today something about network and IP
The Internet Formalities is designed benefit of use in interconnected systems of
packet-switched computer communication networks. Such a structure has been called a "catenet". The internet rules provides as a remedy for transmitting blocks of data called datagrams from sources to destinations, where sources and destinations are hosts identified at near fixed dimension addresses. The internet diplomacy also provides seeing that
fragmentation and reassembly of crave datagrams, if compelling, in behalf of transmission sometimes non-standard due to "piddling bundle" networks, see some request headers request headers.
The internet modules application fields in the internet header to chip and
reassemble internet datagrams when necessary representing sending through
"mignonne packet" networks.
The model of operation is that an internet module resides in each body engaged in internet communication and in each gateway that interconnects networks. These modules share common rules for
interpreting talk to fields and representing fragmenting and assembling internet datagrams. In combining, these modules (especially in gateways) secure procedures as a remedy for making routing decisions and other functions.
The internet protocol does not fix up with provision a reliable communication facility. There are no acknowledgments either end-to-end or hop-by-hop. There is no gaffe rule for observations, only a header
checksum. There are no retransmissions. There is no flow control.
