> function from {0,1}^N -> {0,1}^M

"{0,1}": the set containing the values 0 and 1

"{0,1}^N": a discrete n-dimensional space, where the possible values in each dimension are 0 or 1

So they're saying a computer takes a length N binary sequence input and produces a length M binary output.

(As for "what level is this", I didn't cover any of this in my double A-level[0] in maths/further maths, but I am covering it in brilliant.org and some popular maths books, so my best guess is it's first or second year degree level?)
