;Internet Protocol
:IP is an addressing and fragmentation protocol. It breaks all communications into packets, chunks of data up to 65536 bytes long. Packets are individually routed from source to destination. IP is allowed to drop packets; i.e., it is an unreliable protocol. There are no acknowledgements and no retransmissions. There is no flow-control such as there is in a RS-232 serial interface.
