Anything with an integer spin is a Boson. That's spin 0, 1, 2, ... etc.
So, for example, a proton has spin 1 and is a boson. Electrons, by contrast, have a spin of +/- 1/2. Anything with an half-integer spin is a Fermion. Another example of a boson would be a composite particle, such as say a proton and neutron stuck together, which has a spin 1+1=2. (protons are actually composite particles themselves: they are made up of quarks, which i think have spins in multiples of 1/3).
this is a good website for a very conceptual and somewhat superficial understanding of particle physics.
this is a GREAT website for a pretty good understanding of most fields in physics.
