Patch

A patch is a set of changes to a computer program or its supporting data designed to update, fix, or improve it. These changes are typically small, incremental modifications applied to existing software to address bugs, correct security vulnerabilities, enhance performance, or add minor features. Patches are a critical component of software maintenance and security, ensuring that applications remain stable, secure, and performant over their lifecycle. They are often distributed electronically and applied by users or system administrators.
