Such feats are known as emulation. A certain set of data is required (the game) and a program to run the information is needed as well (emulator). Currently the best emulator is cxbx. The homepage is here: http://www.caustik.com/cxbx/
If you read the whole website and some forums you might have learned only a few games can be played. Since Xbox 360 came out, there is little need to continue work on it, but it is open source so those who care can add to it.
Getting games is another story. You must hack your xbox and use an ftp client to download games and necessary files from the disk. Or you could do it illegally, but you can find out how do that on Google since I strongly recommend you don't do that. The size of games though are huge on the hard drive.
So as you can see, the xbox emulation for the computer has brought up many problems. Continuation of it is very unlikely. So I'd say abandon hope.
Good luck with other emulations though!

No you can not play xbox on line with PC.
No you can not play xbox on line with PC.
No you can not play xbox on line with PC.
No. There is no way to play PC games on a Xbox.
No, the xbox 360 cannot play games that were developed for pc, and vice versa.
Yes, but you cannot play from one with a friend on another. Communications are fine, but you can't play between PC and Xbox, only PC to PC or Xbox to Xbox
you can play only some games on pc and to do so you will need a emulator you can find it on google although in my opinion xbox games should always be played on xbox otherwise its useless to buy a xbox if you play all its game on a freaking pc ,its an other thing you if just buy a xbox game so that you can play it on pc
No you can only play mw3 on xbox 360 (and pc and ps3 of course) not on xbox.
Well no, but you might run it on a PC screen,and the old xbox,ps2 has "Emulators" you can download to your PC and then play they're games on the PC! Soon the Xbox 360 Emulator will be out(i think) But i recommned a gamer PC, if you want to run them:P
you cannot physically insert PC games into the xbox 360 and play them. but most PC games are made for the Xbox too, (same company, go figure...) so u have to buy a second copy for the xbox if u want to play it there.
no
you don't
