What is the primary role of shimming in system processes?

Shimming primarily involves redirecting system calls between processes to modify or enhance the functionality of those calls without altering the original code. This technique allows developers to address compatibility issues or to provide additional features by inserting a layer that intercepts requests from a calling program to the operating system or other APIs. By doing so, shimming can create a seamless experience for users, ensuring that applications work as intended even when the underlying system changes.

Shimming does not inherently enhance system security, store data temporarily, or increase processing speed, which distinguishes it as a technique focused on interaction and compatibility rather than these other functionalities.
