KDED stands for KDE Daemon which isn't very descriptive. KDED runs in the background and performs a number of small tasks. Some of these tasks are built in, others are started on demand.

### Built in tasks

* Checking for newly installed software and updating ksycoca when new software is detected. Updating of ksycoca is done by the program kbuildsycoca which gets started by kded. When kded is first started it always runs kbuildsycoca to ensure that ksycoca is up to date.

* Checking for newly installed update files. Applications can install *.upd update files. These *.upd files are used to update configuration files of users, primarily when new versions of applications are installed with (slightly) different configuration file formats. Updating of configuration files is done by kconf_update. kded starts kconf_update when it detects a new update file. When kded is first started it always runs kconf_update to ensure that it has not missed any update files. kconf_update keeps track of which update files have been processed already in the config-file kconf_updaterc. It only performs a certain update once.
