I discuss central questions of glass structure and define four ranges of order in an amorphous solid: short, intermediate, long and global. These concepts are used to catalog all of the elements of order in the Zachariasen-Warren model for a-SiO2, in preparation for a later deduction of the logically possible improvements in that model. Six existing approximate forms of the ZW model are discussed using the language developed in the paper. This provides a fundamental background regarding structure for the rest of the papers in this volume.
