KDE Platform 4 was a collection of libraries and software frameworks by KDE that served as technological foundation for KDE Software Compilation 4 distributed under the GNU Lesser General Public License (LGPL).

KParts is the component framework for the KDE Plasma desktop environment.

Konsole is available as a KPart and is used in applications like Konqueror and Kate.

It functions on similar principles to KDE's multimedia pillar Phonon; rather than managing hardware on its own, it makes existing solutions accessible through a single API.

The current solution uses udev, NetworkManager and BlueZ (the official Linux Bluetooth stack).
