Difference between hardlink and bind mount?

this might be a silly question, but:

bind mounts under linux:

as far as i understand: you can install the same directory in two different locations.

but where is the difference with hard links?

The binding is mounted. Starting with Linux 2.4.0, it is possible to redo part of the file hierarchy elsewhere. Call:

mount -bind olddir newdir

Is this just another way to make the folder available? (but it doesn't actually use any network protocol because it is local)

please give some examples for / against.

thank:)
