TCP and UDP are both communication network protocols.
TCP protocol in its essence is to guarantee delivery of information, and in the order sent.
UDP protocol is lighter, by fact of not checking for the connection to be ready to receive on the other end, not checking if the information getting to the other end is correctly received.

Which protocal is required on any computer that communicates across the internet?
IP, or Internet Protocol, is required to use the public Internet. While sometimes called "TCP/IP", TCP-Transmission Control Protocol-is only one part of the Internet Protocol suite, which includes many others, such as UDP (User Datagram Protocol), ICMP (Internet Control Message Protocol), etc.
Explain the difference between a PDU and a datagram?
A PDU (Protocol Data Unit) is defined by which layer it is in. In the physical layer and network layer, it is synonymous with the packet, in the data link layer, it is the frame. In the transport layer, it is a datagram for UDP. A datagram holds one or more PDU's, as it is the basic unit of transferring information via packet switching.
What is the difference between RTCP and RTP?
RTP (Real-time Transport Protocol): Carries the voice and video traffic and doesn't do any signalling, signaling is done by H.323, MGCP or SIP protocols. Its uses UDP to carry the payload hence its not actually a protocol Where RTCP (Real-time Transport Control Protocol) Manages the quality of RTP such as QOS Identification, Session size estimation and scaling and basically works with RTP side by side.
What is the difference between a PDU and a datagram?
This is a more generic term that is often used in describing protocols that function at higher levels of the OSI model, ususally the network layer and up. Datagram is a less specific term than PDU.Datagrams contain logical addressing information, such as an IP address, logical connection identifiers, such as port numbers, and data that came from a computer application. The UDP protocol does not guarantee delivery of the datagrams.A PDU is a Power Distribution Unit.I have added a link to a PDU from Intro Delta to show you what one is.
Router work in which layer of osi model?
Routers work in layers two, three, and four layer 1 Physical (copper, fiber,...) layer 2 Datalink (ethernet, token ring, ...) 2->3 providing address resolution (ARP) ie. media access control (MAC) to IP translation layer 3 Network (IP,IPX,RIP,...) 3->4 providing routing layer 4 Transport provides error handling in connectin oriented delivery and handles connectionless delivery Conneciton Oriented(TCP,SPX) Connectionless (UDP)
What is the most significant difference between the Layer 4 TCP and the Layer 4 UDP?
the main difference between UDP and TCP is that UDP is not a reliable protocol.
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.
How java supports networking?
Java supports both TCP and UDP connections. ServerSocket and Socket classes exist for TCP. DatagramSocket exists for UDP.
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.
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.
What is a TCP or UDP socket?
UDP and TCP sockets are layer 4 ports which are associated with certain services, ie TCP80 refers to the HTTP (web) protocol, TCP443 refers to the HTTPS (SSL) secure protocol and TCP/UDP53 refers to DNS.
What is fastest udp or tcp?
UDP
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 .
Does sftp use tcp or udp?
TCP
Which Protocols Does Does The Netstat -s Command Print Information?
Netstat reports on the common tcp/ip protocols, including (but not limited to) TCP, UDP, ICMP, socket connections.
About which protocols does the netstat -s command print information?
Netstat reports on the common tcp/ip protocols, including (but not limited to) TCP, UDP, ICMP, socket connections.
What is the Difference between the TCP and UDP in computer networking?
An important difference is that TCP includes mechanisms for reliable data communication (lost parts of the communication are re-sent), UDP doesn't. TCP is used when such a reliable communication is important. When speed is more important than reliability, UDP is used instead. This is the case with phone or video communication over the Internet.An important difference is that TCP includes mechanisms for reliable data communication (lost parts of the communication are re-sent), UDP doesn't.
