Why does Pycharm open ports at the Python Console / IPython and how can I turn this off?

I have now dealt a little more intensively with the open ports.

They also appear in the Community version and not only in the Pro. And that's exactly when you open a 'Python Console', whether 'IPython' or 'Standard console'.

It will be displayed when the terminal starts:
/pycharm-community/helpers/pydev/pydevconsole.py 33005 33135

1. Why is that the case? [please detailed answer]
2. How can I switch off this behavior?

I find it scary that PyCharm opens a port for each 'Python Console'. My Linux has no open ports and I do not want to have any unnecessary open ports.
