+- **KDE Plasma:** A highly customizable and visually appealing desktop environment for Linux and other Unix-like systems. It includes panels, widgets, system settings, and window management.
+- **KDE Frameworks:** Modular libraries that support KDE applications and can be used independently by other software projects.
+- **KDE Gear:** A collection of KDE applications released together, including tools like:
+  - Krita (digital painting)
+  - Kate (text editor)
+  - Kdenlive (video editor)
+  - digiKam (photo management)
+  - Konsole (terminal emulator)
+- **Display Manager:** [SSDM](../display-managers/sddm.md)
