Dual-core (2 Core)

A dual-core processor is a CPU with two independent cores on one chip. Each runs instructions concurrently, resulting in parallel processing and better multi-tasking than single-string processors. The processor fetches instructions from memory and sends the outcomes to one of two cores. The cores operate while executing different instructions at once. This parallel processing ability increases general system efficiency and accelerates the completion of tasks.

Several factors contribute to the efficiency of a dual-core processor, such as clock speed, cache size, and microarchitecture. Fast clock speeds allow the execution of instructions at a  pace. Large caches temporarily store data that is frequently accessed. Good microarchitecture design efficiently uses resources, and the cores can process instructions well.
