Hyperlinks are a crucial way to share data online. Links allow people to quickly jump to another location or file on the internet by clicking. You can add links to emails, documents, messages, and web pages (HTML documents).
LINK meaning: 1 : to join or connect (two or more things, places, etc.) together; 2 : to connect (someone or something) to a system, network, etc.
With communications, a link is a connection between two devices. For example, when you connect to the Internet, your computer establishes a link to a modem or router.
