link

Link is a word with several meanings centered on connection. In general usage, a link is a connection from one thing to another, a bridge that allows transfer of information, materials, or influence.

In computing and on the Web, a link typically refers to a hyperlink: a reference embedded in text or an image that users can activate to open another resource, usually a web address (URL). Hyperlinks enable navigation across documents, sites, or files. They can be external or internal and are implemented with markup languages such as HTML.

In data structures and networking, a link denotes a reference or pointer from one node to another. In a linked list, each element holds a link to the next. In graph theory, edges are links between vertices. In networks, links can represent communication channels or data connections.

In the physical world, a link is a single ring or loop that forms part of a chain, rope, or fence. Chains and chain fences derive their strength from the individual links.

Culturally, Link is the name of the fictional hero of Nintendo's The Legend of Zelda series, introduced in 1986. The character is typically portrayed as a courageous adventurer who collects artifacts, solves puzzles, and defeats villains. The name is often treated as a given name rather than a surname in fan usage.

As a proper noun, Link also appears as a surname and as a given name; notable people include Link Wray, an American musician known for early rock instrumentals.
