 Virtualization 

Technology (Intel

®

 VT)

Processor virtualization which when used in conjunction with the Virtual Machine Monitor software 

enables multiple, robust independent software environments inside a single platform.

Integrated Heat Spreader 

(IHS)

A component of the processor package used to enhance the thermal performance of the package. 

Component thermal solutions interface with the processor at the IHS surface.

ISI

The effect of a previous signal (or transition) on the interconnect delay. For example, when a signal 

is transmitted down a line and the reflections due to the transition have not completely dissipated, 

the following data transition launched onto the bus is affected. Interconnect Symbolic Interference 

(ISI) is dependent upon frequency, time delay of the line, and the reflection coefficient at the driver 

and receiver. ISI impacts both timing and signal integrity.

Jitter

Any timing variation of a transition edge or edges from the defined Unit Interval (UI).

LAN (Auxiliary Power-Up)

If connecting the LAN controller to a power source (occurs even before system power-up).

Land

The contact point of a processor in the 559–Ball BGA package.

LCD

Name for the external LAN Connected Device, sometimes also called a PHY device. The LCD name 

distinguishes between the whole device and the PHY portion within the LCD.

LCI

LAN Connect Interface

LLC

Last Level Cache

LLDP

Link Layer Discovery Protocol defined in IEEE 802.1AB and used by IEEE 802.3az (EEE) for system 

wake time negotiation.

LOM

LAN on Motherboard

LPC

Low Pin Count

LPI

Low-Power Idle is the low-power state of Ethernet link as defined in IEEE 802.3az.

LRU

Least Recently Used. A term used in conjunction with cache hierarchy.

LS

Low-speed. Refers to USB.

LSO

Large Send Offload

LTR

Latency Tolerance Reporting (PCI Express* (PCIe*) protocol)

LVR

Linear Voltage Regulator

MAC

Media Access Control

MC

Management Controller

MCTP

DMTF Management Component Transport Protocol (MCTP) specification. A transport protocol to 

allow communication between a management controller and controlled device over various 

transports.

MDIO

Management Data Input/Output Interface over MDC/MDIO lines

MIFS/MIPG

Minimum Inter-Frame Spacing/Minimum Inter-Packet Gap

MLC

Mid-Level Cache

MMC

Multi-Node Management Controller

MMW

Maximum Memory Window

MPS

Maximum Payload Size in PCIe specification

MSS

Maximum Segment Size. Largest amount of data, in a packet (without headers) that can be 

transmitted. Specified in bytes.

MTU

Maximum Transmit Unit. Largest packet size (headers and data) that can be transmitted. Specified 

in bytes.

NC Network 

Controller

NC-SI

Network Controller Sideband Interface DMTF Specification

Network

The trace of a Printed Circuit Board (PCB) that completes an electrical connection between two or 

more components.

NIC

Network Interface Controller
