Computer Bug

We often hear the term "bug" while using computers. /But what is a bug? /Well, in computer science, /a bug refers to an error in software or hardware. /In software, a bug is an error in coding /that causes a program to malfunction or to produce incorrect results. /Minor bugs, for example, a cursor that does not behave as expected /—can be inconvenient or frustrating, /but not damaging to information. /More severe bugs can cause a program to "hang" /and might leave-the user with no alternative but to restart the program, /losing whatever previous work had not been saved. /In either case, the programmer must find and correct the error by the process known as debugging. /Because of the potential risk to important data, /commercial application programs are tested and debugged as completely as possible before release.
