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. Stream sockets provide a reliable and bidirectional communication channel between two processes. Data isare carried using the [[Transmission Control Protocol]] (TCP).

# <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

# <code>SOCK_RAW</code> will create an [[Internet Protocol]] (IP) [[datagram]] socket. Raw sockets skip the TCP/UDP [[transport layer]] and send the packets directly to the [[network layer]].<ref name="lpi-p1184">{{cite book
