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.
Network - A system that transmits any combination of voice, video, and/or data
between users.
Network Mask - also known as the “Subnet Mask.”
NIC ( N etwork I nterface C ard) - A board installed in a computer system, usually a PC,
to provide network communication capabilities to and from that computer system. Also
called an adapter.
Notebook (PC) - A notebook computer is a battery-powered personal computer
generally smaller than a briefcase that can easily be transported and conveniently used
in temporary spaces such as on airplanes, in libraries, at temporary offices, and at
meetings. A notebook computer, sometimes called a laptop computer, typically weighs
less than five pounds and is three inches or less in thickness.
Packet Filtering - Discarding unwanted network traffic based on its originating
address or range of addresses or its type (e-mail, file transfer, etc.).
Partitioning - To divide a resource or application into smaller pieces.
PCI ( P eripheral C omponent I nterconnect) - A peripheral bus commonly used in PCs,
Macintoshes and workstations. It was designed primarily by Intel and first appeared on
PCs in late 1993. PCI provides a high-speed data path between the CPU and peripheral
devices (video, disk, network, etc.). There are typically three or four PCI slots on the
motherboard. In a Pentium PC, there is generally a mix of PCI and ISA slots or PCI
and EISA slots. Early on, the PCI bus was known as a “local bus.”
PCI provides “plug and play” capability, automatically configuring the PCI cards at
startup. When PCI is used with the ISA bus, the only thing that is generally required is
to indicate in the CMOS memory, which IRQs are already in use by ISA cards. PCI
takes care of the rest.
PCI allows IRQs to be shared, which helps to solve the problem of limited IRQs
available on a PC. For example, if there were only one IRQ left over after ISA devices
were given their required IRQs, all PCI devices could share it. In a PCI-only machine,
there cannot be insufficient IRQs, as all can be shared.
PCMCIA - The PCMCIA (Personal Computer Memory Card International
Association) is an industry group organized in 1989 to promote standards for a credit
card-size memory or I/O device that would fit into a personal computer, usually a
notebook or laptop computer.
Ping ( P acket IN ternet G roper) - An Internet utility used to determine whether a
particular IP address is online. It is used to test and debug a network by sending out a
packet and waiting for a response.
Plug-and-Play - The ability of a computer system to configure expansion boards and
other devices automatically without requiring the user to turn off the system during
installation.
