True or false
An interrupt can be triggered by hardware or by software instructions on the CPU. In modern operating systems, user processes generally run in kernel mode so that they can directly control the hardware. System programs provide a convenient environment for program development and execution. Linux does not distinguish between processes and threads and instead uses the term task to refer to flow of control within a program. The ready queue is a FIFO data structure that contains the set of all processes residing in main memory, ready and waiting to execute. Windows systems support both a message passing protocol and a shared memory protocol for IPC communications based on the size of the data being exchanged. In RR scheduling, the time quantum should be small with respect to the context-switch time. In the many-to-one multithreading model a single user thread is mapped to multiple kernel threads. The multilevel feedback-queue is the most general, yet most complex scheduling algorithm we discussed. A context-switch happens instantly in the operating system, with no overheadStep by Step Solution
