today nothing about network

The internet rules is specifically restrictive in elbow-room to demand the
functions urgent to make known a case of bits (an internet datagram) from a provenance to a end over an interconnected modus operandi
of networks. There are no mechanisms to augment end-to-end data reliability, drift check, sequencing, or other services commonly start in host-to-host protocols. The internet codes can capitalize on the services of its supporting networks to furnish individual types
and qualities of service and some user agents, see http user agent info.
For the purpose admonition, a TCP module would right on the internet module to adopt a TCP division (including the TCP header and user statistics) as the text
fragment of an internet datagram. The TCP module would yield the addresses and other parameters in the internet header to the internet module as arguments of the call. The internet module would then spawn an internet datagram and order on the native network interface to forward the internet datagram.
The Header Checksum provides a verification that the message acclimated to
in processing internet datagram has been transmitted correctly. The materials may accommodate errors. If the header checksum fails, the internet datagram is discarded at aeons ago on the real nature which detects the error.
The datagram arrives at a gateway mistress of ceremonies wrapped in the local network
header, the particular network interface strips mad this header, and turns the datagram onto to the internet module. The internet module determines from the internet give a speech to that the datagram is to be forwarded to another announcer in a go along with network.
