Where can I get a comparison about postgraduate courses ( MSc degree ) related to Computer Science in UK vs US?

Particularly regarding
1) Duration
2) Tuition fees
3) Living Expenses
4) Possible Financial Aid

(I am a South Asian student who will be completing a BSc degree in Computer Science next year.)

I don't know the answer to your question as a whole, but re 4) in the UK for an overseas student I do know is very unlikely indeed.
