The document discusses the history of the Information Age from ancient times to the present. It divides this history into four periods: the Pre-Mechanical period from 3000 BC to 1450 AD, which saw the development of writing systems and early calculation tools; the Mechanical period from 1450-1840 that brought movable type printing and slide rules; the Electro-Mechanical period from 1840-1940 that introduced technologies like the telegraph, telephone, and early computers; and the modern Electronic/Information period from 1940 onward, where electronic computers were developed and advanced through generations using newer technologies like integrated circuits.
2. What is the Information Age?
People, Information & Societies that chronicle
the birth and growth of electronic information --
from ancient times to Samuel Morse's invention
of the telegraph in the 1830s, through the
development of the telephone, radio, television,
and computer.
