Answer
Synchronous: Blocks the calling thread until the operation completes.
Asynchronous: Continues execution without blocking, offering better scalability and responsiveness.
Quick Answer
Synchronous code runs step by step, blocking the thread until each operation finishes — simple but wasteful for I/O. Async with await frees the thread while waiting and resumes later. On a web server, async lets one thread handle many concurrent requests instead of sitting idle waiting for DB responses.
