On September 9, 1947, a team of computer scientists reported the world’s first computer bug—a moth trapped in their computer at Harvard University.

What are the bugs of computer program?

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.

What are the bugs in software testing?

A “Bug” is a most unwelcomed word in the software development process. A bug indicates a fault, error or failure in the software/system being built that produces unexpected results. A bug identified needs to be tracked and fixed to ensure optimum quality in the software/system being developed.

Which of the following is an example of software failure in software engineering?

Software failures may be due to bugs, ambiguities, oversights or misinterpretation of the specification that the software is supposed to satisfy, carelessness or incompetence in writing code, inadequate testing, incorrect or unexpected usage of the software or other unforeseen problems.

When was the first computer bug ever found?

After finding a moth inside the Harvard Mark II computer on September 9th, 1947 at 3:45 p.m., Grace Murray Hopper logged the first computer bug in her log book. She wrote the time and the sentence: “First actual case of bug being found”. Nowadays, the term “bug” in computer science is not taken literally, of course.

What are some examples of common software bugs?

If you have any doubts as to how common software bugs are, just do a news search for “software bug” or “software error” … Some bugs may cause only trivial problems, but flight control software and software for medical equipment are examples of things that simply cannot be allowed to fail due to programming errors.

How much do software bugs cost the economy?

A 2002 study commissioned by the National Institute of Standards and Technology ( referred to here) found that software bugs cost the US economy $59.5 billion every year (imagine the global costs…). The study estimated that more than a third of that amount, $22.2 billion, could be eliminated by improved testing.

Why is it important to identify computer bugs?

In the digital era, computer bugs can affect our lives, the economy of a nation and even the well-functioning of society in general. As the internet of things gradually invades all aspects of our environment, the importance of identifying and preventing computer bugs grows exponentially.
