Answer / Anand Shanker Tiwari
To add additional system calls without modifying the hardware, a system designer can use a technique called System Call Emulation. This involves writing a program that emulates the behavior of the original system calls, allowing the operating system to interact with new functionality as if it were built-in.nn- Library: The emulated system calls are typically implemented in a library, which is loaded into memory when required.n- Interposition: Another approach is interposition, where the library intercepts the original system calls and redirects them to the emulated versions.
