Which CPU scheduling algorithm is best for an interactive time-sharing OS to ensure quick response time?
💡 Explanation:Round Robin (RR) is a preemptive scheduling algorithm specifically designed for time-sharing systems. It assigns a fixed time slice (quantum) to each process, ensuring that every process receives a fair share of the CPU at regular intervals. This preemption and fair distribution minimize the average response time for interactive users, preventing any single process from monopolizing the CPU.

When downloading a large file, which protocol primarily ensures that data packets arrive in the correct sequence and are acknowledged?
💡 Explanation:Transmission Control Protocol (TCP) is a core transport layer protocol responsible for reliable, ordered, and error-checked delivery of data streams. It establishes a connection, segments data, retransmits lost packets, and ensures data arrives in the correct sequence (acknowledged). User Datagram Protocol (UDP) is also transport layer but is connectionless and unreliable, prioritizing speed over guaranteed delivery. IP handles addressing and routing, while HTTP is an application layer protocol that typically uses TCP.

Which function fundamentally distinguishes TCP from UDP in network communication?
💡 Explanation:Transmission Control Protocol (TCP) is a connection-oriented protocol that ensures the reliable, sequential, and guaranteed delivery of data packets through mechanisms like sequencing and acknowledgments. User Datagram Protocol (UDP) is a connectionless protocol that offers faster, lower-overhead transmission but provides no guarantees of delivery or packet order. Thus, guaranteed delivery and ordered packets is the key distinguishing function.

What is the smallest addressable unit of memory in most modern computer architectures?
💡 Explanation:A byte (typically 8 bits) is the smallest addressable unit of memory in virtually all modern computer systems. While a bit is the fundamental unit of data (0 or 1), it cannot be individually accessed or addressed by a memory pointer.

What is the primary implication if P=NP is proven true in complexity theory?
💡 Explanation:P (Polynomial time) is the class of problems that can be *solved* quickly (in polynomial time). NP (Non-deterministic Polynomial time) is the class of problems for which a proposed solution can be *verified* quickly. If P=NP, it implies that every problem whose solution can be quickly verified (NP) also has an efficient, deterministic algorithm to find that solution quickly (P). This would revolutionize fields like cryptography and optimization.

What is the primary function of the kernel in a computer’s Operating System?
💡 Explanation:The kernel is the core component of an Operating System, primarily responsible for managing system resources such as the CPU, memory, and input/output (I/O) devices, and for mediating communication between hardware and software components.

Requiring a process to request all needed resources simultaneously prevents which classic deadlock condition?
💡 Explanation:Deadlock is possible when four necessary conditions hold: Mutual Exclusion, Hold and Wait, No Preemption, and Circular Wait. The strategy of requiring a process to request all its resources at the beginning and only allowing it to proceed if all are available directly prevents the 'Hold and Wait' condition. If a process is holding resources, it is guaranteed not to be simultaneously waiting for additional ones, as all have already been granted.

What does Big O notation primarily measure in computer science?
💡 Explanation:Big O notation describes the performance or complexity of an algorithm, specifically how its run time or space requirements grow as input size increases.
