Is UDP connection oriented?
No
When is UDP preferred to TCP?
UDP and TCP both are transport layer protocols. UDP is connection less and TCP is connection oriented. UDP is preferred over TCP when large amount data is to be sent like on skype or video conferencing .
Difference TCP and UDP?
TCP is the protocol of network layer, It is connection oriented protocol. UDP is the protocol of network layer, It is connection less protocol.
Why should telnet to UDP port fail?
A single port can be configured to listen for UDP or TCP inbound connection requests (or both). Telnet uses TCP. So when you telnet to a specific IP:port, telnet will attempt to make a TCP connection. If there is no TCP listener on the port you specify, then the connection request will be refused. It matters not if you have a UDP listener on the port. Telnet will not be able to establish a connection to a UDP port.
Which transport layer protocol does not maintain a connection state?
UDP
What is the main difference between TCP and UDP?
in udp there is no check for error detection as well as the packect has reached to destination or not. where as tcp takes care of all this that's why it is slower than udp.
Udp is said to be based?
UDP is said to be transaction-based, because it focuses only on the transaction of data. Not on the connection like TCP does.
What are 2 features of the UDP?
its an connection less does not support broad casting
How many fields are there in IPv4 header?
UDP is a Transport layer protocol or fourth layer protocol. UDP is a connection less protocol used in transport layer. UDP header have four fields in total .
Why does DNS run over udp?
DNS runs over UDP because the UDP does not have any delay to establish the connection, which DNS will have finer application level control for faster connection speed in comparison to TCP protocol.
What application layer protocol is commonly used to support for the file transfers between client and server?
You can use either TCP or UDP. If you need reliable connection use TCP otherwise UDP.
Is DNS connectionless or connection-oriented?
DHCP is a connectionless protocols. In general, any protocol that is based on TCP port alone is a connection-oriented protocol while any protocol that is based on UDP port alone is a connectionless protocol. And a protocols that can work on both TCP and UDP port can be either a connection-oriented or a connectionless protocol depending upon the which protocol is used (TCP or UDP). For checking other protocols if they are connection-oriented or connectionless check http://en.wikipedia.org/wiki/List_of_TCP_and_UDP_port_numbers
