FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -On September 9, 1947, Harvard’s Mark II Aiken Relay computer was malfunctioning. After rooting through the massive machine to find the cause of the problem, Admiral Grace Hopper, who worked in the Navy’s engineering program at Harvard, found the bug. It was an actual insect.

Detailed explanation-2: -"First actual case of bug being found, ” according to the brainiacs at Harvard, 1945. The engineers who found the moth were the first to literally “debug” a machine. On September 9, 1947, a team of computer scientists and engineers reported the world’s first computer bug.

Detailed explanation-3: -At 3:45 p.m., Grace Murray Hopper records ‘the first computer bug’ in the Harvard Mark II computer’s log book.

Detailed explanation-4: -The story goes that she anecdotally discovered an actual moth trapped in the relay contacts inside her Mark II computer causing it to malfunction. Removing the bug fixed the glitch, and hence it became known as “debugging.”

Detailed explanation-5: -The terms “bug” and “debugging” are popularly attributed to Admiral Grace Hopper in the 1940s. While she was working on a Mark II computer at Harvard University, her associates discovered a moth stuck in a relay and thereby impeding operation, whereupon she remarked that they were “debugging” the system.
