Software error

A bug refers to a program error or software error. A bug is a technical problem or error in a software or computer program. It is an unexpected behavior or malfunction that causes the program not to work as intended.

The term “bug” was first used by Grace Hopper when she was working on a computer in the 1940s and noticed a problem caused by an insect that had entered the computer and affected its functionality. Since then, the term “bug” has been commonly used to refer to software errors.

Bugs can have various causes, for example

  • programming errors,
  • insufficient test coverage,
  • unexpected user input or
  • Incompatibilities between different components.

Bugs can manifest themselves in various ways, such as crashes, erroneous output, performance problems, or security vulnerabilities.

Bugs are usually fixed by software developers by identifying the faulty code, correcting it, and then retesting the program to ensure that the bug has been fixed and the program works as expected.
