Network
A collection of computers and devices connected together via communications devices and transmission media.
LAN
A local area network (LAN) is a network that connects computers and devices in a limited geographical area such as a home, school computer labora- tory, office building, or closely positioned group of buildings.
MAN
A metropolitan area network (MAN) is a high-speed network that connects local area networks in a metropolitan area such as a city or town and handles the bulk of communications activity across that region.
CLIENT/SERVER Network
A network architecture in which one or more computers act as a server.

Receiving Device
Accepts the transmission of data, instructions, or information.
Wikis
Collaborative Web sites that allow users to create, add to, modify, or delete Web site content
Peer Network
Computer can function as both a server and a client. This kind of network is represented by a two-way relationship, a give and take among equals or peers.
VoIP
Conversation that takes place over the Internet using a telephone connected to a computer or mobile device or telephone adapter
802.11 (WI-FI)
Developed by IEEE, 802.11 also known as Wi-Fi (wireless fidelity) and wireless Ethernet, is a series of network standards that specifies how two wireless devices communicate over the air with each other.
Family Network
Everyone contributes no matter how big or small.
Network Standard
Guidelines that specify the way computers access the medium to which they are connected, the type(s) of medium used, the speeds used on different types of networks, and the type(s) of physical cable and/or the wireless technology used.
IRDA
Infrared Data Association Some computers and devices use the IrDA specification to transmit data wirelessly to each other via infrared (IR) light waves.
FTP
Internet standard that permits users to upload and download files to and from FTP servers on the Internet
Web Folders
Location on a Web server (also known as an HTTP server) to which users publish documents and other files
Newsgroups
Online areas in which users have written discussions about a particular subject
WAP
Wireless Application Protocol (WAP) is a standard, specifically a protocol, that specifies how some mobile devices such as smart phones can display the content of Internet services such as the Web, e-mail, and chat rooms.
video conferencing
Real-time meeting between two or more geographically separated people who use a network to transmit audio and video data
Instant Messaging
Real-time one-on-one communications service on the Internet that notifies you when one or more people are online and then allows you to exchange messages, pictures, files, audio, and video
Chat Rooms
Real-time typed conversation among two or more people that takes place on a computer connected to a network that also may allow the exchange of messages, pictures, files, audio, and video
RSS
Specification that enables Web content to be distributed to subscribers
Local Computer
The computer to which you have physical access. 1st Computer on a network.
Blogs
Time-stamped articles on a network that reflect the author's interests, opinions, and personality
TCP/IP
Transmission Control Protocol/Internet Protocol is a network standard, specifically a protocol, that defines how messages (data) are routed from one end of a network to the other.
Transmission of messages and files via a computer network
Fax Machine
Transmits and receives documents over telephone lines
Web
Worldwide collection of electronic documents on the Internet that users access through a Web browser
Internet
Worldwide collection of networks that links millions of businesses, government agencies, educational institutions, and individuals
Sending Device
a device that initiates an instruction to transmit data, instructions, or information
Ethernet
a network standard that specifies no central computer or device on the network (nodes) should control when data can be transmitted; that is, each node attempts to trans- mit data when it determines the network is able to receive communications.
Server
a physical computer dedicated to run services to serve the needs of other computers.
Computer Communications
a process in which two or more computers or devices transfer data, instructions, and information
STAR Network
all of the computers and devices (nodes) on the network connect to a central device, thus forming a star.
Text Messaging
also called SMS (short message service), capability allows users to send and receive short text messages on a phone or other mobile device
Clients
are other computers and mobile devices on the network that rely on the server for its resources
BUS Network
consists of a single central cable, to which all computers and other devices connect.
Server
controls access to the hardware, software, and other resources on the net- work and provides a centralized storage area for programs, data, and information
P2P
describes an Internet network, on which users access each other's hard disks and exchange files directly
Bi-directional
functioning in two directions
Client
is a computer hardware device or software that accesses a service made available by a server.
Bluetooth
is a standard, specifically a protocol, that defines how two Bluetooth devices use short-range radio waves to transmit data.
Intranet
is an internal network that uses Internet technolo- gies.
Network Topology
refers to the layout of the computers and devices in a communica- tions network.
Peer-to-Peer Network
simple, inexpensive network that typically connects fewer than 10 com- puters
Token Ring
standard specifies that computers and devices on the network share or pass a special signal, called a token, in a unidirectional manner and in a preset order
Communications Channel
transmission media on which the data, instructions, or information travel.
Computer Network
two or more computers communicating
UWB
ultra-wideband, is a network standard that specifies how two UWB devices use short-range radio waves to communicate at high speeds with each other. For optimal com- munications, the devices should be within 2 to 10 meters (about 6.5 to 33 feet) of each other.
