BASIC’s popularity really took off in the 1970s and 1980s, when home computers first became available. Most machines came with a version of BASIC, which became many people’s introduction to programming. The syntax of the language was straightforward and easy to learn, and allowed people to write software to help them in their businesses, or as a hobby.…

An analogue computer stores and processes data by using physical quantities, such as weight, length, or voltage, as opposed to a digital computer, which stores data as binary code on its hard drive. While digital computers are limited to two values (0 and 1), every single unit of analogue data can give precise answers.…

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.…

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.…

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.…
