What number system do computers use?
What number system do computers use?
Binary is a number system that uses only two digits: 0 and 1. Computers use binary to represent data because it's easy to implement with electronic circuits (on/off states).
Who first conceptualized program control in computing?
Who first conceptualized program control in computing?
Charles Babbage, considered the 'father of computing', conceptualized the first mechanical general-purpose computer, the Analytical Engine. His ideas laid the groundwork for program control, even though the machine wasn't fully built.
