ACL

Access Control List

A list that controls the access to an object

API

Application Programming Interface

An API is an interface through which programsinteract with each other, normally through DLL calls.

BDC

Backup Domain Controller

An NT Server machine that receives a copy of themaster user-database from the PDC and can validate logons

COLD

Computer Output to Laser Disk

DAP

Directory Access Protocol

Used to access a directory service

DHCP

Dynamic Host Configuration Protocol

A service that automatically assigns IP-addressesto clients from a given range (scope)

DLC

DSA

Directory System Agent

The name of a domain controller, e.g. titanic

DSA UUID

DSA Universally Unique ID

The 128 bit number used to identify objects storedin the directory.

FAT

The DOS way of organizing a harddisk

Lots ofwasted space on large disks

Little file security

GUID

Globally Unique IDentifier

A 64-bit number that is statistically unique

HPFS

High Performance File System

The OS/2 way of organizing a harddisk

ICMP

Internet Contol Message Protocol

Internet Control Message Protocol (ICMP) is amaintenance protocol specified in RFC 792 and is normally considered to be partof the IP layer. ICMP messages are encapsulated within IP datagrams, so theycan be routed throughout an internetwork. ICMP is used by Windows NT to:Build and maintain route tables.Assist in Path Maximum Transfer Unit (PMTU) discovery.Diagnose problems (using the utilities ping and tracert).Adjust flow control to prevent link or router saturation.

IPX/SPX

Internetwork Packet Exchange / Sequenced PacketExchange

Novell NetWare protocol

Based onthe Xerox protocol XNS(Xerox Networking Services)

LDAP

Lightweight Directory Access Protocol

Protocol used to query a directory service

MAC-addresses

Media Access Control layer addresses

48-bit address that is hardwired into the netcard

DHCP, among others, use this to identify a machine requesting a certainIP-address within its lease duration

NBT

NetBIOS over TCP/IP

NetBIOS built on top of the TCP/IP suite

NDIS

Network Driver Interface Specification

Microsoft binding standard (interface betweennetcard driver and protocol)

Can load into high memory on DOS systems

NetBEUI

NetBIOS Extended User Interface

The actual NetBIOS transport protocol

NetBIOS

Network Basic Input/Output System

An API of 18 networking-related commands

NIC

Network Interface Card

Such as an ethernet card. Also you have InterNIC,the organization that assigns domain names and IP-addresses to Internet hosts,http://www.internic.net

NTFS

New Technology File System

The NT way of organizing a harddisk

Efficient storage

High level of security

ODI

Open Data-link Interface

Novell binding standard (interface between netcarddriver and protocol)

Can not load into high memory on DOS systems

PDC

Primary Domain Controller

The NT Server machine that stores the masteruser-database in a domain

RAID

Redundant Array of Inexpensive Drives

A number of disks with data distributed all overthem to allow for faster access

Can also provide data-recoverability

NT supports RAID level 0,1 and 5

RIP

Routing Information Protocol

The protocol that takes care of routing on theInternet

SID number

Security IDentification number

Every object in an NT domain have a SID number

Reinstalling will not give the same SID number

SPS

Standby Power Supply

Device that is installed between the wall outletand the computer inlet

The power goes directly into the computer with abranch to the batteries

When the power fail, the batteries take over, but with a delay

The delay should be 4 ms or better for proper operation

TCP/IP

Transmission Control Protocol / Internet Protocol

The protocol used for Inter- and Intranetcommunications

UDP

User Datagram Protocol

A basic alternative to TCP for IP communication

Among other things, UDP is used for communicating withDHCP-servers

UPS

Uninterruptible Power Supply

Device that is installed between the wall outletand the computer inlet

The power is directed through the batteries, thusstabilizing the variance of the power from the outlet

Because of this, the switch delay is 0 ms

WINS

Windows Internet Naming Service
