Difference between connectionless and connection oriented communication?
Different from a connectionless protocol, a connection-oriented protocol guaranties the delivery of the information. An example of connection-oriented protocol is (TCP) and a connectionless protocol is (UDP). page/926 A+
Why do you have type data gram socket?
A datagram socket represents a connectionless, non-guaranteed communication protocol. It represents the UDP protocol in the TCP/IP suite.Contrast this with a stream socket, which represents a connection oriented, guaranteed, communication protocol. It represents the TCP protocol in the TCP/IP suite.UDP is the underlying protocol for TCP. If you are talking OSI model, UDP is layer 3, and TCP is layer 4.
Which type of protocol is useful when data must be transferred fast?
connectionless protocols. A connection less protocol's lack of sophistication makes it more efficient than a connection-oriented protocol and renders it useful in situations in which data must be transferred quickly
Why Is HTML synchronous?
HTML is synchronous because the base protocol, HTTP (Hypertext Transfer Protocol) does not maintain a connection with the server. This was because, at the time, no one could imagine wanting a protocol that kept state. Give that the protocol doesn't track the user, there'd be no way for HTML to by asynchronous.
Which transport layer protocol provides low overhead and would be used for applications which do not require reliable data delivery?
UDP
