Multi-core processing refers to the use of multiple processing units, or cores, within a single computer chip. Each core can independently execute tasks, allowing for better performance and efficiency. This technology enables computers to handle multiple applications or processes simultaneously, improving overall speed and responsiveness. By distributing workloads across different cores, multi-core processors can significantly enhance computing power without increasing the clock speed. This is particularly beneficial for tasks that require heavy computation, such as video editing or gaming, where programs can utilize the capabilities of each core to perform complex calculations more quickly.
