Patch

In the context of software and computer systems, a patch refers to a piece of code or software update that is applied to fix bugs, vulnerabilities, or enhance functionality in an existing software program or operating system. Patches are typically released by software vendors or developers to address issues discovered after the initial release of the software. Applying patches helps to improve security, stability, and performance of the software, and it is an important practice for maintaining a secure and up-to-date system.
