Answer 1

Both CGI and WSGI define standard interfaces that programs can use to handle web requests. The CGI interface is at a lower level than WSGI, and involves the server setting up environment variables containing the data from the HTTP request, with the program returning something formatted pretty much like a bare HTTP server response.

WSGI, on the other hand, is a Python-specific, slightly higher-level interface that allows programmers to write applications that are server-agnostic and which can be wrapped in other WSGI applications (middleware).
