What is it really in plain English?

Answer 1

WSGI runs the Python interpreter on web server start, either as part of the web server process (embedded mode) or as a separate process (daemon mode), and loads the script into it. Each request results in a specific function in the script being called, with the request environment passed as arguments to the function.

CGI runs the script as a separate process each request and uses environment variables, stdin, and stdout to "communicate" with it.
