Domain - A subnetwork comprised of a group of clients and servers under the
control of one security database. Dividing LANs into domains improves
performance and security.
Ethernet - IEEE standard network protocol that specifies how data is placed
on and retrieved from a common transmission medium. Has a transfer rate of
10 Mbps. Forms the underlying transport vehicle used by several upper-level
protocols, including TCP/IP and XNS.
Fast Ethernet - A 100 Mbps technology based on the 10Base-T Ethernet
CSMA/CD network access method.
Hardware
-
Hardware
is
telecommunications, and other information technology devices. The term arose
as a way to distinguish the "box" and the electronic circuitry and components
of a computer from the program you put in it to make it do things. The program
came to be known as the software.
Hot Swap - The ability to replace a card or other hardware part in a hardware
device without turning it off or losing functionality.
Hub - The device that serves as the central location for attaching wires from
workstations. Can be passive, where there is no amplification of the signals; or
active, where the hubs are used like repeaters to provide an extension of the
cable that connects to a workstation.
IEEE - The Institute of Electrical and Electronics Engineers. The IEEE
describes itself as "the world's largest technical professional society—
promoting the development and application of electrotechnology and allied
sciences for the benefit of humanity, the advancement of the profession, and
the well-being of our members."
The IEEE fosters the development of standards that often become national and
international standards. The organization publishes a number of journals, has
many local chapters, and several large societies in special areas, such as the
IEEE Computer Society.
IP Address - In the most widely installed level of the Internet Protocol (IP)
today, an IP address is a 32-binary digit number that identifies each sender or
receiver of information that is sent in packet across the Internet. When you
request an HTML page or send e-mail, the Internet Protocol part of TCP/IP
includes your IP address in the message (actually, in each of the packets if more

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
e-mail address you're sending a note to. At the other end, the recipient can see
the IP address of the Web page requester or the e-mail sender and can respond
by sending another message using the IP address it received.
IPCONFIG - A Windows NT or 2000 utility that provides for querying,
defining and managing IP addresses within a network.
L A N - 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).
Mbps (MegaBits Per Second) - One million bits per second; unit of
measurement for data transmission.
Motherboard - A motherboard is the physical arrangement in a computer that
contains the computer's basic circuitry and components.
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 IPX/SPX 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 15-character name, and
Windows machines (NetBIOS machines) periodically broadcast their names
over the network so that Network Neighborhood can catalog them. For TCP/IP
networks, NetBIOS names are turned into IP addresses via manual
configuration in an LMHOSTS file or a WINS server.
There are two NetBIOS modes. The Datagram mode is the fastest mode, but
does not guarantee delivery. It uses a self-contained packet with send and
receive name, usually limited to 512 bytes. If the recipient device is not
listening for messages, the datagram is lost. The Session mode establishes a
connection until broken. It guarantees delivery of messages up to 64KB long.
