Individual packets of information

Question

Is it true that With datagram sockets, individual packets of information are transmitted?

Answer 1

It is true that the Datagram sockets are used in sending and receiving blocks of data. The data that transmitted through Datagram sockets is called datagram. For sending data, both the source socket and the name of one or more destination sockets, must be specified. For instance the send to function, which permits to specify both a source socket and the name of one or more destination sockets, is normally used to send data. The send function can also be used to send data, however because the send function does not allow to specify the name for the destination datagram socket, the name of the destination datagram socket must have been previously specified by the connect function. While for receiving data recvfrom function will be used.
