Quick Answer
GET sends data in the URL query string - visible, bookmarkable, cached, length-limited. Use for read-only operations like search. POST sends data in the request body - not visible in URL, supports large payloads and file uploads. Use for write operations like form submission or login. Both need validation before use.
Answer
GET appends data to the URL and is limited in size. POST sends data in the request body, supports larger payloads, and is more secure for sensitive data.
