Link is an English word, but it is already widely used in Japanese as a word that means to connect.
As a verb, it means to connect or combine two things, and as a noun, it means a link in a chain, a ring, or a bond.

A link is a line or path that connects the elements that make up a structure or network made up of multiple connected elements.
hyperlink

Content documents such as websites may contain words or sentences that you can click to go to the source of information or other related sites.
Words and sentences are generally highlighted and underbard, and these words and sentences are called hyperlinks.
The location of a link destination is expressed using a fixed notation (URL/URI), and it is possible to move to other websites as well as content within the same website (internal links).

communication network link
A communication network consists of individual computers and communication devices connected together, and the lines and transmission paths that connect the individual computers and communication devices so that they can send and receive are called links.
A connection state in which computers and communication devices can send and receive signals is a state in which signals can be sent and received, and large units of data can be sent and received. Securing this connection state is called establishing a link.

file system link

In a computer’s file system, a link is a link that allows a file to be referenced from a different location on the computer than where it is stored.
There are two types of file system links: hard links and soft links.

A hard link is a link that has multiple names, such as a file, so that it functions like a file.
On the other hand, a soft link is a function that creates a special file that specifies a file, allowing you to view or create the file from a location other than the file storage location.
Soft links are shortcuts in Windows and aliases in macOS.

Development/programming links
In software development and programming, linking is the process of combining multiple files containing programs to create an executable file.
Software development and programming links are automatically performed using special software called a linker.
