<title>D-Bus</title>

<p>D-Bus is a message bus for sending messages between
various applications, the desktop, and low-level components of the system.
D-Bus provides a simple API for sending messages to particular services
and for broadcasting messages to all interested services.  D-Bus enables
different types of applications to communicate and integrate with each
other and with the desktop, providing better interaction and a richer
experience for the user.  </p>

<p>D-Bus provides a session bus and a system bus.  The session bus is
used by applications in a single user session, allowing them to share
data and event notifications and to integrate into the user's desktop.
For example, movie players can send a D-Bus message to prevent the
screensaver from activating while the user is watching a movie.</p>

<p>O bus do sistema é un bus dun só mensaxe que se executa independentemente de calquera sesión de usuario. Pódese comunicar cos aplicativos de calquera sesión, permitindo a ditos aplicativos interactuar cos compoñentes do sistema sen ter que tratar con detalles de baixo nivel do sistema. O bus do sistema úsase para fornecer unha funcionalidade importante que os usuarios agardan que funcione nos seus sistemas. Por exemplo, o bus do sistema úsase para monitorizar cando as interfaces de rede se conectan ou desconectan, cando se conectan unidades externas e cando a batería do sistema está baixa.</p>

<p>D-Bus é desenvolvido conxuntamente en <link href="http://www.freedesktop.org/">freedesktop.org</link>, de tal forma que pode usalo con diferentes contornos de escritorio e aplicativos. Debido a que D-Bus é un proxecto multiescritorio, pode usalo para crear software portábel e versátil que se integre dun modo transparente co escritorio do usuario, independente de que escritorio sexa.</p>

  <p>GNOME provides full support for D-Bus using the GDBus APIs in
