What does a patch typically address?

A patch is specifically designed to address a particular problem or vulnerability within software or an operating system. This can include fixing bugs, closing security gaps, or providing enhancements to functionality without a need for a complete software overhaul.

When issues are identified in software performance, stability, or security, developers often create patches to resolve these specific issues efficiently, allowing users to continue operating with minimal disruption. This targeted approach is essential in maintaining the integrity and security of software systems, especially in environments where stability and safety are critical, such as in industrial control systems.

Other potential choices do not accurately represent the primary function of a patch. For instance, hardware failures require physical repairs or replacements, and compatibility issues typically necessitate more extensive solutions or updates beyond a patch. Complete overhauls involve significant redesign and redevelopment of the software, which is beyond the scope of what a patch is meant to accomplish. Hence, a patch directly serves to resolve specific issues within existing software rather than undertaking larger modifications or repairs.
