what is the key difference between tcp and udp?
82246
TCP is a connection-oriented protocol and UDP is a connection-less protocol. TCP establishes a connection between a sender and receiver before data can be sent. UDP does not establish a connection before sending data.

Which of the following are transport layer protocols used in networking? Explanation: Both TCP and UDP are transport layer protocol in networking. TCP is an abbreviation for Transmission Control Protocol and UDP is an abbreviation for User Datagram Protocol. TCP is connection oriented whereas UDP is connectionless.

There are some fundamental differences between TCP and UDP sockets. UDP is a connection-less, unreliable, datagram protocol (TCP is instead connection-oriented, reliable and stream based). ... recvfrom returns the IP address of the client, along with the datagram, so the server can send a response to the client.

The buffers for UDP packets are very limited in space which could cause UDP packets that are sent too fast not to be processed by the remote host. As a result of this, UDP port scanning is much slower than TCP port scanning and by default probes only a small number of ports (~ 180).

TCP port 1600 uses the Transmission Control Protocol. TCP is one of the main protocols in TCP/IP networks. TCP is a connection-oriented protocol, it requires handshaking to set up end-to-end communications. ... Guaranteed communication over TCP port 1600 is the main difference between TCP and UDP.

15 Answers. UDP is faster than TCP, and the simple reason is because its non-existent acknowledge packet (ACK) that permits a continuous packet stream, instead of TCP that acknowledges a set of packets, calculated by using the TCP window size and round-trip time (RTT).

TCP is used to control segment size, rate of data exchange, flow control and network congestion. TCP is preferred where error correction facilities are required at network interface level. UDP is largely used by time sensitive applications as well as by servers that answer small queries from huge number of clients.

RTP traffic can be interleaved over a TCP connection. In practice when this is done, the difference between Interleaved RTP (i.e. over TCP) and RTP sent over UDP is how these two perform over a lossy network with insufficient bandwidth available for the user.

TCP and UDP are both very well-known protocols, and they exist at Layer 4. TCP favors data quality over speed, whereas UDP favors speed over data quality. Layer 3 (Network) transmits data segments between networks in the form of packets.

Yes, you can use the same port number for both TCP and UDP. ... Technically the port pools for each protocol are completely independent, but for higher level protocols that can use either TCP or UDP it's convention that they default to the same port number.

Difference between TCP and UDP TCP reads data as streams of bytes, and the message is transmitted to segment boundaries. UDP messages contain packets that were sent one by one. It also checks for integrity at the arrival time. TCP messages make their way across the internet from one computer to another.

DNS uses TCP for Zone transfer and UDP for name queries either regular (primary) or reverse. UDP can be used to exchange small information whereas TCP must be used to exchange information larger than 512 bytes. ... For example, a domain client finding a domain controller using DNS.

HTTP uses TCP because the files, images, web pages which we get from the remote host should not be dropped on the way and it should be delivered in order to the HTTP client. HTTP could also use UDP but usually not, if a UDP packet containing the first part of a web page is lost, then its not retransmitted.

The IP protocol deals only with packets, and TCP enables two hosts to establish a connection and exchange streams of data. TCP guarantees delivery of data and also guarantees that packets will be delivered in the same order in which they were sent.

User Datagram Protocol (UDP) The basic unit of data is a User datagram and the UDP protocol provides the same unreliable, connectionless service transferring user datagrams as the IP protocol does transferring its datagrams. The main difference is that the UDP protocol is an end-to-end protocol.

TCP and UDP are all about how the packets are made and sent. ... This makes TCP reliable and to a certain extent it can recover from problems and glitches in the network because corrupt and missing packets are resent. The advantage of TCP is reliability. The disadvantage is that checking and error correction is slow.

TCP/IP uses IP addresses to communicate, and a DNS server resolves oblect to IP addresses for all the transmission based items your network needs to communicate with, like PC's, servers, printers, etc. A domain controller on the other hand holds all of the other information about everything in your network.
