Difference Engine
It is a mechanical calculator that calculates mathematical sums without error, this is important because it start off the next inventions. Invented by Charles Babbage -
Vacuum Tubes
The Vacuum tube is about the same size as a human thumb, it has been utilized for almost every computer and calculating machines. It operates by using large amounts of electricity to heat a filament inside the tube until It was hot enough to turn cherry red, the consequence of this is the release of electrons into the tube.
