2i1
2i1 is an alphanumeric designation used in various industries as a label for products, components, or documentation. There is no universally defined meaning for "2i1"; its interpretation is context-dependent and determined by the issuer, such as a manufacturer, retailer, or standards body. In marketing materials, 2i1 is often treated as an indicator of dual functionality, sometimes read as "two-in-one" (two features combined into a single unit). However, this interpretation is not universal and should not be assumed without corroborating information from official product literature. In hardware catalogs or parts databases, 2i1 may function as a model number, a batch or version code, or an internal classification that encodes other attributes (for example generation, interface, or configuration). Because the designation is not standardized, the same code can appear on different products with different meanings.
Etymology and usage notes: The digits and letters in the code are typically chosen by the issuing
