what is the major difference between tcp and udp packets?

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.

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.

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.

Side note: TCP port 99 uses the Transmission Control Protocol. TCP is one of the main protocols in TCP/IP networks. ... TCP guarantees delivery of data and also guarantees that packets will be delivered on port 99 in the same order in which they were sent.

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.

TCP is a connection-oriented protocol, whereas UDP is a connectionless protocol. The speed for TCP is slower while the speed of UDP is faster. TCP uses handshake protocol like SYN, SYN-ACK, ACK while UDP uses no handshake protocols. ... TCP has acknowledgment segments, but UDP does not have any acknowledgment segment.

UDP sockets are “message-oriented sockets” (as opposed to “stream-oriented sockets”; TCP sockets are stream-oriented). This is why the option we enable to use TCP in Nslookup is called the Virtual Circuit (VC) .

ICMP has no ports and is neither TCP nor UDP. ICMP is IP protocol 1 (see RFC792), TCP is IP protocol 6 (described in RFC793) and UDP is IP protocol 17(see RFC768). UDP and TCP have ports, ICMP has no ports, but types and codes.

Internet protocol suite The transport layer PDU is the TCP segment for TCP, and the datagram for UDP. The Internet layer PDU is the packet.

TCP and IP are two protocols belonging to different layers in the OSI model stack. ... → TCP is responsible for the data delivery of a packet and IP is responsible for the logical addressing. → Means, the IP obtains the address and TCP guarantees delivery of data to that address.
70068
The difference is that TCP is responsible for the data delivery of a packet and IP is responsible for the logical addressing. In other words, IP obtains the address and TCP guarantees delivery of data to that address.

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 is a standard protocol used for every network including the Internet, whereas, OSI is not a protocol but a reference model used for understanding and designing the system architecture. TCP/IP is a four-layered model, whereas, OSI has seven layers. ... TCP/IP is Tangible, whereas, OSI is not.

In short, TCP is reliable and guaranteed but UDP is not guaranteed. ... TCP provides ordering guaranteed which means the message will be received in the same order they are sent, UDP protocol doesn't provide such guarantee. TCP is a connection-oriented protocol as compared to UDP which is connectionless.

While TCP can be used for SNMP, it was originally designed with UDP transport only. While UDP may not have all the functionality of TCP, this actually makes it better for some applications.

UDP (User Datagram Protocol) is a communications protocol that is primarily used for establishing low-latency and loss-tolerating connections between applications on the internet.

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.
