Historical contribution

What Davies contributed

Davies and his NPL team independently developed packet communication in the mid-1960s and introduced the term “packet” for small, standardised blocks of data routed through a network.

Why it mattered

Packet switching made interactive computer communication more efficient and resilient than reserving a complete circuit for every exchange.
