xD I don't know if you said this as a joke, or if you're serious, but here:
A computer can be a helpful tool to complete your homework by giving you access to countless sources of information, it can also provide you with educational games which can enhance a child's learning ability by presenting learning as something fun and interactive as opposed to boring loads of repeated work which barely stimulate learning at all. But keep in mind that a computer can also take the opposite effect on a child's brain, and can gradually turn into addiction.
I hope this helps! :D
(FYI, I spent an unreasonable amount of time typing this all in, so I hope it makes any difference at all :P)
