Shared communication allows the infrastructure necessary for technology, trade, cultural exchange, and government to be developed and shared throughout the civilization.
Shared communication is another element that all civilizations share. Shared communication may include spoken language; alphabets; numeric systems; signs, ideas, and symbols; and illustration and representation. Shared communication allows the infrastructure necessary for technology, trade, cultural exchange, and government to be developed and shared throughout the civilization. The Inca civilization, for example, had no written script that we know of, but its complex khipu system of accounting allowed the government to conduct censuses of its population and production across the vast stretch of the Andes. A khipu is a recording device made of a series of strings knotted in particular patterns and colors.
