A socket is a hollow, recessed component designed to receive, hold, or connect another part, commonly used in electrical, mechanical, and computing contexts. It enables safe power transfer (wall socket), provides a secure interface for tools (socket wrench), or establishes network communication (network socket).

A relay is an electrically operated switch that uses a low-power signal to control a higher-power circuit, providing electrical isolation. Primarily used in automation, automotive systems, and appliances, they turn devices on/off, such as TV power via remote or managing motor loads. Synonyms include switch, transmitter, or repeater.
