User Datagram Protocol (UDP) works on the transport layer which is the third layer of the TCP/IP protocol suite. In contrast to the TCP protocol, it is a connectionless protocol as it does not establish a connection before sending the data over the network for communication. Thus it is bes...
A UDP port, on the other hand, doesn’t need users to establish a connection between the sender and the receiver to send the information. However, unlike a TCP port, the information sent over the UDP port may not reach the receiver. It is similar to sending a letter. It is not...
TCP is a connection-oriented protocol, while UDP is a connectionless protocol. TCP offers extensive error-checking procedures. In comparison, UDP only performs basic fault-monitoring mechanisms. TCP sends data packets in a specific order, while UDP doesn’t. ...

Unlike TCP, UDP is classified as a datagram protocol, or connectionless protocol, because it has no way of detecting whether both applications have finished their back-and-forth communication. Instead of correcting invalid data packets, as TCP does, UDP discards those packets and defers to the ...
That’s why TCP is more expensive than UDP, and UDP is less reliable than TCP. But you can use UDP in certain situations like Domain Name System (DNS) lookup, streaming files, Voice over Internet Protocol (VoIP), etc. Now that you know about TCP, it’s time to learn about IP too ...
Establishing a TCP connection requires that both the client and server participate in what is known as athree-way handshake. The process can be broken down as follows: A client sends the server a SYN packet—a connection request from its source port to a server’s destination port. ...
Along with TCP, UDP is also part of this layer. Application layer: The top layer controls communication between applications across the network. Protocols such as HTTP and FTP are crucial for the application layer. Email communication protocols (such POP or SMTP) also operate on this layer....
Overall, TCP and UDP are both useful protocols, so to think in terms of TCP vs UDP is a bit misleading. But depending on the type of data transfer, TCP or UDP might be better for the job. Here are some examples: TCP is best for: ...
What is UDP/IP? The User Datagram Protocol, orUDP, is another widely used transport protocol. It is faster than TCP, but it is also less reliable. UDP does not make sure all packets are delivered and in order, and it does not establish a connection before beginning or receiving transmissi...
