In the context of operating modes in a system, such as Kernel Mode and User Mode, service routines play a crucial role. In Kernel Mode, service routines have full access to system resources, allowing them to perform critical operations and manage hardware directly. On the other hand, in User Mode, service routines are restricted and can only access a limited set of resources, which helps protect the stability and security of the system. This separation between operating modes is essential to prevent malicious or faulty applications from affecting the overall functioning of the operating system.
