About Computer
A computer is an electronic device that processes data and performs tasks according to a set of instructions known as programs. Computer has become the need of every field now. Its application is necessary to save time and money.
Early Mechanical Computers
1. Abacus ( 3000 BC)
One of the earliest computing tools, used for basic arithmetic operations.
2. Pascaline 1642
Blaise Pascal invented this mechanical calculator, which could perform addition and subtraction.
3. Difference Engine 1822
Designed by Charles Babbage, this was a mechanical computer intended to compute polynomial functions.
4. Analytical Engine 1837
Also designed by Charles Babbage, it was a more advanced mechanical computer with features similar to modern computers, such as a central processing unit (CPU) and memory.
