In the context of computers, the term ''shim'' refers to a piece of software or code that acts as an intermediary layer between two software components or systems. Shims are used to bridge compatibility gaps, provide backward compatibility, or enhance interoperability between different software modules or versions.

"A compatibility shim in operating systems, like ''Windows XP SP2 Compatibility Mode,'' emulates older system behaviors to ensure legacy applications function correctly on newer OS versions, avoiding compatibility issues."
