+
+# Was ist eine CPU?
+
+- Herzstück eines Computers
+- Kleiner Chip auf Hauptplatine
+- Verarbeitung Arithmetik und Logik
+- Zugriff auf Speicher und Peripherie
+
+![bg right](./assets/harrison-broadbent-VOz0gV9HC0I-unsplash.jpg)
+
+---
+
+## Aufbau
+
+![bg right:35% fit](./assets/was-ist-cpu-darstellung.png)
+
+- _Steuerwerk, Rechenwerk, Cache, Register_
+- Cache: schneller Speicher für oft benötigte Daten
+- CPU kommuniziert über Bus-Systeme
+- Leistung abhängig von Kernzahl, Taktfrequenz, Cache und Architektur
+- Neueste Entwicklungen: Multi-Core-Prozessoren und KI
+
+---
+
+## Machine code
+
+- Niedrigste Ebene der Programmierung.
+- Binäre Instruktionen, direkt von der CPU ausgeführt
+- Jede CPU-Architektur hat ihre eigene Maschinensprache, die spezifisch für diese Architektur ist
+
+- Sehr effizient, da direkt von CPU ausgeführt
+- Meist in höherer Programmiersprache geschrieben
+
