What did Grace Hopper find?

Computer programmer Grace Hopper helped develop a compiler that was a precursor to the widely used COBOL language and became a rear admiral in the U.S. Navy.

When did Grace Hopper find the bug?

September 9, 1947
On September 9, 1947, the world’s first computer bug was recorded. But this was no ordinary ‘software bug’. It was a real-life moth that was causing the issues with the computer’s hardware. This “first actual case of bug being found” was recorded by computer scientist Grace Hopper.

What was the name of the computer Grace Hopper was working on when a bug was discovered?

Mark II Aiken Relay computer
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.

What is bug in computers?

A software bug is an error, flaw or fault in a computer program or system that causes it to produce an incorrect or unexpected result, or to behave in unintended ways. A program that contains many bugs, and/or bugs that seriously interfere with its functionality, is said to be buggy (defective).

Operators traced an error in the Mark II to a moth trapped in a relay, coining the term bug. This bug was carefully removed and taped to the log book.

What was the bug type that coined the term bug for CS hint it is from a publicized article by Grace Hopper?

That bug was an actual moth that shorted out the computer, she helped popularize the widely used term “computer bug.” We found/detected a bug [=glitch] in the program.

Where did the term bug come from?

Operators traced an error in the Mark II to a moth trapped in a relay, coining the term bug. This bug was carefully removed and taped to the log book. Stemming from the first bug, today we call errors or glitches in a program a bug. Hopper did not find the bug, as she readily acknowledged.
