Who is known as the 'father of computing'?
Answer: A) Charles Babbage
Charles Babbage is recognized as the 'father of computing' because he conceptualized the Analytical Engine in the 19th century, which was a mechanical general-purpose computer. This design laid the foundation for modern computers, incorporating features like an Arithmetic Logic Unit (ALU), basic flow control, and integrated memory. Although his engine was never completed during his lifetime, its architecture introduced the concept of programmability. Ada Lovelace wrote algorithms for it, earning her the title of the 'world's first programmer'. Babbage's contributions are fundamental to hardware architecture and computational theory. -
