Charles Babbage was English Mathematician and professor of the University of Cambridge in early 19th century. He is also known as father of computers because he gave the idea of modern computer. In 1988 Charles Babbage designed a machine that computed mathematical tables and complex arithmetic operations. This machine was known as Difference Engine. Difference Engine mainly consist of 3 parts; Arithmetic and logic unit (ALU), Control Unit (CU) and Memory Unit (MU).He made lots of efforts and resources to take out accurate results but due to lack of advance technology accurate part of this engine could not made.

So Charles Babbage lost interest and stopped working on Difference Engine and started working on his lifetime project in building a new machine. In 1833-34 he made machine know as Analytical Engine. Analytical Engine was considered the first computer of the world. This machine introduced the idea of computing numbers that is still in use. Analytical Computer consists of storage area and mill similar to today's memory and processor. He visualized the computer to be constructed with brass fittings and powered by steam. But unfortunately this machine could not build. Due to lack of funds and resources the computer who gave the idea of modern computer could not be made. Both machines made by Charles Babbage performed all arithmetic calculations and could store memory up to 20 decimals.
