revolutionized its time, as did ENIAC (Electronic Numerical Integrator and Computer), a little more modern (1946), which occupied almost 170 m2 and could make about 5000 sums per second.
In the early 60s the first Mainframe (Central Computer) was born, defined as a supercomputer that could make an immense amount of simultaneous calculations. For many years, large companies have invested huge amounts of money in the purchase and maintenance of these computers, protagonists and central axes of their calculation centers.
But technology continued to evolve, and in the early 80s the PC (Personal Computer) was born. The “dumb” terminals were dying out, and along with servers smaller than the Mainframe but with great parallel processing capacity, which could also collaborate with each other (server farms), the “Client-Server” era was born. Investments decreased.
