A "computer bug" or "software bug" is a term for an unintentional programming mistake or defect in computer software or hardware. Bugs arise from human error in hardware designs or somewhere in the chain of software tools used to create computer applications, firmware, or operating systems.
In the computer world, a bug is an error in a software program. It may cause a program to unexpectedly quit or behave in an unintended manner. For example, a small bug may cause a button within a program's interface not to respond when you click it.
A software bug is a bug in computer software. A computer program with many or serious bugs may be described as buggy. The effects of a software bug range from minor (such as a misspelled word in the user interface) to severe (such as frequent crashing). Software bugs have been linked to disasters.
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.
Software bugs are unexpected outcomes or errors in computer software. They manifest as undesired behavior, crashes, or incorrect output and stem from errors in the software development process during design, coding, or testing.
What Does Bug Mean? In IT, a bug refers to an error, fault or flaw in any computer program or a hardware system. A bug produces unexpected results or causes a system to behave unexpectedly. In short it is any behavior or result that a program or system gets but it was not designed to do.
OVERVIEW. Software bugs are the errors, issues, or flaws found in the software application that result in their malfunctioning and unexpected performance. These bugs manifest in many forms, like coding mistakes, logical errors, and design flaws.
Essentially, anything that causes the programmer’s intentions to not be fully carried out can be considered a bug, unless the programmer is trying to make the computer do something it wasn’t designed to do.
A problem that causes a program to produce invalid output or to crash (lock up). The problem is commonly erroneous logic that misdirects the computer to a place in the program where...
