Dual core是什么意思

"Dual core" is a term used in computing to describe a central processing unit (CPU) that contains two independent cores, or processing units, in a single chip. This allows the CPU to perform two sets of instructions at the same time, which can significantly improve overall processing performance compared to single-core processors.

When a task is assigned to a dual-core CPU, the operating system can assign one part of the task to each core, allowing them to work in parallel. This parallel processing capability is particularly beneficial for multitasking, multimedia applications, and other demanding tasks that require a lot of processing power.

Dual-core technology was introduced in the early 2000s as a way to address the growing demand for more processing power without significantly increasing power consumption or heat generation. Since then, CPUs with more than two cores (quad-core, hexa-core, octa-core, etc.) have become common, offering even greater parallel processing capabilities.
