Relay (computer science)

In computer science, a relay refers to a component or system that receives input signals, processes or directs them, and then passes them on to another part of a network or system. Think of it like a relay race baton handoff, where each runner (or component) hands the baton (the data or signal) to the next. Relays are used in networking to route messages efficiently, or in hardware to control circuits remotely. They help manage and coordinate data flow, ensuring information reaches the right destination at the right time.
