Sure! React Server Components (RSC) let you render components on the server. They can directly access backend resources like databases and file systems without an API layer. The key difference from traditional SSR is that RSC never ship their JavaScript to the client — they render once on the server and send HTML.

Client Components are the traditional React components you're used to. They run in the browser, can use hooks like useState and useEffect, and handle interactivity. You mark them with "use client" at the top. Server Components are the default in Next.js App Router — they can't use browser APIs or hooks, but they reduce the JavaScript bundle sent to the client.

Absolutely! That's the whole idea. You can import Client Components into Server Components. The Server Component handles data fetching and layout, while Client Components handle interactive parts. Think of it as a tree where Server Components are the branches and Client Components are the interactive leaves.

In Server Components, you can use async/await directly — just make the component async and fetch data at the top level. No need for useEffect or state management for server data. For Client Components, you can pass data as props from a parent Server Component, or use traditional patterns like SWR or React Query for client-side fetching.

Next.js extends fetch with automatic caching and revalidation. You can set cache behavior per-request with options like { cache: "force-cache" } or { next: { revalidate: 60 } }. There's also the unstable_cache API for caching non-fetch operations like database queries. The App Router also has built-in route segment caching.
