Payload is the actual data which is being transmitted (as opposed to the headers and routing information).
Routers Drop a lot of UDP packets
UDP is much simpler than TCP. UDP does not do any sort of handshaking, connection establishment, or acknowledgements for received packets. UDP packets are simply sent over the network with no expectation of a return message. Since there are no methods for acknowledging that a packet has been received within UDP, there is no guarantee of the order in which packets will arrive. Sometimes, they may be lost all together. UDP is not the most reliable protocol within the IP suite, but it does have several important uses.Q. Which is an important characteristic of UDP?Simply answer is A.) · minimal delays in data delivery.In other words there are minimal delays in the travel of data from the sender to the receiver.
DNS primarily uses the User Datagram Protocol (UDP) on port number 53 to serve requests. DNS queries consist of a single UDP request from the client followed by a single UDP reply from the server. When the length of the answer exceeds 512 bytes and both client and server support EDNS, larger UDP packets are used.
datagram is used in conectionless n/w e.g. UDP Whereas packets used in connection oriented n/w e.g. ATM X.25 tcp

No it uses UDP packets.
No, UDP (User Datagram Protocol) does not guarantee the delivery of packets. It is a connectionless protocol that sends packets without establishing a connection or ensuring that they arrive at their destination. This means packets can be lost, duplicated, or delivered out of order. UDP is often used in applications where speed is critical and some data loss is acceptable, such as in streaming media or online gaming.
UDP does not require as much resources as TCP but in the same time, it does not insure delivery of packets.

If you mean TCP or UDP data packets, then no, they make up every data transmission on the net.
UDP
UDP - primarily for speed is used to transport voice packets in a VoIP deployment.
Only TCP will automatically discard a packet with a bad checksum. UDP packets have a checksum field, but it is rarely used, and then only by the application (not UDP itself)
1500 Bytes
The correct answer is IP. IP is responsible for breaking data into packets and passing them from TCP or UDP to the hardware.
A UDP (User Datagram Protocol) request is a type of network communication that involves sending data packets without establishing a connection between the sender and receiver. Unlike TCP, UDP is connectionless and does not guarantee delivery, order, or error-checking, making it faster but less reliable. It is commonly used for applications where speed is essential, such as video streaming, online gaming, and voice over IP (VoIP). UDP packets are called datagrams and are sent independently of one another.
