Request-Response

Definitions

1. A communication pattern in which a client sends a single request and synchronously waits for a single response from the server, forming a paired exchange. HTTP is the canonical request-response protocol, in contrast to streaming, event-driven, or fire-and-forget models.

   In plain English: The basic back-and-forth pattern where you ask a server for something and wait for it to send back an answer.

   Example: "REST is inherently request-response, which makes long-polling awkward — for real-time updates we switched to WebSockets."
