Link, in computing, is the term used to describe the connection of two or more computing devices that exchange information over a particular channel. This channel can be either a physical connection like a cable or a wireless connection. In networking, a link is used to connect two or more nodes in order to create a network. It can also be used to refer to a path in a network topology or data structure which guides the flow of data from one node to another.
Links are commonly used for sharing, transferring and downloading files. In addition, it can also be an integral part of networking protocols such as Ethernet, in which the nodes communicate by sending and receiving data over the link. A link, in this case, is the means of physical or logical connection between two nodes or devices on a network.
Furthermore, a link also refers to a hyperlink, a type of link found in hypertext documents. Hyperlinks are commonly known as the way to link from one page to another. Hyperlinks can also be used to link from an external webpage to a specific section or part of an internal web page.
In software engineering, a link is also referred to as a connection between libraries, functions or object programs. Object codes or executable files sometimes include links to the target library or executable or DLLs. In this context, a link is also called a binding or an import.
Links are a fundamental aspect of networking and data transmission, and play an important role in the Internet and other digital networks. They are used in various contexts such as distributed applications, cloud computing, streaming data and much more.
