Simple Explanation

A method of connecting devices in a line so that each device passes data to the next one.

Concise Technical Definition

A data communication topology where devices are connected in sequence, each forwarding the signal to the next.

Layman-Friendly Analogy

Like stringing Christmas lights—if one bulb connects to the next, they all light up in sequence.

Industry Usage Summary

Used in digital audio (e.g., AES50, Thunderbolt), MIDI setups, and display or lighting systems to simplify cabling.

Engineering Shortcut

Connect device output to the next device's input. Signal flows down the chain, usually from master to final node.

Full Technical Explanation

A daisy chain is a wiring scheme where multiple devices are connected in a linear sequence using a single data path. Each device typically has an input and an output, passing the signal along. This setup simplifies wiring and reduces cable runs but can risk signal integrity if the chain is too long or improperly terminated.
