Review Operating system basics before starting →Ideas to recall
- The operating system acts as an intermediary resource manager and hardware abstraction layer for software.
- The kernel executes in privileged kernel mode; applications execute in unprivileged user mode using system calls.
- Preemptive process scheduling guarantees fair CPU time distribution and responsive multitasking.
- Virtual memory provides each process with an isolated, contiguous address space backed by physical RAM and swap space.
Use these ideas to reason through each question; answer-specific explanations appear only after you check a response.
