Windows has pretty the same socket model, from BSD. The difference is in the I/O event notification facility, for asynchronous network programming one would use "epoll" in Linux, "kqueue" in FreeBSD, they are conceptually pretty similar, while Windows has only the classic "select" and "poll", maybe something new windows-only thing (IOCP?) as well, but who cares.. Free Software rule.
