   - Is a microcontroller (MC) a central processing unit (CPU)?
+  - What does SoC mean?
   - What is a processor core?
   - How may cores does a microcontroller have? Compare EPS32-S2 and ESP32-C3.
+  - Ask perplexity.ai: \\ (1) Where do I find the original datasheet of ESP32-S3? \\ (2) Where do I find the original datasheet of ATmega328 (the MC of the original Arduino UNO board)? \\ Search for the functional block diagrams in both datasheets (rather thick manuals) and compare them. Can you identify functional blocks they have in common?

   - Are tasks in a super loop executed sequentially or concurrently?
   - How many threads can be run on a single CPU core in parallel, i.e. at the same time?
-  - Tasks on RTOS are executed concurrently. Are they also executed in parallel? Is real parallel execution possible in MCs?
+  - Tasks on RTOS are executed concurrently. Are they also executed in parallel? Is real parallel execution, i.e. tasks are executed at the same time, possible in MCs?
   - What does task priority mean?
   - Can the standard MC interrupt request (IRQ) mechanism still be used together with RTOS to react extremely fast to events like timer events, external sensor readings, or user interactions?
+  - RTOS is never faster and more responsive than a super loop with interrupts. Why would you use RTOS?
