Fоr eаch оf the fоllowing stаtements regаrding system calls, mark true or false: 1. At some point, an invoked system call traps to kernel mode [1] 2. On a single CPU, single core system, when a system call is called from user space, the calling process continues running in parallel with the system call [2] 3. A system call can be initiated and completed in user mode (without trapping to kernel mode during its execution steps) [3] 4. When a system call is called from user space, the calling process’ state is updated and saved so that execution can be resumed later [4]
