What is a Computer? Trailer (1970)

01 January 1970 19 mins

Explains the evolution and basic principles of computing. It starts with simple methods like using fingers or stones to count, progressing to the decimal system and the abacus for better efficiency. The narrative then introduces the binary system as the foundation of modern computing, showing how these bits can represent on/off states in devices like switches, lamps, or punched cards. It describes how early computers process data through input, storage, and output, with programs controlling operations via switches. The text covers flowcharts for logical problem-solving, binary logic circuits, and the computer’s strengths: fast calculations, complex switching, and vast storage. It highlights applications like automation, information retrieval, and space travel, where computers simulate conditions using alphanumeric data. Finally, it speculates on future possibilities while humorously suggesting counting sheep if the concept overwhelms, tying back to the opening metaphor.
