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 - IPSec (Internet Protocol Security) is a developing standard for security at the network or packet processing layer of network communication. A big advantage of IPSec is that security arrangements can be handled without requir- ing changes to individual user computers.
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.
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 number assigned by the manufacturer to any Ethernet networking device, such as a net- work 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.
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.
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.
EtherFast® Cable/DSL Routers
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 session 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 protocols.
NetBIOS computers are identified by a unique
There are two NetBIOS modes. The Datagram mode is the fastest mode, but does not guarantee delivery. It uses a
Network - A system that transmits any combination of voice, video, and/or data between users.
Network Mask - also known as the “Subnet Mask.”
NIC (Network Interface Card) - A board installed in a computer system, usual- ly a PC, to provide network communication capabilities to and from that com- puter system. Also called an adapter.
Notebook (PC) - A notebook computer is a
Packet Filtering - Discarding unwanted network traffic based on its originating address or range of addresses or its type
