Please don't take this the wrong way Gemma, but based on your posts the past few days you really, really need to learn some basics about computers and digital photography. Something like "digital photography for dummies" might be a good place to start. You'd probably need to read "computers for dummies" before you an read the digital photography book.
I think you'd learn a lot, and it'd give you a basis to work things out for yourself in future, rather than asking what are honestly incredibly basic questions.
