You're asking like UNIX is a kind of computer; it isn't.

UNIX can run on many kinds of processors and memories, on scales from embedded microcomputer(things like wireless routers) all the way up to distributed clusters and supercomputers.

There's also many kinds of kernels of several kinds you mention; there's real-tasking UNIXes(QNX), monolithic(Linux, though that's technically UNIX-like), and more.

How is this possible?

Easy -- they're not all the same thing. UNIX is a design plan, not an operating system. As long as your OS is certified as providing the right set of features, it can be considered a UNIX, no matter how it's built internally. Lots of different individuals and software companies have built a UNIX to their own design or need.

So, it's very difficult to be anything but vague about "what is UNIX" with respect to those particular questions. You need to be more specific about which UNIX.

net::ldapi

Net::LDAPI(3)						User Contributed Perl Documentation					     Net::LDAPI(3)

NAME

       Net::LDAPI - use LDAP over a UNIX domain socket

SYNOPSIS

	use Net::LDAPI;

	$ldapi = Net::LDAPI->new('/var/run/ldapi');

	# alternate way
	use Net::LDAP;

	$ldapi = Net::LDAP->new('ldapi://');

DESCRIPTION

       Communicate using the LDAP protocol to a directory server using a UNIX domain socket. This mechanism is non-standard, UNIX-specific and not
       widely supported.

       All the normal "Net::LDAP" methods can be used with a "Net::LDAPI" object; see Net::LDAP for details.

CONSTRUCTOR

       new ( [SOCKPATH] )
	   Create a new connection. SOCKPATH can optionally be specified, to specify the location of the UNIX domain socket to connect to.

	   If SOCKPATH is not given, the environment variable "LDAPI_SOCK" is evaluated, and if that does not exist, the value "/var/run/ldapi" is
	   used.

	   See "new" in Net::LDAP for further details.

SEE ALSO

       Net::LDAP, IO::Socket::UNIX

BUGS
