BIOS
|
|
A set of computer instructions in firmware that control input and
|
|
output operations.
|
|
|
|
CLI
|
|
Command Line Interface
|
|
|
|
Domain Specific Language
|
|
A special purpose programming language dedicated to a particular
|
|
problem area, e.g. SQL is a domain specific language for retrieval
|
|
of data from a database.

EPEL
|
|
Common acronym for Extra Packages for Enterprise Linux. These are
|
|
typically included in Fedora Linux, and provided for RedHat, CentOS,
|
|
and other RPM-based distributions. The project's homepage is
|
|
here: `FedoraProject:EPEL <http://fedoraproject.org/wiki/EPEL>`_.
|
|
|
|
GUI
|
|
Pronounced "gooey", this is an acronym for a Graphical User Interface.
|
|
This is distinctly different from a :term:`CLI`, in that the GUI typically can contain more complex visual interactions.

|
|
|
MAC
|
|
Pronounced as "mack" and often used as a noun referring to a network
|
|
device's Media Access Controller (MAC) address. A MAC address is a
|
|
globally unique number assigned to each interface in an Ethernet network
|
|
and used to direct Ethernet frames between source and destination
|
|
devices.
|
|
|
|
OSI
|
|
Open Systems Interconnection (OSI) is an effort to develop
|
|
standards-based computer networking protocols in order to allow
|
|
networking equipment from different vendors to interoperate without
|
|
relying on implementation of competing proprietary protocols. The OSI is
|
|
best known for the development of the standard seven-layer OSI model for
|
|
describing layers of abstraction into which the various networking
|
|
protocols are categorized.
|
|
|
|
POSIX
|
|
An acronym for "Portable Operating System Interface", is a family of
|
|
standards specified by the IEEE for maintaining compatibility between
|
|
operating systems. POSIX defines the application programming interface
|
|
(API), along with command line shells and utility interfaces, for
|
|
software compatibility with variants of Unix and other operating systems.

|
|
RFC
|
|
The RFC documents (Request for Comments) are a series of Internet
|
|
standards, best common practices, and related documents describing how
|
|
networked computers communicate. This document series provides the
|
|
standards for how the Internet and many other related technologies
|
|
interrelate and interoperate.
|
|
|
|
VLAN
|
|
An acronym for "Virtual Local Area Network"; a single physical switch
|
|
can be divided into multiple "virtual" switches via the configuration
|
|
of VLANs, and assigning individual switchports into a given VLAN.
|
|
Each VLAN represents a Ethernet broadcast domain (boundary); best
|
|
practices dictate that a single IP (Layer 3) network be mapped to a
|
|
single VLAN. Packets must be routed between VLANs (either by an
|
|
outboard router, or by an internal router in what is known as a
|
|
"Layer 3 switch.")
