Acids ionize to produce hydrogen ions; bases ionize to produce hydroxide ions.
An acid donates a proton to a base; a base accepts a proton from an acid.
This definition of a so-called "proton" acid is often used in organic chemistry.
An acid accepts an electron pair from a base to form a covalent bond; a base donates an electron pair to an acid to form a covalent bond.
This is the widest of definitions of the acid/base concept and is also
of use in organic chemistry.
The Brønsted and Lowry concept is essentially the same as the Lewis concept with "acids" limited to protons.
A set of overheads reviewing acid base concepts is available:
