ARPANET
ARPANET was the world's first operational packet switching network, and the progenitor of what would become the global Internet. Here are some key points about ARPANET:
History and Development
Technology and Protocols
- Network Interface Message Processor (IMP): Each site on ARPANET was connected through an IMP, which was essentially a small computer dedicated to managing network traffic.
- Packet Switching: ARPANET used packet switching to transmit data, allowing for more efficient use of network resources and resilience against failure.
- Network Control Protocol (NCP): Initially, ARPANET used NCP for communication, but this was later replaced by the Transmission Control Protocol (TCP) and Internet Protocol (IP) in the 1970s.
Impact and Evolution
Legacy
- ARPANET laid the groundwork for the development of the Internet, influencing the creation of numerous technologies and protocols.
- The lessons learned from ARPANET in terms of network design, reliability, and management have been instrumental in shaping the Internet's architecture.
