w3wp versus mvsmon

Hi, I'm trying to figure out the difference between w3wp and msvsmon. Both seem to be remote debugging tools that run on the web server, and we can attach to them via Visual Studio to help in debugging live applications. Is this correct ? If so what are the differences between them ? many thanks.

From stackoverflow

• w3wp is the w3 (www) worker process. This is what runs the website. This will allow remote debugging of websites.

  msvsmon is the remote debugger monitor, this is what actually allows remote debugging for all applications.
