MCQ IN COMPUTER SCIENCE & ENGINEERING

Detailed explanation-1: -A software bug is an error, flaw or fault in the design, development, or operation of computer software that causes it to produce an incorrect or unexpected result, or to behave in unintended ways.

Detailed explanation-2: -We can say that a mistake made by a programmer during coding is called an error, an error found during the unit testing in the development phase is called a defect, an error found during the testing phase is called a bug and when an error is found at an end user’s end is called as the failure.

Detailed explanation-3: -The word has been used in engineering since the nineteenth century. The word ‘bug’ actually is short for Bugbear. (sometimes found as Bugaboo). It’s meaning is much closer to ‘Gremlin’, where the people who worked on engineering prototypes often grew to suspect that the problems were due to malicious spooks.

Detailed explanation-4: -In computer technology, a bug is a coding error in a computer program. (We consider a program to also include the microcode that is manufactured into a microprocessor.) The process of finding bugs–before users do–is called debugging.

Detailed explanation-5: -When requirements are implemented in the wrong way, and resulting a deviation in customer specifications which leads to a defect. A bug is an error in the software that causes malfunction. A flaw in the product that reduces its usability of the product.
