Do both LINK 480Z and CARDboard Illustrative Aid to Computation both involve computers?
CARDboard Illustrative Aid to Computation CARDIAC (CARDboard Illustrative Aid to Computation) is a learning aid developed by David Hagelbarger and Saul Fingerman for Bell Telephone Laboratories in 1968 to teach high school students how computers work. The kit consists of an instruction manual and a die-cut cardboard "computer".
Document A document is a written, drawn, presented, or memorialized representation of thought. The word originates from the Latin "documentum", which denotes a "teaching" or "lesson": the verb "doceō" denotes "to teach". In the past the word was usually used to denote a written proof useful as evidence of a truth or fact. In the computer age, "document" usually denotes a primarily textual computer file, including its structure and format, e. g. fonts, colors, and images. Contemporarily, "document" is not defined by its transmission medium, e. g., paper, given the existence of electronic documents. "Documentation" is distinct because it has more denotations than "document". Documents are also distinguished from "realia", which are 3 dimensional objects that would otherwise satisfy the definition of "document" because they memorialize or represent thought; documents are considered more as 2 dimensional representations.
