Which of the following best describes the relationship between computers and instruction execution?

The statement that computers can execute a large number of instructions quickly is accurate and reflects the fundamental capabilities of modern computers. This efficiency comes from the architecture of computers, which allows them to process millions or even billions of instructions per second.

The ability to execute a vast array of instructions arises from advancements in hardware, such as multi-core processors and optimized instruction sets, which enable concurrent operations and rapid processing. This capacity is crucial for handling complex applications, performing calculations, and processing data in real-time, supporting everything from basic tasks to high-performance computing.

While it is true that computers can only execute a specific set of instructions defined by their architecture, the emphasis here is on the speed and volume of instruction execution, making this choice the most fitting.
