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.
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 ...
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.
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 ...
Computer graphics is a sub-field of computer science which studies methods for digitally synthesizing and manipulating visual content. Although the term often refers to the study of three-dimensional computer graphics, it also encompasses two-dimensional graphics and image processing.
The Apple "goto fail" bug was a duplicated line of code which caused a public key certificate check to pass a test incorrectly. The GnuTLS "goto fail" bug was similar to the Apple bug and found about two weeks later. The GnuTLS bug also allowed attackers to bypass SSL/TLS security. [61]
For example, humans have faults but not bugs, and a server crash due to natural disaster is not a bug. In addition to or instead of defect , some use: error, flaw or fault . Engineered systems is a broad classification encompassing but not limited to: software , computer hardware , electronics , circuitry and machinery .
Unsuited video card (graphics card) drivers. Drivers that have values that the graphics card is not suited with. Overclocking beyond the capabilities of the particular video card. Software bugs in the application or operating system. The differing cases of visual artifacting can also differ between scheduled task(s).
