A software patch is a piece of code designed to update, fix, or improve a computer program or its supporting data. Patches are often released to address security vulnerabilities, bugs, or performance issues, ensuring that the software runs smoothly and securely. These updates can be small, addressing specific problems, or larger, introducing new features. Regularly applying software patches is essential for maintaining the integrity of systems and protecting against potential threats, making it a crucial part of software management for both individuals and organizations.
