A font is a particular size, weight and style of a typeface. Each font is a matched set of type, one piece (called a "sort") for each glyph, and a typeface consists of a range of fonts that share an overall design. With the advent of digital typography, font is frequently synonymous with typeface, although the two terms do not necessarily mean the same thing. In particular, the use of "vector" or "outline" fonts means that different sizes of a typeface can be dynamically generated from one design. Each style may still be in a separate "font file" -- for instance, the typeface "Futura" may include the fonts "Futura roman", "Futura italic", "Futura bold" and "Futura extended" —- but the term "font" might be applied either to one of these alone or to the whole typeface.
