Bluetooth: enables digital devices to communicate directly with each other wirelessly over short distances.
Cascading Style Sheets (CSS): allows easy application of visual styles for fonts, colors, layouts, and other page
attributes to create visual themes for webpages and sites.
Cellular Network: radio network in which a geographic area is divided into cells with a transceiver antenna (tower)
and station at the center of each cell, to support wireless mobile communications
Client/server: network architecture in which one computer or program (the client) makes a service request from
another computer or program (the server), which provides the service.
Cloud Computing: delivers a variety of computing resources from the Internet as a service for free or for a fee, to
relieve users from the burden of installing, maintaining, and securing those resources themselves.
Cloud Services include computing services provided over the Internet in three categories: infrastructure, platform,
and software.
Computer network: a collection of computing devices connected together to share resources such
as files, software, processors, storage, printers, and Internet connections.
Cookie: sometimes called an HTTP cookie, this is a small text file placed on a user’s computer by a web server in
order to identify the user whenever he or she returns to visit a website.
Domain Name System (DNS) maintains a database of all domain names and IP addresses used on the Internet and
acts like a phonebook, supplying information to Internet nodes and routers working to get data packets to their
destination
Extensible Markup Language (XML): provides a method for describing and classifying Internet-delivered data so
that it is easier to organize and manage.
Hypertext Markup Language (HTML) is the main markup language used to specify the formatting of a webpage.
Infrastructure: hardware, software, and protocols that support telecommunications.
Internet2 research and development consortium led by more than 200 U.S. universities and supported by
partnerships with industry and government to develop and deploy advanced network applications and technologies
for tomorrow’s Internet.
Internet backbone: main Internet pathways and connections, made up of the many national and international
communication networks that are owned by major telecom companies such as Verizon, AT&T, and Sprint—the
same companies and networks that provide telephone service.
Internet service provider (ISP). A company that provides individuals and organizations with access to the Internet.
Local area network (LAN) is a privately owned computer network that connects PCs, servers, printers, and other
devices within a facility or local geographic area.
Long Term Evolution (LTE): fourth-generation wireless broadband technology that was developed to allow GSM
cellular technology to evolve to provide very high-speed Internet access
Metropolitan area network (MAN): a network that interconnects users with computer resources in a region
or geographic area larger than that covered by even a large local area network (LAN) but smaller than the area
covered by a wide area network
Peer-to-peer (P2P): a network architecture that does not utilize a central server but facilitates communication
directly between clients with computers acting as both client and server.
Personal area network (PAN): the interconnection of personal information technology devices, typically
wirelessly, within the range of an individual.
Plug-in: also called an extension or add-on, this works with a web browser to offer extended services such as audio
players, video, animation, 3D graphics viewers, and interactive media.
Port: an address used by clients and servers that is associated with a specific service.
Radio Frequency Identification (RFID): uses tiny transponders in tags that can be attached to merchandise or
other objects and read wirelessly using an RFID reader, typically for inventory and supply chain management or to
facilitate commercial transactions
Radio Spectrum: all of the frequencies available for radio waves from 10 KHz to 300 GHz and their assigned uses.

content, such as blogs, podcasts, and news, in a standardized fashion
Router: a network device that manages network traffic by evaluating messages and routing them over the fastest
path to their destination.

Telecommunication: electronic transmission and reception of signals for voice and data communications
Telecommunication devices: computer hardware designed to support telecommunications activities for individuals
and businesses
Telecommunications media: anything that carries a signal and creates an interface between a sending device and a
receiving device.
Telecommunication signals: analog or digital electronic transmissions for the purpose of communication.
Telecommunications software: software based on telecommunications protocols used to control, monitor, and
troubleshoot data traveling over a telecommunications network
Uniform Resource Locator (URL): acts as a webpage address, incorporating the domain name of the web server
and the location of the webpage file on the server.
Voice over IP (VoIP): technologies that support voice communications using Internet Protocol over data networks
Web development software allows developers to create webpages more easily using a word-processing-style
environment and automating complex coding activities
Web portal: a webpage that combines useful information and links, and acts as an entry point to the web—the first
page you open when you begin browsing the web at home or at work.
Web server: software that fulfills webpage requests from web clients and to the computers that run such software.
Wide area network (WAN) connects LANs and MANs between cities, across countries, and around the world,
using microwave and satellite transmission or telephone lines.
WiMAX, which stands for Worldwide Interoperability for Microwave Access, also known as IEEE 802.16, is a
fourth-generation wireless broadband technology that evolved from Wi-Fi to provide faster Internet access at a
longer range.
Wireless data communications: telecommunications that take place over the air for data and Internet access.
