Re: immutable tags?

I would like to know if there is any difference between branches and
tags. Is it only conceptual - convention to be followed by a developer
or some technical difference?  e.g. : Is it possible to create
immutable tags so that nothing can be checked in to that 'tagged
directory'?

A tag is just a named reference to a particular commit (or other
object indeed). Once you set a tag, it doesn't move (unless you
override it explicitely).

You can't prevent people from commiting something. It won't move the
tag, but it will create a new commit whose parent is the tagged
commit.

A branch is also a named reference to a commit, but the difference is
that when you commit, the current branch is updated (i.e. the
reference points to the new commit).
