logical name
logical name. In NFS, a case-insensitive alphanumeric name that starts with a letter and
contains eight or fewer characters. Logical names are used to name LAN and SERVER
objects.
MAC address. See media access control (MAC) address
.
media access control (MAC) address. A 12-digit hexadecimal number used as an address
for network access. Each Compaq Tandem LAN Access Method (TLAM) controller is
assigned a unique MAC address, which is burned into its programmable read-only
memory (PROM) as part of the manufacturing process. Compaq, like other
manufacturers of IEEE 802.3 controllers, is licensed to use a dedicated range of MAC
addresses. That way, each controller is guaranteed its own unique address.
mount point. A directory that contains a mounted fileset. The mounted fileset can be in a
different file system.
multicast. A technique that allows copies of a single packet to be passed to a selected subset
of all possible destinations. Some hardware (for example, Ethernet) supports multicast
by allowing a network interface to belong to one or more multicast groups. Broadcast is
a special form of multicast in which the subset of machines to receive a copy of a packet
consists of the entire set.
Network File System (NFS). A protocol developed by Sun Microsystems, Inc. that uses
Internet Protocol (IP) to allow a set of cooperating computers to access each other’s
filesets as if they were all local. The key advantage of NFS over conventional file-
transfer protocols is that NFS hides the differences between local and remote files by
placing them in the same namespace. NFS is used primarily on UNIX systems, but it has
been implemented for many systems, including personal computers like the IBM PC and
Apple Macintosh computer.
NFS. See Network File System (NFS)
.
NonStop TCP/IP. See The product name for the OSS environments. See also Open System
Services (OSS)..
object. A programming procedure that provides named NFS services. NFS objects are
created by Subsystem Control Facility (SCF) commands.
Open System Services (OSS). A programming and software-execution environment that
provides UNIX-like facilities on a Himalaya system and is available for interactive or
programmatic use with the NonStop Kernel operating system. Processes that run in the
OSS environment use the OSS application program interface; interactive users of the
OSS environment use the OSS shell for their command interpreter. Contrast with

Open Systems Interconnection (OSI). A reference to protocols, specifically ISO standards,
for the interconnection of cooperative computer systems.
