What else can I help you with?
Is email connection oriented or connectionless?
Email runs SMTP (simple mail transfer protocol), where SMTP operates over TCP protocol, so it id connection oriented.
What is NetWare connectionless protocol?
First let me explain the difference between connection oriented and connectioinless oriented. We'll use you as an example, Lets say you want to send an email to your friend in Australia. You need a system called a protocol to set up your system before you send the message. First a connection has to be made with your buddies Internet supplier, then once the connection is made you can send your email, then you want to make sure he got your email and then you want to end the session so someone else can use the system. On a connection protocol, the protocol first establishes a connection, then waits for a signal from the receiver to make sure the system is clear, then the data is sent, then it waits for a signal to say the data was received, then the session is closed. On a connectionless protocol, the session is established, the data is sent, and then the session is closed. So there is no confirmation if the data was received. That is what connectionless means, Netware uses a Transport protocol called IPX which is a connectionless protocol. So that is where the name came from.
Difference between connection - oriented and connectionless services?
Two distinct techniques are used in data communications to transfer data. Each has its own advantages and disadvantages. They are the connection-oriented method and the connectionless method:Connection-oriented Requires a session connection (analogous to a phone call) be established before any data can be sent. This method is often called a "reliable" network service. It can guarantee that data will arrive in the same order. Connection-oriented services set up virtual links between end systems through a network, as shown in Figure 1. Note that the packet on the left is assigned the virtual circuit number 01. As it moves through the network, routers quickly send it through virtual circuit 01.Connectionless Does not require a session connection between sender and receiver. The sender simply starts sending packets (called datagrams) to the destination. This service does not have the reliability of the connection-oriented method, but it is useful for periodic burst transfers. Neither system must maintain state information for the systems that they send transmission to or receive transmission from. A connectionless network provides minimal services.
Which protocol is used by a client to retrieve an email from a remote server using a TCP IP connection?
POP (post office protocol) is usually used to retreive emails from a server.
What are the different types of email mailboxes?
"Well, most email mailboxes use either POP3 or IMAP to retrieve your emails." Most email programs support both POP3 (Post Office Protocol) and IMAP (Internet Message Access Protocol) for pulling emails from a TCP/IP connection.
What email protocol has the highest download speed?
The email protocol with the highest download speed is IMAP which also offers the most features. Another email protocol is POP3.
What layer protocol is used for email?
the protocol used for email is simple mail transfer protocol and the layer is transport layer.
What is a email protocol?
an email protocol is a method by which a communication channel is established between two computers and email is transferred between them
What is the protocol for specifically sending eMail?
SMTP Protocol
Which email protocol uses port 143?
The IMAP (Internet Message Access Protocol) email protocol usually uses port 143.
Types of email protocol?
types of e-mail protocol?
Which high level protocol runs over ip?
IP is used by many higher level network protocols, principally TCP and UDP. Many Internet software applications including Web browsers (HTTP), FTP clients, and email programs ( SMTP), rely on Internet Protocol.
