What bug did Grace Hopper find in her computer?
When they opened the computer’s hardware, they found a moth. The trapped insect had disrupted the electronics of the computer. Among the team who found the first-reported computer bug was computer-language pioneer Grace Hopper.
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).
What is an example of a bug on a computer?
A bug is a general term used to describe any unexpected problem with hardware or software. For example, Grace Hopper logged and taped a moth bug in a log book that caused issues with the Mark II.
Where did Grace Hopper grow up?
New York City
Hopper was born on December 9, 1906 in New York City. As a child, she attended a preparatory school in New Jersey. Later, she enrolled at Vassar College.
Why are computer glitches called bugs?
The term “bug” was used in an account by computer pioneer Grace Hopper, who publicized the cause of a malfunction in an early electromechanical computer. 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.
What did Grace Murray Hopper do for a living?
Grace Brewster Murray Hopper was a computer pioneer and naval officer. She received a master’s degree (1930) and a Ph.D. (1934) in mathematics from Yale. One of the first three modern “programmers,” Hopper is best known for her trailblazing contributions to the development of computer languages.
When did Grace Murray Hopper retire from UNIVAC?
Nicknamed “Amazing Grace” by her subordinates, Hopper remained on active duty for 19 years. She retired from UNIVAC, a division of Sperry Rand, in 1972. Hopper became a well-recognized figure toward the end of her life.
When did Grace Murray Hopper invent COBOL?
In 1959 COBOL (short for “common business-oriented language”) was introduced as the first standardized general business computer language. Although many people contributed to the “invention” of COBOL, Hopper promoted the language and its adoption by both military and private-sector users.
Why was Calhoun College named after Grace Murray Hopper?
On Feb. 11, President Peter Salovey announced that he and the Yale Corporation had voted to change the name of Calhoun College, one of the university’s undergraduate residential colleges, to honor alumna Grace Murray Hopper. Grace Brewster Murray Hopper was a computer pioneer and naval officer.
