building. 10BaseT Ethernet is the most commonly used form of LAN. A piece of hardware called a hub
serves as the common wiring point, enabling data to be sent from one machine to another over the
network. LANs are typically limited to distances of less than 500 meters and provide low-cost, high-
bandwidth networking capabilities within a small geographical area.
MODEM (Modulator-Demodulator)
A modem is an external box or internal circuitry that converts computer data into sound that can be
transmitted over phone lines. First used to send telegrams, early modems alternated between two
different tones. This is called
modulation, and the process of modulating (and demodulating at the
receiving end) gave the modem its name.
NAT (Network Address Translation)
Network address translation is a scheme that allows two connected networks to use different and
incompatible IP addressing schemes. Address translation allows hosts on a private internal network to
transparently communicate with destinations on an external network or vice versa. NAT also refers to
the name of a device that performs these functions. It enables certain TCP/IP application to be used
by converting the communication protocol of the applicative layer or transport layer.
NetBEUI (NetBIOS Extended User Interface)
NetBEUI is an extended version of NetBIOS that connects clients in a LAN environment. IBM
developed this standard protocol, which is a set of rules that an operating system uses to control how
computers on a network to talk to each other. The protocol is also used by Microsoft and Novell on
many network operating systems including LAN Server, LAN Manager, Windows NT, and Windows 95.
NetBIOS (Network Basic input/output System)
Application Program Interface used in PC-LAN provided by IBM and Microsoft and it also works as a
protocol for local area network. ‘NetBEUI(NetBIOS extended user interface)’ is the extended version
of initial release. It is a basic format for Windows network environment in which NetBIOS name is
added to personal computer to be networked.
POP3 (Post Office Protocol Ver.3)
The current champ in Internet email mailbox access standards, but its limitations-basically, you
connect to a server and download all your messages, which are then deleted from the server-
discourage flexibility. Of course, some clients let you leave all messages on the server, and/or refuse
to download messages above a certain size. The current version of POP is POP3
RFC (Request For Comments)
Public documents series announced by IAB for Internet-based inspection, suggetion, technologies,
and opinion. It is used as principle means for announcing the information on the Internet such as
procedure or format necessary when actualizing network protocol or service.
