than one is required) and sends it to the IP address that is obtained by looking up the domain name in the Uniform Resource Locator you requested or in the
IPCONFIG - A utility that provides for querying, defining and managing IP addresses within a network. A commonly used utility, under Windows NT and 2000, for configuring networks with static IP addresses.
IPSec (Internet Protocol Security) - A suite of protocols used to implement secure exchange of packets at the IP layer. IPSec supports two basic modes: Transport and Tunnel. Transport encrypts the payload of each packet, leaving the header untouched, while Tunnel mode encrypts both the header and the pay- load and is therefore more secure. IPSec must be supported on both transmit- ter and receiver and must share a public key. Tunnel mode is widely deployed in VPNs (Virtual Private Networks).
IRQ (Interrupt ReQuest) - A hardware interrupt on a PC. There are 16 IRQ lines used to signal the CPU that a peripheral event has started or terminated. Except for PCI devices, two devices cannot use the same line.
ISM band - The FCC and their counterparts outside of the U.S. have set aside bandwidth for unlicensed use in the ISM (Industrial, Scientific and Medical) band. Spectrum in the vicinity of 2.4 GHz, in particular, is being made avail- able worldwide. This presents a truly revolutionary opportunity to place con- venient
ISP - An ISP (Internet service provider) is a company that provides individuals and companies access to the Internet and other related services such as website building and virtual hosting.
LAN - A local area network (LAN) is a group of computers and associated devices that share a common communications line and typically share the resources of a single processor or server within a small geographic area (for example, within an office building).
Latency - The time delay between when the first bit of a packet is received and the last bit is forwarded.
MAC Address - The MAC (Media Access Control) address is a unique num- ber assigned by the manufacturer to any Ethernet networking device, such as a network adapter, that allows the network to identify it at the hardware level.
Mbps (MegaBits Per Second) - One million bits per second; unit of measure- ment for data transmission.
MD5 - A type of
MDI (Medium Dependent Interface) - On a network hub or switch, a MDI port, also known as an uplink port, connects to another hub or switch using a
MDIX (Medium Dependent Interface Crossed) - On a network hub or switch, a MDIX port connects to a computer using a
mIRC - mIRC runs under Windows and provides a graphical interface for log- ging onto IRC servers and listing, joining, and leaving channels.
Motherboard - A motherboard is the physical arrangement in a computer that contains the computer’s basic circuitry and components.
Multicasting - Sending data to a group of nodes instead of a single destination.
NAT - NAT (Network Address Translation) is the translation of an Internet Protocol address (IP address) used within one network to a different IP address known within another network. One network is designated the inside network and the other is the outside.
NetBEUI (NetBIOS Extended User Interface) - The transport layer for NetBIOS. NetBIOS and NetBEUI were originally part of a single protocol suite that was later separated. NetBIOS sessions can be transported over NetBEUI, TCP/IP, and SPX/IPX protocols.
NetBIOS - The native networking protocol in DOS and Windows networks. Although originally combined with its transport layer protocol (NetBEUI), NetBIOS today provides a programming interface for applications at the ses- sion layer (layer 5). NetBIOS can ride over NetBEUI, its native transport, which is not routable, or over TCP/IP and IPX/SPX, which are routable proto- cols.
