F
Fast Ethernet - A new Ethernet standard that supports 100 Mbps using category 5 twisted pair or fiber optic
cable.
Fiber Optic Cable - A cable, consisting of a center glass core surrounded by layers of plastic, that transmits
data using light rather than electricity. It has the ability to carry more information over much longer distances.
File Server - A computer connected to the network that contains primary files/applications and shares them as
requested with the other computers on the network. If the file server is dedicated for that purpose only, it is
connected to a client/server network. An example of a client/server network is Novell Netware. All the
computers connected to a peer-to-peer network are capable of being the file server. Two examples of peer-to-
peer networks are LANtastic and Windows for Workgroups.
G
Gigabit Ethernet - An Ethernet protocol that raises the transmission rates to 1 Gbps (gigabits per second). It
is primarily used for a high speed backbone of a network.
H
Hub - A hardware device that contains multiple independent but connected modules of network and
internetwork equipment. Hubs can be active (where they repeat signals sent through them) or passive (where
they do not repeat but merely split signals sent through them).
I
Infrared - Electromagnetic waves whose frequency range is above that of microwaves, but below that of the
visible spectrum.
Intranet - Network internal to an organization that uses Internet protocols.
Internet - A global network of networks used to exchange information using the TCP/IP protocol. It allows for
electronic mail and the accessing ad retrieval of information from remote sources.
ISP (Internet Service Provider) - Company that provide access to internet
L
LAN (Local Area Network) - A network connecting computers in a relatively small area such as a building.
Linear Bus - A network topology in which each node attaches directly to a common cable.
LocalTalk - Apple Corporation proprietary protocol that uses CSMA/CA media access scheme and supports
transmissions at speeds of 230 Kbps (Kilobits per second).
M
MAN (Metropolitan Area Network) - A network connecting computers over a large geographical area, such as
a city or school district.
Modem (Modulator/Demodulator) - Devices that convert digital and analog signals. Modems allow computer
data (digital) to be transmitted over voice-grade telephone lines (analog).
Multiplexer - A device that allows multiple logical signals to be transmitted simultaneously across a single
physical channel.
Network Modem - A modem connected to a Local Area Network (LAN) that is accessible from any
workstation on the network.
Network Interface Card (NIC) - A board that provides network communication capabilities to and from a
computer.
