| comp., MS | sparse array | matriz rala (An array (arrangement of items) in which many of the entries are identical, commonly zero. It is not possible to define precisely when an array is sparse, but it is clear that at some point, usually when about one-third of the array consists of identical entries, it becomes worthwhile to redefine the array) |
| comp., MS | sparse column | columna dispersa (A column that reduces the storage requirement for null values at the cost of more overhead to retrieve nonnull values) |
| comp., MS | sparse file | archivo disperso (A file that is handled in a way that requires much less disk space than would otherwise be needed. Sparse support allows an application to create very large files without committing disk space for those regions of the file that contain only zeros. For example, you can use sparse support to work with a 42-GB file in which you need to write data only to the first 64 KB (the rest of the file is zeroed)) |
