What protocol makes a connection checks whether the data is received and resends it if it is not?

Remember that all communication on a network happens by way of packets delivered from one location on the network to another. In TCP/IP, the protocol that guarantees packet delivery is TCP (Transmission Control Protocol). TCP makes a connection, checks whether the data is received, and resends it if is not.

Explain the difference between a connection-oriented protocol and a connectionless protocol and give an example of each?
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). TCP is a connection-oriented protocol, it makes a connection and checks whether the data is received, and resends if it is not. UDP is a connectionless protocol, it does not guarantee delivery by first connecting and checking whether data is received.
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.
What do the letters tcpip stand for?
TCP/IP is a very common type of network protocol.TCP stands for Transmission Control Protocol and is used to create data connections between computers. Primarily, it is a "connection oriented protocol" in a sense that every connection goes through a three-way-handshake (SYN, ACK/SYN, ACK) to establish a connection before data is transmitted. Once the connection is established, each data packet that is received by the destination computer triggers an ACK packet (short for Acknowledge) to say that the data was received without error. That ACK packet will not be sent if the data packet is not received or if the data packet does not match the CRC (Cycle Redundancy Check). If the computer that sent the data packet does not hear that ACK packet, it sends the data packet again. The majority of traffic on the internet is TCP.TCP can be easily compared to UDP (User Datagram Protocol) which does not create a "connection" or ask for a acknowledgment packet and therefor typically has less overhead and latency. With UDP, data is sent to an address without worry for whether or not it reached its destination successfully. It is often used for streams such as internet radio/audio or video.IP stands for Internet Protocol. IP is the framework that lets computers address and communicate with each other. Most commonly known is an IP Address. An IP Address is a set of numbers given to a computer so that it may communicate with other computers with IP addresses. A common analogy is the phone system. To talk to someone, you simply dial their number.For example, to submit this answer, my computer made a TCP connection to wiki.answers.com's IP address and sent a data stream containing my writings. After each packet my computer sent, wiki.answers.com sent an acknowledge packet back.
Which protocol provides connectionless network service?
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.
Verification of the money sent through moneygram?
To verify whether the money you sent was received you can:Call the recipient and ask him whether he received the moneyCall MoneyGram and ask them to investigate whether the money was received
What protocol responds to Ping requests?
A ping command is used to check whether the host is alive or not. A ping command is used when you want to check if the host can send or receive packets. The protocol that is responsible for Ping command is ICMP.
Is there any application form for new connection of Cesc limited?

Why is the only address internet explorer goes to is the loop back address?
Then you may not have an Internet connection, or Internet Explorer may have a configuration problem. To see whether you have basic Internet connection (independent of Internet Explorer), use the "ping" command.Then you may not have an Internet connection, or Internet Explorer may have a configuration problem.

Does n protocol work backwards compatible?
Sort of. Almost all Wireless N routers support the G protocol aswell, so will be compatible with these devices. Whether they benefit from the extra range, I do not know.
Which tool can you use to determine whether a workstation is transmitting packets in proper Ethernet frame type for your network?
You need a protocol analyzer or a packet sniffer. They will capture packets and attempt to analyze them for proper protocol.
Filters decide whether to allow or block packets based on information in the protocol headers?

If out of order or missing packets create problems for the application using the data which services have to resolve these issues?
Since IP is an unreliable, Best-effort Protocol, it is unaware of the quality of job it is performing. IP packets are sent without certainty that they will be received. The IP protocol makes a best-effort to deliver packets, but it has no way of determining whether the packets are delivered successfully or whether they are lost en route. IP has no way to inform the sender of reliability problems. Thus, TCP can be relied on to inform the sender of delivery problems.
