stateless Protocol:-
1).When stateless protocol is used between a server and the client, the server does not remember anything. It treats any message from a client as the client's first message and responds with the same effects every time
2). A stateless server does notkeeps state between connections.
=>So,When
you send a request to a stateless server, it does not create any objects that track information regarding your requests. If you "open" something on the server, the server retains no information at all that you have something open. A "close" operation would make no sense, since there would be nothing to close.
3). A stateless system can be seen as a box ,where at any point in time the value of the output(s)
depends only on the value of the input(s)
after a certain processing time.
4). A stateless protocol does not require the server to retain session information or status about each communications partner for the duration of multiple requests.
5). stateless sessinobean:can
not maintain the state,cannot
maintain the persistance(data
base),onece
sutdown
machine,we
cannot see that data,cannot
have the passivate,activate
states. ex:atm
mini statements.
Example =
UDP(User
Datagram
Protocol) , HTTP, NFS
Statefull
Protocol :-
1). Stateful
protocol means the server remembers what a client has done before.
2). .A stateful
server keeps state between connections.
=>
when you send a request to a stateful
server, it may create some kind of connection object that tracks what information you request. When you send another request, that request operates on the state from the previous request. So you can send a request to "open" something. And then you can send a request to "close" it later. In-between
the two requests, that thing is "open" on the server.
3). a stateful
system is like a state machine with "memory" as the same set of input(s)
value can generate different output(s)
depending on the previous input(s)
received by the system.
4). a protocol which requires the keeping of internal state is known as a stateful
protocol.
5). statefull
Protocol :- maintain the state,but
cannot maintain the persistance,once
we shutdown
the system the values stored in local hard disc,can
have the passivate
and activate states. ex:shopping
card
Example =
SMB, FTP,Telnet
- In your own words, define the term 'protocol' and what is the difference between protocol and protocol suite
HTTP is called a stateless protocol because each command is executed independently, without any knowledge of the commands that came before it. This is the main reason that it is difficult to implement Web sites that react intelligently to user input. This shortcoming of HTTP is being addressed in a number of new technologies, including ActiveX, Java, JavaScript and cookies.

Different from a connectionless protocol, a connection-oriented protocol guaranties the delivery of the information. An example of connection-oriented protocol is (TCP) and a connectionless protocol is (UDP). page/926 A+
In internet protocol suite UDP is the connectionless protocol. There is no initial communication between client and server. UDP will not check whether the transmission was successful.

SMTP is push protocol, stateful protocol which is used for sending Mails from Client to Client or Server to Server. Generally SMTP uses the encryption method of 7bit or 8bit ISCII but HTTP dose not use that. HTTP is pull protocol which is preferred for sites demand and this is stateless protocol.

etiquette is what, and protocol is when
The difference between a link and an interface is the protocol used.
There is no notable difference.
both are same...
the two are not synonymous . you cant compare them Think of a protocol as a set of rules.
A stateless firewall does not keep information about existing connections, TCP sequence numbers, and other information. It analyzes packets independently, not as part of the packet sequence.
ISL IS A CISCO PROPRIETARY TUNNELING PROTOCOL, BUT 802.1 q IS A OPEN STANDARD PROTOCOL
The Kyoto Protocol is an international agreement while the Copenhagen Accord is a political agreement.
SSL (Secure Socket Layer,) is a protocol. Most Cisco VPNs will use SSL as their security protocol, so there is no difference between Cisco VPN and SSL VPN.
