A Defect is any process output, product, or service that does not meet customer requirements.

Why is it called bug in software?
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 is a defect?
noun. a shortcoming, fault, or imperfection: a defect in an argument; a defect in a machine. lack or want, especially of something essential to perfection or completeness; deficiency: a defect in hearing.
What are types of defects?
Common Types of DefectsArithmetic Defects.Logical Defects.Syntax Defects.Multithreading Defects.Interface Defects.Performance Defects.
What is difference between defect and issue?
An issue can be a bug or a defect. The term issue is often used with clients to indicate that the problem not necessarily is faulty code. A defect can also be a bug, but for me a defect is a piece of code that works- but doesn’t do what it is expected to do.
What is bug life cycle with example?
A Defect life cycle, also known as a Bug life cycle, is a cycle of a defect from which it goes through covering the different states in its entire life. This starts as soon as any new defect is found by a tester and comes to an end when a tester closes that defect assuring that it won’t get reproduced again.
Does all software have bugs?
No, there are always more bugs. It does however mean that the software has been tested as thoroughly as possible within the time constraints of the project, with the team that you have available. There is no such thing as bug free software.
What is defect example?
The definition of a defect is an imperfection or lacking that causes the person or thing with the defect to fall short of perfection. An example of a defect is a genetic condition that causes weakness or death. An example of a defect is faulty wiring that results in a product not working.
What is a system defect?
A system defect (informally known as a bug) is a flaw or weakness in the system or one of its components that could cause it to behave in an unintended, unwanted manner or to exhibit an unintended, unwanted property.

What was the first computer bug called?
“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.
Why do softwares have defects?
There are many reasons for Software Bugs. The most common reason is human mistakes in software design and coding. Once you know the causes for Software Defects it will be easier for you to take corrective actions to minimize these defects.
What is a defect life cycle?
Defect life cycle, also known as Bug Life cycle is the journey of a defect cycle, which a defect goes through during its lifetime. It varies from organization to organization and also from project to project as it is governed by the software testing process and also depends upon the tools used.
What is bug and defect?
“A mistake in coding is called Error, error found by tester is called Defect, defect accepted by development team then it is called Bug, build does not meet the requirements then it Is Failure.” … In other words Defect is the difference between expected and actual result in the context of testing.
What is the difference between a defect and a failure?
The difference between a defect and a failure is: a defect is an error or bug in the software. A failure, however, happens when a defect produces the wrong results. … Defects are also results of error in logic or coding. Failures may also be the results of human error.
