Are Apache and MySQL multithreaded applications?

Solution

It depends on how to look at it.

MySQL allows you to run multiple threads at the same time (this comes to available CPU/RAM resources), but it won't allow you to run a single query using multiple threads.

Apache is multithreaded, this is the only way how the web application server could respond to multiple requests from different clients.

Problem

I was wondering if the default installations of Apache and MySQL on Windows/Linux are multithreaded or not?
