Why does WikiAnswers incorrectly refer to UDP which stands for unreliable datagram protocol?
ANSWER According to W. Richard Stevens's book, TCP/IP Illustrated, Volume 1, UDP stands for User Datagram Protocol. It is unreliable, in the sense that there is no retrying defined in the protocol. This is in contrast to TCP, which stands for Transmission Control Protocol. TCP creates a connection layer on top of the unreliable internet Protocol (IP), by retrying the transmission of sequence-numbered packets so that the receiver can correctly reconstruct the data as it was sent. UDP just transmits the packet, and if any attempt at guaranteeing that a packet was received is needed, it must be done by the application level, not at the protocol level. Note that although it seems like an application should never use an unreliable protocol, the overhead involved in creating TCP connections is often deemed unnecessary, especially for operations done on LANs (ARP, BOOTP, etc).
What else can I help you with?
Which type of protocol is useful when data must be transferred fast?
connectionless protocols. A connection less protocol's lack of sophistication makes it more efficient than a connection-oriented protocol and renders it useful in situations in which data must be transferred quickly
Why do you have type data gram socket?
A datagram socket represents a connectionless, non-guaranteed communication protocol. It represents the UDP protocol in the TCP/IP suite.Contrast this with a stream socket, which represents a connection oriented, guaranteed, communication protocol. It represents the TCP protocol in the TCP/IP suite.UDP is the underlying protocol for TCP. If you are talking OSI model, UDP is layer 3, and TCP is layer 4.
What is difference between serial interface and Ethernet interface?
The FastEthernet interface of R1 is disabled. One of the default routes is configured incorrectly. A routing protocol is not configured on both routers. The default gateway has not been configured on both routers.
What the difference between protocol stack and protocol suite?
- In your own words, define the term 'protocol' and what is the difference between protocol and protocol suite
Is HTML protocol or not?
HTML is a protocol
What is a fast but unreliable delivery protocol that operates on the Transport layer?
This would be UDP. The User Datagram Protocol. It has no error checking or correction or congestion measures.
What is Full form of UDP Protocol in CCNA.?
user datagram protocol
IS TCP is unreliable Protocol?
No TCP a reliable protocol whereas UDP is unreliable.
What protocol does skype uses?
I believe Skype uses UDP or User Datagram Protocol.
What are three unique characteristics of UDP?
• low overhead • no flow control • no error-recovery function
What transport protocol does Skype use?
I believe Skype uses UDP or User Datagram Protocol.
What is the purpose of the Protocol field in an IP segment?
it indicates which layer 4 protocol is carried in a datagram
Which protocol is generating segments at the transport layer when using skype?
It is UDP the User Datagram Protocol.
Using which protocol do the hosts and the gateways send notification of datagram problems back to the sender?
ICMP protocol.
What stand for UDP?
This User Datagram Protocol (UDP) is defined to make available a datagram mode of packet-switched computer communication in the environment of an interconnected set of computer networks. This protocol assumes that the Internet Protocol IP is used as the underlying protocol. This protocol provides a procedure for application programs to send messages to other programs with a minimum of protocol mechanism. The protocol is transaction oriented, and delivery and duplicate protection are not guaranteed. Applications requiring ordered reliable delivery of streams of data should use the Transmission Control Protocol TCP. l
Protocol prepares data for transmission but has no resending capabilities?
UDP. User Datagram Protocol: A protocol that prepares data for transmission but that has no resending capabilities.
What protocol prepares data for transmission but has no resending capability?
UDP. User Datagram Protocol: A protocol that prepares data for transmission but that has no resending capabilities.
