A software bug is an error or flaw in a computer program that causes it to produce incorrect or unexpected results. Bugs can occur for various reasons, such as mistakes in the code, incorrect logic, or unexpected interactions between different parts of the software. They can lead to crashes, data loss, or other issues that affect the user experience. Identifying and fixing bugs is an essential part of the software development process. Developers use various tools and techniques, such as debugging and testing, to locate and resolve these issues. Regular updates and patches are often released to improve software performance and eliminate known bugs.
