At p.m., Grace Murray Hopper records 'the first computer bug' in the Harvard Mark II computer's log book. The problem was traced to a moth stuck between relay contacts in the computer, which Hopper duly taped into the Mark II's log book with the explanation: “First actual case of bug being. The term ‘bugs in a computer’ had been used before, but after Grace Hopper wrote in her diary “first actual case of bug being found” the term became really popular, and that’s why we are.
Sep 09, · 66 years ago today, on the 9th September, , operators of the Mark II Aiken Relay Computer being tested at Harvard University, found something curious trapped between points at Relay #70, Panel F. A moth. A note made at the time explains, this was the “first actual case of bug being found. On September 9, , computer scientist Grace Hopper reported the world’s first computer bug. A bug is a flaw or glitch in a system. Thomas Edison reported “bugs” in his designs as early as the s, but Hopper was the first to identify one in a computer.
A software bug is an error, flaw, failure or fault in a computer program or system that causes it to produce an incorrect or unexpected result, or to behave in unintended ways. The process of finding and fixing bugs is termed "debugging" and often uses formal techniques or tools to pinpoint bugs, and since the s, some computer systems have been designed to also deter, detect or auto. ENIAC (/ ˈ ɛ n i æ k /; Electronic Numerical Integrator and Computer) was the first electronic general-purpose computer. It was Turing-complete, digital and able to solve "a large class of numerical problems" through reprogramming.. Although ENIAC was designed and primarily used to calculate artillery firing tables for the United States Army's Ballistic Research Laboratory (which later Coordinates: 39°57′08″N 75°11′28″W .
