The CPU, or Central Processing Unit, is often referred to as the brain of a computer. It performs the essential tasks of processing instructions, managing data, and executing commands from software applications. The speed and efficiency of a CPU significantly impact the overall performance of a computer system. Modern CPUs are designed with multiple cores, allowing them to handle several tasks simultaneously. This multi-core architecture enhances multitasking capabilities and improves performance in demanding applications such as gaming and video editing. As technology advances, CPUs continue to evolve, becoming faster and more efficient to meet the needs of users.
