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.
Software testing typically includes handling software bugs – a defect in the code that causes an undesirable result. [11]: 31 Bugs generally slow testing progress and involve programmer assistance to debug and fix. Proactively identifying these bugs early in the development process helps reduce costs and prevent larger issues down the line.
In engineering, debugging is the process of finding the root cause of and workarounds and possible fixes for bugs.. For software, debugging tactics can involve interactive debugging, control flow analysis, log file analysis, monitoring at the application or system level, memory dumps, and profiling.
Situations which are frequently called computer glitches are incorrectly written software (software bugs), incorrect instructions given by the operator (operator errors, and a failure to account for this possibility might also be considered a software bug), undetected invalid input data (this might also be considered a software bug), undetected ...
Patches for other software are typically distributed as data files containing the patch code. These are read by a patch utility program which performs the installation. This utility modifies the target program's executable file—the program's machine code—typically by overwriting its bytes with bytes representing the new patch code. If the ...
A software performance regression is a situation where the software still functions correctly, but performs more slowly or uses more memory or resources than before. [3] Various types of software regressions have been identified in practice, including the following: [4] Local – a change introduces a new bug in the changed module or component.
In computing, a crash, or system crash, occurs when a computer program such as a software application or an operating system stops functioning properly and exits. On some operating systems or individual applications, a crash reporting service will report the crash and any details relating to it (or give the user the option to do so), usually to ...
Also simply application or app. Computer software designed to perform a group of coordinated functions, tasks, or activities for the benefit of the user. Common examples of applications include word processors, spreadsheets, accounting applications, web browsers, media players, aeronautical flight simulators, console games, and photo editors. This contrasts with system software, which is ...
