What is the difference between "bind" and "link"? [closed]

Bind and link are both verb and noun but the difference in meaning between these words are quite hard for me to catch.

I'd say the "the moral bind of the law" to express that both of them are tied tightly together. On the other hand, link would express more an relationship if I see it correctly.

But, when I say that "the system A (computer) is linked/bound with another system B", which of the two, link or bind, expresses that data flow from one system to another?

Solution 1:

Both link and bind can be used to express two systems in which data flows from one to the other. The difference is the degree of the relationship.

If two systems share a certain amount of information but are essentially independent then I would choose 'linked'.

Facebook and LinkedIn are linked because LinkedIn offers users the opportunity to publish updates to Facebook from LinkedIn.

If two systems require that data between the two be synchronized or are tightly related such that one cannot operate effectively without the other I would choose 'bound'.

The Facebook Messenger App is bound to Facebook because Messenger uses Facebook's credentials and Friend list to function. users cannot use Messenger without being on Facebook.
