3 Questions.

1. Whenever I look at (nearly any) OS, it offers a 64 and a 32 bit OS version.

What is the difference between them? Is 64-bit more powerful?

If that's the case, whats the point of offering a 32-bit version?

2. If I run Persistence mode on Kali via my USB, and download a tool, next time I plug it into a computer and run the normal 648pae mode, will the tool still be there?

3. How can I use Python to create a script that interacts with ActivityMonitor (OSX) or TaskManager (Windows)?

I want to make a script/tool that detects possible malicious programs/processes running on a computer.

Github code is HERE

Am I doing this right?

thanks
