Depends what kind of phone you are using. Apple phones can be reset to factory default through Itunes for example. (Factory default means the phone resets to before the user, you, got it).
Windows phone can factory reset on it's own for what I know. I suggest you trying to find your phone in google. For example I got a Samsung Galaxy S4.
You go into google and type "Factory reset Samsung galaxy s4".
If you are going to use a pc, you'll want to use a usb cable to connect your phone and pc. From your pc you could delete files that are on a memory card if you have those (android phones can have a memory card, iphones cant)
Hope this helped
