History of computer science probability theory to the problem of how to best encode the information a sender wants to transmit. This work is one of the theoretical foundations for many areas of study, including data compression and cryptography .

Wiener also compared computation, computing machinery, memory devices, and other cognitive similarities with his analysis of brain waves. The first actual computer bug was a moth. It was stuck in
