file system
The term file system is often used interchangeably with fileset in UNIX publications.
file system. In the Open System Services (OSS) environment, a collection of files and file
attributes. A file system provides the namespace for the file serial numbers that
uniquely identify its files. Open System Services provides a file system (see also
ISO/IEC IS 9945-1:1990 [ANSI/IEEE Std. 1003.1-1990], Clause 2.2.2.38); the
Guardian application program interface (API) provides a file system; and OSS Network
File System (NFS) provides a file system. (OSS NFS filenames and pathnames are
governed by slightly different rules than OSS filenames and pathnames.) Within the
OSS and OSS NFS file systems, filesets exist as manageable objects.
On an HP NonStop™ system, the Guardian file system for an Expand node is a subset
of the OSS virtual file system. Traditionally, the API for file access in the Guardian
environment is referred to as the Guardian file system.
In some UNIX and NFS implementations, the term file system means the same thing
as fileset. That is, a file system is a logical grouping of files that, except for the root of
the file system, can be contained only by directories within the file system. See also
fileset.
file transfer protocol (FTP). (1) The Internet-standard, high-level protocol for transferring
files from one machine to another. (2) The application used to send complete files over
Transmission Control Protocol/Internet Protocol (TCP/IP) services.
FIPS. A Federal Information Processing Standard of the United States government.
FIPS 151-1. The Federal Information Processing Standard that specifies the requirements
for conformance to an older draft of POSIX.1 than the version adopted as ISO/IEC IS
9945-1:1990 (FIPS 151-1 describes conformance to IEEE Std. 1003.1-1988) and
imposes some additional requirements.
FIPS 151-2. The Federal Information Processing Standard that specifies the requirements
for conformance to POSIX.1 as ISO/IEC IS 9945-1:1990 and imposes some additional
requirements.
foreground process group. A process group whose members have privileges for access
to their controlling terminal that are denied to processes in background process groups
of that terminal. Each session with a controlling terminal has only one foreground
process group for that terminal. Contrast with background process group.
FTP. See file transfer protocol (FTP).
group ID. The nonnegative integer used to identify a group of users of an HP NonStop
network node. Each user of that node is a member of at least one group. When the
identity of a group is associated with a process, a group ID value is referred to as one
of the following identifiers:
•
Real group ID
•
Effective group ID
•
Supplementary group ID
