How the MMU (memory management unit) in the processor protects memory segments

Having gone through one embedded processor architecture, I saw the MMU and mostly mentions memory protection features.

May i know

How does the MMU implement this protection and why is it needed? What does memory protection mean?

What are other ways to use MMU besides security (for example, virtual addressing)?

Pay attention to the embedded system without an OS.

There are many, many other functions provided by the MMU (virtual memory, dynamic movement, etc.).
