Charles Babbage designed a machine called the Analytical Engine 200 years ago. If it had been built this machine would have been the first modern computer. -
First Generation Computer

The 1st generation of computers was from 1940 to 1955. Computers were powered by vacuum tubes and used magnetic drums to store data and memory. -
Second Generation Computer

Then in 1956, the second generation of computers hit. The vacuum tubes were no longer the best thing for running a computer, the latest component to replace the vacuum tubes is a transistor. -
The Third Generation computer

The era of transistors was short lived because in 1964, integrated circuits became the next great thing in developing semiconductor technology. -
Fourth Generation Computer

The 4th generation is still the present generation of computers. When microprocessors where invented in 1971, the era of mass usage of computers began! The 4th generation was started by the Intel 4004 chip. Microprocessors have thousands of integrated circuits on one silicon chip. -
