What does "multi-core" refer to in processors?

1. A single processor chip with enhanced graphics

2. Multiple processors working independently

3. Placing two processors on a single processor chip or die

4. Processors designed for mobile devices

The correct answer is: Placing two processors on a single processor chip or die

"Multi-core" refers to placing two or more processor cores on a single processor chip or die. This design allows for the execution of multiple processes or threads simultaneously, enhancing the overall performance and efficiency of the computing device. Each core can independently process data, which increases the system's ability to multitask and improves performance for applications designed to take advantage of multiple cores. The benefits of multi-core processors include improved computational speed for demanding applications, better performance in multi-threaded tasks, and overall energy efficiency, as multiple cores can share the workload effectively without the need for multiple discrete processors, thereby reducing heat output and power consumption. The other options do not accurately define "multi-core." For instance, a single processor with enhanced graphics does not necessarily involve multiple cores. Similarly, having multiple processors working independently refers more to multi-processor systems rather than multi-core, and processors designed for mobile devices do not inherently mean that they are multi-core—the term encompasses a broader range of configurations.
