ARP

Acronym for Address Resolution Protocol, which is a method for finding a host's Ethernet address from its Internet address.

ASCII

Acronym for American Standard Code for Information Interchange, which is a code representation used for displaying or printing letters, numbers, and other characters.

BIOS

Acronym for basic input/output system, which is the part of system software that provides the lowest-level interface to peripheral devices and which controls the first stage of the system boot process, including installation of the operating system into memory.

BMC

Abbreviation for baseboard management controller, which is the interface between the ERA/MC controller and the managed system's ESM.

bus

A set of conductors connecting the various functional units in a computer. Busses are named by the type of data they carry, such as data bus, address bus, or PCI bus.

CD

Abbreviation for compact disc.

CHAP

Acronym for Challenge-Handshake Authentication Protocol, which is an authentication method used by PPP servers to validate the identity of the originator of the connection.

CLI

Abbreviation for command-line interface.

console redirection

Console redirection is a function that directs a managed system's display screen, mouse functions, and keyboard functions to the corresponding devices on a management station. You may then use the management station's system console to control the managed system.

DHCP

Abbreviation for Dynamic Host Configuration Protocol, which is a protocol that provides a means to dynamically allocate IP addresses to computers on a local area network.

ERA/MC

Abbreviation for Embedded Remote Access/MC.

ESM

Abbreviation for embedded systems management, which is a set of instruction coding in system software and firmware that notifies a user about potential hardware problems on your system.

GMT

Abbreviation for Greenwich Mean Time, which is the standard time common to every place in the world. GMT nominally reflects the mean solar time along the prime meridian (0 longitude) that runs through the Greenwich Observatory outside of London, UK.

GPIO

Abbreviation for general purpose input/output.

GUI

Abbreviation for graphical user interface, which refers to a computer display interface that uses elements such as windows, dialog boxes, and buttons as opposed to a command prompt interface, in which all user interaction is displayed and typed in text.

hardware log

Records events generated by the ERA/MC controller and ESM.

ID

Abbreviation for identifier, commonly used when referring to a user identifier (user ID) or object identifier (object ID).

IP

Abbreviation for Internet Protocol, which is the network layer for TCP/IP. IP provides packet routing, fragmentation, and reassembly.

IPMB

Abbreviation for intelligent platform management bus, which is a bus used in systems management technology.

IPMI

Abbreviation for Intelligent Platform Management Interface, which is a part of systems management technology.

Kbps

Abbreviation for kilobits per second, which is a data transfer rate.

KVM

Abbreviation for Keyboard, Video, Mouse, switch. A hardware device that enables a single keyboard, video monitor and mouse to control more than one system one at a time.

LAN

Abbreviation for local area network.

LED

Abbreviation for light-emitting diode.

MAC

Acronym for media access control, which is a network sublayer between a network node and the network physical layer.

MAC address

Acronym for media access control address, which is a unique address embedded in the physical components of a NIC.

Mbps

Abbreviation for megabits per second, which is a data transfer rate.

MIB

Abbreviation for management information base.

NIC

Acronym for network interface controller, which is an adapter circuit board installed in a computer to provide a physical connection to a network.

PAP

Acronym for Password Authentication Protocol. A form of authentication, in which a user's name and password are transmitted over a network and compared to a table of name-password pairs.

PPP

Abbreviation for Point-to-Point Protocol. A protocol for communication between two computers using a serial interface, typically a personal computer connected by phone line to a server.

RAC

Abbreviation for remote access controller.

RAM

Acronym for random-access memory. RAM is general-purpose readable and writable memory on systems and a RAC.

RAM disk

A memory-resident program which emulates a hard drive. A RAC maintains a RAM disk in its memory.

ROM

Acronym for read-only memory, which is memory from which data may be read, but to which data cannot be written.

SMI

Abbreviation for systems management interrupt.

SMTP

Abbreviation for Simple Mail Transfer Protocol, which is a protocol used to transfer electronic mail between systems, usually over an Ethernet.

SNMP

Abbreviation for Simple Network Management Protocol, which is a protocol designed to manage nodes on an IP network. The controller is an SNMP-managed device (node).

SNMP trap

A notification (event) generated by the controller or ESM that contains information about state changes on the managed system or about potential hardware problems.

TAP

Abbreviation for Telelocator Alphanumeric Protocol. A text messaging protocol for serial and dialup connections.

TCP/IP

Abbreviation for Transmission Control Protocol/Internet Protocol, which represents the set of standard Ethernet protocols that includes the network layer and transport layer protocols.

TFTP

Abbreviation for Trivial File Transfer Protocol, which is a simple file transfer protocol used for downloading boot code to diskless devices or systems.

UPS

Abbreviation for uninterruptible power supply.

UTC

Abbreviation for Universal Coordinated Time. See GMT.

VNC

Abbreviation for virtual network computing.

VT-100

Abbreviation for Video Terminal 100, which is used by the most common terminal emulation programs.

WAN

Abbreviation for wide area network.
