How is a service desk different from a help desk?

A service desk is a broader IT support function that not only addresses user issues but also manages service requests, incidents, and changes, facilitating communication between IT and the business. In contrast, a help desk primarily focuses on resolving technical problems and providing immediate support for users' issues. While both aim to enhance user experience, the service desk takes a more comprehensive approach, encompassing service management processes and aligning IT services with business goals.
