3400 B.C.

The concepts of analog and digital information, as we understand them today, did not exist in 3400 B.C. However, forms of both analog and digital-like information were present.

Analog information appeared in the form of cave paintings, carvings, music, speech, sundials, and shadows. These forms represented information continuously, corresponding to real-world phenomena occurring in 3400 B.C.

Digital information at the time was discrete and broken down into countable units, often used for record-keeping. Cuneiform writing and tally systems are examples of digital-like information that broke down data into individual units, similar to modern bits or characters.
