what is the main 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.

UDP stands for User Datagram Protocol. Recall that a datagram and a packet are more or less the same thing. UDP, also built on top of the IP protocol, works similarly to TCP, but is simpler and faster. The main difference is that UDP doesn't require the recipient to acknowledge that each packet has been received.

2. 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.

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.

Explanation: HTTP is an application layer protocol. Whereas TCP is a transport layer protocol.

FTP itself uses the TCP transport protocol exclusively, or in other words, it never uses UDP for its transport needs. ... FTP also is odd in the fact that it uses two ports to accomplish its task. It typically uses port 20 for data transfer and port 21 to listen to commands.

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.

DNS and some other services work on both the protocols. ... 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.

Use tcpdump to capture any UDP packets on port 8125. ... udp means that only UDP packets will be captured. Other types of packets we might capture could be tcp or icmp for example.

The Transmission Control Protocol (TCP) and the User Datagram Protocol (UDP) needed only one port for full-duplex, bidirectional traffic. ... They usually use port numbers that match the services of the corresponding TCP or UDP implementation, if they exist.

What is the major difference between TCP and UDP packets? UDP packets are sent with no verification method while TCP packets require verification of receipt. What protocol commonly operates on port 139 TCP on Windows based systems? You just studied 15 terms!

TCP/IP uses both session and presentation layer in the application layer itself. OSI uses different session and presentation layers.

TCP isn't more secure than UDP, it is more “reliable” as it is stateful and requires acknowledgment of each segment. UDP is stateless and just sends segments without knowing of the client gets them or not. ... Both protocols rely on other protocols to provide security.

TCP and UDP are the most commonly used connection protocols for data travel on the Internet. Learn why UDP is ideal for VoIP. In VoIP, audio samples are placed into data packets for transmission over the IP network. ... TCP is so prevalent on the Internet that it's typically combined with IP and written as TCP/IP.

The difference is that TCP is responsible for the data delivery of a packet , it guarantees that packets will be delivered in the same order in which they were sent. and IP is responsible for the logical(IP) addressing, IP protocol deals only with packets.

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.

SMTP uses port 25 and it has been allocated for both UDP and TCP. I have never seen use of UDP in SMTP. In TCP, a packet is sent and checked on the other end. If the checksum says the packet is corrupt, it is dropped and a request is sent to retransmit it.
