The IBM RAMAC 350

Developed in 1956, the IBM RAMAC 350 was the first computer to have a magnetic disk drive similar to those used today. It weighed 1 tonne (1 ton) and had  50 disks that stored a total of 5 MB of data.…

Braille, developed by French inventor Louis Braille (1809–1852), is a famous example of binary code. It allows blind people to read by converting text into a pattern of raised dots embossed on paper. Each character is represented by a group of six dots, which can have the binary values of “raised” or “not raised”.…

The first integrated circuit was created in 1958 by American electrical engineer Jack Kilby (1923-2005). Before Kilby’s Invention, machines used vacuum tubes, which were bulky and unreliable. Kilby’s IC was based on tiny transistors, and all the parts were made on the one piece of material: the integrated chip was born.…

Greek inventor Hero devised a large number of machines. His steam engine, which he called an aeolipile, used the force of heated steam to make a metal sphere spin around. It was a clever idea, but never put to practical use.…

The D-wave quantum supercomputer has the same processing power as 100 million regular computers.
If 100 million computer chips were stacked on top of each other, they would be the same height as 23 Mount Everests.

Colossus, built in 1943, was a computer that had a fixed function: to break coded messages. The same was true of the ENIAC (Electronic Numerical Integrator And Computer), developed around the same time.
Changing the program of either of these computers involved rewiring the machine and physically pulling switches.…
