(2) (Encapsulated PostScript) A PostScript file format used to transfer a graphic image between applications and platforms. EPS files contain PostScript code as well as an optional preview image in TIFF, WMF, PICT or EPSI, the latter being an ASCII-only format. Adobe Illustrator has its own variation of EPS, which is an EPS subset, thus, both Illustrator EPS and standard EPS files are in use.

From Drawing Program to Page Layout Program
A typical usage of EPS is to save an illustration created in a drawing program as an EPS file and to import it into a page layout program such as InDesign or QuarkXPress. The layout artist would place and resize the image, which would either be the embedded preview or rendered directly from the PostScript code. The EPS images would be saved in the page layout program.
