What type of software is an update or improvement to an existing program?

The term that describes an update or improvement to an existing software program is referred to as a patch. Patches are released by software developers to fix bugs, enhance functionality, or address security vulnerabilities. They allow the original program to improve its performance or reliability without requiring the end user to obtain a completely new version of the software. By applying a patch, users can ensure that they are using the most secure and efficient version of the software available.

In the context of software asset management, keeping track of these patches is crucial, as it can impact compliance, security, and overall software performance. Organizations are often required to maintain up-to-date software to protect against potential risks that arise from unpatched vulnerabilities.
