  <title>Como funcionan os privilexios administrativos?</title>

  <p>Así como os ficheiros que <em>vostede</em> crea, o seu computador tamén ten un número de ficheiros necesarios para que o sistema funcione correctamente. Se ditos <em>ficheiros do sistema</em> importantes cambian de forma non axeitada pode facer que algo se estrague, polo que están protexidos dos cambios por omisión. Certas aplicacións tamén modifican partes importantes do sistema polo que tamén están protexidos.</p>

  <p>A forma na que están protexidos é permitindo só aos usuarios con <em>privilexios administrativos</em> cambiar os ficheiros ou usar as aplicacións. No uso diario non necesistará cambiar ningún ficheiro do sistema ou usar estas aplicacións así que de maneira predeterminada non terá privilexios administrativos.</p>

  <p>A veces é preciso empregar estas aplicacións, polo que pode obter temporalmente privilexios de administrador para poder realizar os cambios. Se unha aplicación precisa de privilexios de administrador, pediráselle o seu contrasinal. Por exemplo, se desexa instalar un novo software, o instalador de software (xestor de paquetes) pediralle o seu contrasinal de administrador para que poida engadir o nova aplicación ao sistema. Unha vez teña rematado, os seus privilexios de administrarán quitaránselle de novo.</p>

  <p>Administrative privileges are associated with your user account.
  <gui>Administrator</gui> users are allowed to have these privileges while
  <gui>Standard</gui> users are not. Without administrative privileges you will
  not be able to install software. Some user accounts (for example, the “root”
  account) have permanent administrative privileges. You should not use
  administrative privileges all of the time, because you might accidentally
  change something you did not intend to (like delete a needed system file, for
  example).</p>

  <p>In summary, administrative privileges allow you to change important parts
  of your system when needed, but prevent you from doing it accidentally.</p>

  <note>
    <title>What does “superuser” mean?</title>
    <p>A user with administrative privileges is sometimes called a
    <em>superuser</em>. This is simply because that user has more privileges
    than normal users. You might see people discussing things like <cmd>su</cmd>
    and <cmd>sudo</cmd>; these are programs for temporarily giving you
    “superuser” (administrative) privileges.</p>

<section id="advantages">
  <title>Por que son os privilexios de administración útiles?</title>

  <p>Requiring users to have administrative privileges before important system
  changes are made is useful because it helps to prevent your system from being
  broken, intentionally or unintentionally.</p>

  <p>If you had administrative privileges all of the time, you might
  accidentally change an important file, or run an application which changes
  something important by mistake. Only getting administrative privileges
  temporarily, when you need them, reduces the risk of these mistakes
  happening.</p>

  <p>Only certain trusted users should be allowed to have administrative
  privileges. This prevents other users from messing with the computer and
  doing things like uninstalling applications that you need, installing
  applications that you don’t want, or changing important files. This is useful
  from a security standpoint.</p>
