Which of the following describes a dual-core processor?

A dual-core processor is designed to have two separate processing units (or cores) within a single physical processor. This design enables the processor to handle two tasks simultaneously, effectively allowing it to perform multiple operations at the same time. Each core can run its own thread, which significantly enhances performance during multitasking, as applications can spread their workloads across both cores.

Given that a dual-core processor focuses on completing tasks more efficiently by utilizing its two cores, it stands out as a significant advancement over single-core processors. This configuration is particularly beneficial in scenarios where multiple applications are open, enabling smoother performance and more efficient use of resources.

In contrast, other options describe characteristics that do not define dual-core processors. For instance, a processor that can only perform one task refers to single-core processors. Processors designed specifically for graphics processing relate to graphics processing units (GPUs), and those that require additional cooling could apply to various high-performance processors but are not unique to dual-core models. Therefore, the definition of a dual-core processor as one that can handle two tasks simultaneously is accurate and highlights its primary advantage in computing performance.
