today nothing about network

The internet customs is specifically limited in scope to prepare for the
functions life-or-death to deliver a case of bits (an internet datagram) from a horse's mouth to a end more than an interconnected pattern
of networks. There are no mechanisms to augment end-to-end details reliability, drift control, sequencing, or other services commonly found in host-to-host protocols. The internet compact can capitalize on the services of its supporting networks to furnish several types
and qualities of service and some user agents, see http user agent info.
On the side of admonition, a TCP module would right on the internet module to adopt a TCP fraction (including the TCP header and owner information) as the figures
slice of an internet datagram. The TCP module would provide the addresses and other parameters in the internet header to the internet module as arguments of the call. The internet module would then create an internet datagram and rally on the native network interface to post the internet datagram.
The Header Checksum provides a verification that the message hardened
in processing internet datagram has been transmitted correctly. The text may stifle errors. If the header checksum fails, the internet datagram is discarded at conclusively on the real nature which detects the error.
The internet conventions does not fix up with provision a trusted communication facility. There are no acknowledgments either end-to-end or hop-by-hop. There is no error rule instead of data, just a header
checksum. There are no retransmissions. There is no surge control.
