After many years of working, Charles created a machine called a "Difference Engine" which had the capabilities to add and subtract numbers but did not include an ability to multiply or divide. He used government funding to spend 8 years working on the prototype until it finally became tangible.
Babbage moved on from his spectacular creation and made something even more grand which he entitled an "Analytical Engine" this was a lot more powerful than his previous endeavor and even included multiplication and division capabilities. Parts he used for this mechanism are even used in computers that are around today such as a Central Processing Unit.
An intel Central Processing Unit
Many many steps had to be taken to get anywhere close to the computers we have today. The first computer that included a screen and other graphic interphase features wasn't released until 1975. Innovations such as microprocessors, typing, internal memory, and printing were all just steps that led to what we have today. For many years the main focus was solely based on speed not an update on the technology involved with it.
Eventually computers were progressed and perfected by innovators like Bill Gates, Steve Jobs, Larry Page, and people at IBM to achieve the incredible product we have today with endless capabilities and uses. Computers are currently a huge part of our daily lives. We should all be thankful for Charles Babbage's ingenuity because it truly changed our lives.
