These are number representation systems that can be applied to or used 
with integral, rational (numberator,denominator), and 'point' numbers.

Try Wikipedia or any search engine.

There are standard algorithms for converting between representations.
See above.  Good programmer calculators have these built in.

If you want to use the Python interactive interpreter, check the docs 
for the various integer literals and the hex, oct, and bin functions.
Binary literals and bin are only available in 2.6 (I believe) and 3.0 
(for sure).
