Q1Domain Verified
In the context of modern operating systems, which scheduling algorithm is most likely to be used for real-time systems requiring guaranteed response times and minimizing jitter, and why might it be preferred over preemptive priority-based scheduling in certain critical applications?
Round Robin
Earliest Deadline First (EDF)
Shortest Job Next (SJN)
First-Come, First-Served (FCFS)
Q2Domain Verified
Consider a multi-processor system employing symmetric multiprocessing (SMP). If a process is currently executing on CPU1 and requires access to a shared resource protected by a mutex, what is the most critical consideration for maintaining data integrity when another process on CPU2 attempts to acquire the same mutex?
The atomic nature of the mutex acquisition operation, preventing race conditions.
The operating system's kernel scheduler ensuring that CPU2 is not preempted while waiting for the mutex.
The memory management unit (MMU) ensuring that both CPUs have access to the same physical memory address for the mutex.
The cache coherence protocol ensuring that CPU2's cache line for the mutex is invalidated.
Q3Domain Verified
In the context of virtual memory management, what is the primary advantage of using a Translation Lookaside Buffer (TLB) in conjunction with page tables, and what potential performance bottleneck can arise if the TLB experiences a high miss rate?
The TLB speeds up virtual-to-physical address translation, but a high miss rate results in excessive context switching.
The TLB reduces the number of page table walks, but a high miss rate leads to increased I/O operations.
The TLB allows for larger page sizes, but a high miss rate causes significant fragmentation.
The TLB caches page table entries, but a high miss rate leads to increased memory latency due to repeated page table lookups.
