SN1 is a unimolecular nucleophilic substitution reaction. They typically have 2 or more steps involving a carbocation intermediate which is attacked by a nucelophile.
SN2 is a bimolecular nucleophilic substitution reaction. It is a one-step reaction that involves a backside attack of the nucleophile on the electrophile and a stereochemical inversion.
E1 is a unimolecular elimination reaction. It involves formation of a carbocation followed by deprotonation.
E2 is a bimolecular elimination, in which the leaving group departs at the same time as the deprotonation.
