Layman's Definition: Using the analogy of a restaurant, a central processor unit (CPU) would play the role of a chef or a team comprised of a chef and his head cooks. Most modern CPUs have multiple cores which work together to get tasks done faster just as a chef and his head cooks prepare food together to get it to the table in a timely manner. In rare cases a computer contains multiple CPUs which would be similar to having a team of chefs.
