What is UDP and its features?

The User Datagram Protocol (UDP) is simplest Transport Layer communication protocol available of the TCP/IP protocol suite. It involves minimum amount of communication mechanism. UDP is said to be an unreliable transport protocol but it uses IP services which provides best effort delivery mechanism.

What are the protocols of UDP?

The UDP protocol allows the computer applications to send the messages in the form of datagrams from one machine to another machine over the Internet Protocol (IP) network. The UDP is an alternative communication protocol to the TCP protocol (transmission control protocol).

What are the applications of UDP?

Numerous key Internet applications use UDP, including: the Domain Name System (DNS), the Simple Network Management Protocol (SNMP), the Routing Information Protocol (RIP) and the Dynamic Host Configuration Protocol (DHCP). Voice and video traffic is generally transmitted using UDP.

What is the main advantage of UDP?

What is the main advantage of UDP? Explanation: As UDP does not provide assurance of delivery of packet, reliability and other services, the overhead taken to provide these services is reduced in UDP’s operation. Thus, UDP provides low overhead, and higher speed.

What are the advantages of UDP?

Advantages of UDP :

  • UDP does not need to require a connection to be established and maintained.
  • UDP uses a small packet size with a small header.
  • UDP uses checksum with all packets for error detection.
  • UDP can be used in events where a single packet of data needs to be exchanged between the hosts.

Which three fields are used in a UDP?

Answers Explanation & Hints: Sequence Number, Acknowledgment Number, and Window Size are TCP header fields.

What is TCP and UDP used for?

Both TCP and UDP are protocols used for sending bits of data—known as packets—over the Internet. Both protocols build on top of the IP protocol. In other words, whether you’re sending a packet via TCP or UDP, that packet is sent to an IP address.

What is the advantage of UDP over TCP?

UDP is faster, simpler, and more efficient than TCP. Retransmission of lost packets is possible in TCP, but not in UDP. There is no retransmission of lost packets in the User Datagram Protocol (UDP).
