What uses UDP protocol?
UDP. UDP is the User Datagram Protocol, a simpler and faster cousin to TCP. … UDP is commonly used for applications that are “lossy” (can handle some packet loss), such as streaming audio and video. It is also used for query-response applications, such as DNS queries.
What are key elements of protocol?
A protocol is a set of rules that govern data communications. It defines what is communicated, how it is communicated, and when it is communicated. The key elements of a protocol are syntax, semantics, and timing.
What is the most important protocol used on the Internet?
The dominant internetworking protocol in the Internet Layer in use is IPv4; the number 4 identifies the protocol version, carried in every IP datagram. IPv4 is described in RFC 791 (1981).
Which protocol is used in Web?
Hypertext Transfer Protocol (HTTP) is a method for encoding and transporting information between a client (such as a web browser) and a web server. HTTP is the primary protocol for transmission of information across the Internet.
What are three network models?
Three types of network models and their associated distributions: (a) random network, (b) scale-free network, and (c) hierarchical network.

Common Internet protocols include TCP/IP (Transmission Control Protocol/Internet Protocol), UDP/IP (User Datagram Protocol/Internet Protocol), HTTP (HyperText Transfer Protocol) and FTP (File Transfer Protocol). TCP/IP is a stream protocol.
How does the Internet protocol work?
IP connects with hosts through interfaces. … It converts data into datagrams, which are the header info consisting of source/destination and metadata, and the payload, which is the data itself. IP encapsulates the data, nesting it into packets.
Why IP protocol is considered as unreliable?
The IP layer provides an unreliable, connectionless delivery system. The reason why it is unreliable stem from the fact the protocol does not provide any functionality for error recovering for datagrams that are either duplicated, lost or arrive to the remote host in another order than they are send.
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.
Why is UDP needed?
For real-time services like computer gaming, voice or video communication, live conferences; we need UDP. Since high performance is needed, UDP permits packets to be dropped instead of processing delayed packets. There is no error checking in UDP, so it also saves bandwidth.
What is the characteristics of UDP?
UDP uses a simple connectionless communication model with a minimum of protocol mechanisms. UDP provides checksums for data integrity, and port numbers for addressing different functions at the source and destination of the datagram.
What are two features of protocols?
TCP mechanisms retransmit data when an acknowledgment is not received from the destination system within a set period of time. The same Transport Layer source port is used for all of the tabs opened at the same time within a web browser.
What is the need of communication protocol?
Protocols are basically needed because it’s important for the receiver to UNDRSTAND the sender. In computer communications, protocols also make sure the message gets to its destination properly, in entirety, and with out distortion.
What is the need for Internet Protocol?
