Permissions

Sorry for my basic question.
If I want to give permissions to read write or full controll etc... I just need to use the security tab from the properties of a resource and tick on allow. If I want to block the permission for an object ex: user or group I can use deny ....but removing the object from the list [group or users name] seems has the same effect >> no permission<<. Actually....what is the difference between the two actions?
Many Thanks

For this reason, it is usually preferable not to deny objects rights, but rather to only grant rights to those objects which should have them.
