i want to sale computer for my needed but i am not sure which the better of them laptop or computer.
Welcome to the forums
Do you mean that you want to buy either a desktop PC or a laptop, but are unsure which one is right for you?
If that is the case, then I'm afraid that this is far too vague a question.
Consider starting a new thread and giving us more to go on: what would you use your laptop/PC for, where would you use it, what is your budget ...
In the meantime, THREAD CLOSED.
