The <code>type</code> parameter will probably be one of two common socket types: stream or datagram.<ref name="lpi-p1151"/> A third socket type is available for experimental design: raw.
# <code>SOCK_STREAM</code> will create a stream socket. A stream socket provides a reliable, bidirectional, and [[connection-oriented communication]] channel between two processes. Data are carried using the [[Transmission Control Protocol]] (TCP).<ref name="lpi-p1151"/>
# <code>SOCK_DGRAM</code> will create a datagram socket.{{efn|A datagram ''socket'' should not be confused with a [[datagram]] [[Network packet|packet]] used in the [[network layer]].<ref name="lpi-p1183">{{cite book
