You can't use a playstation controller on a computer.
connect your ps4 to your pc or monitor
You can't join a playstation to a PC.
I'm not sure what you mean by hook. The PS3 uses it's own internet connection with an ability to connect to the internet using WiFi or an ethernet cable only and needs a TV or HDTV for Audio and Video not a computer monitor. You certainly can not run your PS3 using the computer as a controller or otherwise play PS3 games with your PC somehow using the PS3 as a part of the PC.
the playstation store on your ps3 or the playstation store on your psp go.
No you cannot play the PC games on the PlayStation 3 or play PlayStation games on PC
The only way would be to purchase the Playstation game and have an emulator program for Playstation on the PC.
Ebay, amazon and many other online stores. Or you could download it from www.emuparadise.org and run it on PC using a PlayStation emulator. I don't know if writing the download onto a CD and using it in a playstation will work or not but it might if the playstation is chipped.
it really does depend on what platform your using... for instance, PlayStation 3, XBOX 360, PC etc... if your using PC you can press Esc and go on the controls options...
no not on any of the PlayStation consoles
