Question
For the following questions, answer by TRUE or FALSE. You do not have to attach any explanation to your solutions for these questions (1) User application processes request services from the operating system using function calls TRUE FALSE] (2) Microkerne I architecture operating systems improve their robustness mainly because some services are implemented as modules. TRUE FALSE] (3) Semaphore operations (wait and signal) can be implemented at a processor that does not have atomic instruction for each as long as interrupt can be disabled by the operating system. TRUE FALSE] (4) In round-robin, FCFS, shortest job first, and shortest remaining time first short-term process scheduling algorithms, round-robin algorithm is not the only preemptive scheduling algorithm [TRUE FASLE] (5) Because of multitasking operating systems, single-core single-processor computer systems execute more than one process physically at a time TRUE FASLEExplanation / Answer
According to chegg guidelines i have to solve first four bits only.
1.
User application process request service from the operating system using function calls
True.
2.
Microkernel architecture operating systems improve their robustness mainly because some services are implemented as modules.
True.
3.
semaphore operations can be implemented at a processor that does not have atomic instruction for each as long as interrupt can be disabled by the operating system
False.
4.
in round - robin fcfs shortest job first and remaining time first short-term process scheduling algorithm, round-robin algorithm is not only preemptive scheduling algorithm.
True
