History

In the prehistoric era, various efforts to discover the calculation instrument are considered as computer history. People in ancient times realized that muscles, jackfruit, ropes etc. Abacus, an ancient counting machine, is considered to be the first device in computer history. It was discovered in Babylon in 2400 BCE in Babylon. The composite machine is replaced by the calculator calculator frame. Abacus was created in 450/500 BC as a counting machine in Egypt or China.
