C16

C16 is an alphanumeric designation used across different domains to refer to distinct objects, codes, or models. In computing, Commodore 16 (C16) refers to a 1984 home computer by Commodore International, part of the C-Series. The C16 was designed as an affordable, entry-level machine and used the TED (Text Editing Device) chip for graphics and sound, with memory commonly listed as 16 KB of RAM and options for expansion. It was sold alongside other Commodore 8-bit machines but achieved modest commercial success compared to the C64.

In medicine, C16 is the ICD-10 code for malignant neoplasm of the stomach (stomach cancer), with subcodes for tumor location such as the cardia, antrum, or pylorus depending on specifics.

In chemistry, C16 denotes a molecule containing 16 carbon atoms. The designation appears in contexts such as straight-chain alkanes (for example C16H34) and in lipid shorthand like C16:0 for palmitic acid.

In other uses, C16 can appear as a designation in aviation, military, automotive, or electronics model numbers and project codes, where its exact meaning is defined by the relevant domain.
