‘链路’ (liàn lù) is a technical noun used primarily in computer networking and telecommunications. It refers to a communication path or connection between two points—such as between two devices, nodes, or network segments—over which data can be transmitted. The character ‘链’ (liàn) means ‘chain’, suggesting a connected sequence, while ‘路’ (lù) means ‘path’ or ‘route’, emphasizing the channel or conduit for transmission. Together, they convey the idea of a dedicated, end-to-end communication ‘chain-path’.

This term is common in technical documentation, network design discussions, and IT support contexts. Unlike general terms like ‘connection’ or ‘link’, 链路 specifically implies a functional, bidirectional data pathway with defined endpoints and often measurable properties (e.g., bandwidth, latency). It is rarely used outside engineering or IT domains and does not appear in everyday conversation or non-technical writing.
