today something about network and IP

The internet protocol is specifically minimal in field to prepare for the
functions vital to deliver a case of bits (an internet datagram) from a horse's mouth to a target more than an interconnected system
of networks. There are no mechanisms to augment end-to-end observations reliability, stream sway, sequencing, or other services commonly establish in host-to-host protocols. The internet protocol can capitalize on the services of its supporting networks to provide distinct types
and qualities of service and some user agents, see whats my user agent.
The internet modules use fields in the internet header to split up and
reassemble internet datagrams when imperative for the treatment of sending by way of
"mignonne pretty penny" networks.
The Header Checksum provides a verification that the news acclimated to
in processing internet datagram has been transmitted correctly. The text may contain errors. If the header checksum fails, the internet datagram is discarded at once beside the essence which detects the error.
The internet protocol does not offer a reliable communication facility. There are no acknowledgments either end-to-end or hop-by-hop. There is no error lead in the interest observations, only a header
checksum. There are no retransmissions. There is no flow control.
