What is a Bug

Definition of a Bug

A bug in computer terms refers to an error, flaw, or fault in a software program or system that causes it to produce an incorrect or unexpected result. Bugs can cause a program to crash, behave unexpectedly, or function improperly.

How Bugs Occur

Bugs can occur due to various reasons, such as human error during programming, incorrect logic, or unexpected user inputs. In many cases, bugs are identified during testing and debugging phases, but some bugs can remain undetected until after software release.

Impact of Bugs

Depending on the severity of a bug, it can have minor or major effects on the functionality of a program. Some bugs might be small annoyances, while others can lead to serious security vulnerabilities or system crashes.

How to Fix Bugs

Fixing a bug is often referred to as debugging. Developers typically use various testing methods to identify bugs and then apply patches or code modifications to resolve the issues.
