Definition of Bug:

  1. Annoy or bother (someone).

  2. A small insect.

  3. A miniature microphone, typically concealed in a room or telephone, used for surveillance.

  4. An insect of a large order distinguished by having mouthparts that are modified for piercing and sucking.

  5. Unexpected problem with a software or hardware that causes it to falter or fail, or is just annoying to the user. Hardware bugs are remedied by a new circuit design, software bugs are usually debugged by including a small program (called a patch) to bypass the problem. Patching provides temporary relief, until an updated (supposedly bug-free) version of the software is available. Patches and updates, however, often generate their own bugs and thus perpetuate the debugging-updating cycle.

  6. An error in a computer program or system.

  7. Conceal a miniature microphone in (a room or telephone) in order to monitor or record someones conversations.

A bug is an unexpected problem with software or hardware. Typical problems often arise due to external interventions in the operation of the program that were not foreseen by the developer. Minor bugs can cause minor issues such as screen crashes or unexplained error messages that do not significantly affect the user experience. Fatal errors can not only affect software and hardware, but can also have unintended effects on connected devices or firmware and corrupt data files.

A software bug is a problem that leads to or results in invalid output. Most errors are due to the human factor.

This is a coding error in a computer program.
