For & UNIX; operating systems there are often different users, which in turn might have different privileges. The conventional method is to have an ordinary user account, whose files are generally stored in / home/ username, and then to also have a root account. The root, or Super User, account has system-wide privileges, being able to modify any file on the system.
Non sistemas operativos & UNIX; polo xeral hai diferentes usuarios, que poden ter diferentes privilexios. O normal é ter unha conta de usuario normal, que ten os ficheiros en / home/ usuario, e ter á parte unha conta root. A conta root, ou superusuario, ten privilexios sobre todo o sistema, polo que pode modificar calquera ficheiro no sistema.
