Control Protocol) NPC replaced by TCP (Transmission

Control Protocol) TCP worked better with added

verification of files

ARPANET

Packet Switching

Long range missiles found in Cuba Previously using centralized

networks Networks needed to be

decentralized Previously using radio waves Communication needed reliable

transfer during Atomic activity Distributed Network created

Nuclear/Atomic Threat

Multiple network communication Standardization “inter-net” was born Direct transfer of information Hardware for transfer instead of

software

CYCLADES

Phone company developed x.2 protocol

Allowed communication through phone servers in exchange for a monthly fee
