History of Computers:
Between 1820 – 1833 British mathematician Charles Babbage designed a machine called the Analytical Engine. It was capable of storing one thousand 50 digit numbers, could evaluate conditional statements, and take in custom inputs that affected the output.
Although it never got built during his time, the ideas behind Babbage’s Analytical Engine can still be seen in today’s computers.
A French mathematician named Ada Lovelace wrote algorithms for the machine and she is known as the first ever computer programmer.
In the middle of the 20th century, electronic computers began to be built by different people around the world.
Initially this began as part of an effort during World War II, but soon became made in an effort to support business operations.
The first home computer was built in 1981
