A. Alan Turing
B. Charles Babbage
C. J. Presper Eckert
D. John Mauchly

Answer & Solution
Option: B
Explanation : Charles Babbage is called the father of computer or computing. He invented Difference Engine(1822) and Analytical Engine(1833).
Difference Engine(1822) was a calculating machine. It was more than a simple calculator. Like modern computers the Difference Engine had storage, where data could be held temporarily. it uses only arithmetical addition and get rid of the need for multiplication and division. The Difference Engine can only do one operation. Difference Engine was a digital device, it operate on discrete digits and these digits were decimal (0–9), they are represented by positions on toothed wheels. When one of the toothed wheels turned from 9 to 0, it move the next wheel to advance one position, carrying the digit.
Analytical Engine(1833) was considered the first general purpose computer. It was much more than a calculator. It contained an Arithmetic Logic Unit(ALU), basic flow control, and memory. Analytical Engine has many essential features found in the modern digital computer. It was programmable using punched cards. The Analytical Engine had a ‘Store’ where numbers and results could be held like memory in modern computers. Analytical Engine also has a separate ‘Mill’ where the arithmetic processing was performed like CPU(Central Processing Unit) in modern computers. It was also capable of functions like conditional branching, iteration, microprogramming and many others others.
