What is the difference between Server Components and Client Components in Next.js?

Server Components run on the server and send rendered HTML to the client, reducing JavaScript bundle size and improving performance. Client Components run in the browser and are required when using state management, event handlers, browser APIs, or React hooks such as useState and useEffect. Choosing the appropriate component type helps optimize application performance.
