Why are some system interfaces implemented by dedicated system calls (to the kernel), and others
on top of message-based system calls?
What will be an ideal response?
Dedicated system calls are more efficient for simple calls than message-based calls (in which a system action
is initiated by sending a message to the kernel, involving message construction, dispatch etc.).
However, the advantage of implementing a system call as an RPC is that then a process can perform operations
transparently on either remote or local resources.
