Which cloud service model offers fundamental computing, storage, and networking resources on-demand?

Answer

Infrastructure as a Service (IaaS) is the cloud model that provides the fundamental, virtualized computing resources—servers (compute), storage, and networks—over the internet on an on-demand, pay-as-you-go basis. It gives the user the highest level of control over their operating systems and applications, while the cloud provider manages the physical hardware.

What is the defining characteristic of Artificial General Intelligence (AGI)?

Answer

Artificial General Intelligence (AGI), also known as Strong AI, is defined by its ability to successfully perform any intellectual task that a human being can, including learning, reasoning, and applying knowledge across diverse domains. This contrasts with Narrow AI (Weak AI), which is only capable of performing a specific, specialized task.

Which CPU scheduling algorithm is best for an interactive time-sharing OS to ensure quick response time?

Answer

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.

What fundamental capability distinguishes a quantum bit (qubit) from a classical bit?

Answer

A classical bit can only be in one state (0 or 1) at any given time. A quantum bit, or qubit, can leverage the quantum mechanical principle of superposition to exist as a weighted combination of 0 and 1 simultaneously until it is measured. This capability allows quantum computers to perform computations on multiple states concurrently, leading to potential exponential speedups for certain problems.

When downloading a large file, which protocol primarily ensures that data packets arrive in the correct sequence and are acknowledged?

Answer

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.

A movie recommendation system based on user history utilizes which core AI technique?

Answer

Recommendation systems analyze patterns in user data (such as viewing history, ratings, and past purchases) to predict future preferences and suggest content. This process of learning from data to make predictions without being explicitly programmed is the definition and core function of Machine Learning (ML).

Which cloud service model provides fully managed software accessible via a web browser?

Answer

Software as a Service (SaaS) is a cloud computing model that provides end-user applications over the internet, with the provider managing the entire infrastructure, operating system, and software maintenance.

What is the foundational suite of protocols used for communication across the Internet?

Answer

The Transmission Control Protocol/Internet Protocol (TCP/IP) is the foundational set of communication protocols used to interconnect network devices on the Internet. It defines how data should be packaged, addressed (IP), transmitted, and received (TCP).

Which function fundamentally distinguishes TCP from UDP in network communication?

Answer

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.
