"noun: (computing) an instruction that connects one part of a program or an element on a list to another program or list"

Hmm. Not sure, as is FF, what is being referred to in this definition. There is a phase in writing programs called linking. It comes after compilation of source code into binary object files whereby two or more binary object files are concatenated together into one single executable file. Another meaning of link, besides the HTML-oriented (hyper)link is a symbolic link. In the context of Unix-like file systems a symbolic link is similar to a Windows file shortcut. It is a kind of alias of a file. In the context of data structures, specifically a linked list, a link could be a synonym for a pointer (as was earlier mentioned).

Ceci n'est pas un seing.
