A History of Abacus to Computers

Discover how the computer we know today was developed through time -

1. Abacus is made of beads and rods. It is a tool used to compute basic operations like addition and subtraction.

2. Blaise Pascal originally invented the Pascaline to help his father in collecting taxes. Its dials are moved to perform addition and subtraction.

3. Charles Babbage invented the Difference Engine to calculate polynomial functions. This device can also print the results in real-time.
4. John Napier invented Napier's Bones, which used the lattice method to simplify computation of products and quotients.

5. The Leibniz calculator is a decimal-based mechanical calculator invented by Gottfried Wilhelm Leibniz. It can perform four operations faster than the Pascaline.

6. Third-generation computers used integrated circuits instead of transistors. This allowed computers to be built smaller and run multiple applications.
