stateful v stateless

stateful versus stateless conditions exist in many technologies and applications... firewalls, dhcp, ipv6, programming, protocols, ad nauseum... it seems every one of these define stateful and stateless in their own inimitable way, and as it concerns its particular  usage...

coming to terms with a useful definition that can encompass the whole is no easy task..

stateful: systems which track the state of the communication, protocol, event, instance or synchronization

stateless: no obligatory tracking of the state of communication, protocol, event instance or synchronization

one can make an analogy using the essential difference between udp and tcp

whereas  udp is connectionless (stateless),  tcp is connection oriented (stateful) because of built in reliability mechanisms

is this a stretch? i don't think so...

the advantage of a stateful state is a pre-determined guarantee at a cost of more overhead

the advantage of a stateless state is best effort with little reliance on resources
