Both are short range fundamental forces mediated by vector gauge bosons.

The strong force has a larger coupling constant than the weak force (i.e. it is stronger). The typical interaction range of the strong force is much shorter than the weak force. The strong force couples to (interacts with) particles that carry colour charge (quarks, gluons and particles made of quarks & gluons), whereas the weak force couples to all known fermions (quarks and leptons). The strong force is mediated by a massless particles called gluons between coloured particles, and virtual pions between colour-neutral particles. Gluons keep the quarks together that make up protons and neutrons. Pions carry the force between protons and neutrons to keep the nucleus together. The weak force, on the other hand, is mediated by three fundamental massive gauge bosons: the W+, W- and the Z0. The W+ and W- bosons can couple to the Z0 and the photon. The gluon cannot. The strong force is confining and non-perturbative because the gluon interacts with itself. This means you can never observe a quark on its own. Pulling quarks apart has the effect of creating more quarks out of the energy provided. The weak force does not behave like this. The weak force treats matter and antimatter slightly differently (something called CP violation). CP violation has never been observed in the strong force, although it is not impossible mathematically.
