100series

100series is a designation used across multiple industries to label a family of related products or assets. It is not a single, standardized entity; the meaning of "100series" varies by company and domain. In general, the term is used to indicate either the first generation, a baseline configuration within a broader lineup, or a shared platform among members of the series. The form of the designation may appear as 100series, 100-series, or Series 100, depending on branding guidelines.

In transportation, many fleets reference a "100 series" class for vehicles that share a common architecture or design heritage. Within such a class, later sub-series (e.g., 101, 102) usually denote revisions, improvements, or regional variants while preserving core compatibility.

In consumer electronics and industrial equipment, 100series is commonly used to distinguish an initial product wave or a midrange/budget line within a manufacturer's catalog. The exact attributes—such as features, performance, or price tier—are determined by the producer, and the same naming could imply different positions in another company’s lineup.

In software, hardware, and infrastructure contexts, the 100 series may refer to generations of appliances, network hardware, or service platforms, again with varying criteria for what constitutes a generation.
