It is a special user (also known as the "superuser") who is not constrained by the system permissions; they may open any file et, and also perform various other privileged operations (become another user, shut the system down, etc). | I thought a root is top level of the directory . The same word, used for a different purpose. | Also I hear in Unix ,Linux and Mac the user cannot modify, install, or remove anything with out password. Not true. Users may install stuff anywhere they have permission to do so. _Normally_, a user has permission to work in the own home directory. Within there they can thus install software, write data files etc. _Outside_ their home directory, they will normally not have rights to modify things. So, doing a "system wide" install, such as software that other users will use because it it in the "standard" places generally needs to be done by the "root" user. Many systems provide an interface that _runs_ as root, and asks the user for a password before proceeding to do the install _for_ them. That will be what you have heard of.
