Client/server: network architecture in which one computer or program (the client) makes a service request from
another computer or program (the host 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: computing services provided over Internet in 3 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 that work 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 original programming language used to specify the formatting of a
webpage. The current version is HTML5, which provides significantly enhanced graphics capabilities.
Infrastructure: hardware, software, and protocols that support telecommunications.
Internet2: research and development consortium 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 AT&T, Sprint, T-Mobile, and
Verizon - the same companies and networks that provide cellular and landline phone services.
Internet service provider (ISP). A company that provides individuals and organizations with access to the Internet.
More than 10,000 local, regional, and national providers exist around the world.
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): network that connects users with computer resources in region or geographic
area larger than that covered by a large local area network but smaller than 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 transponders in tags that can be attached to merchandise or other
objects and read wirelessly using an RFID reader, used 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.
Really Simple Syndication (RSS): web technology used to automatically deliver frequently updated web content.
Router: a network device that manages network traffic by evaluating messages and routing them over the fastest
path to their destination. The majority of these hardware devices are manufactured by Cisco.
Transmission Control Protocol (TCP) and Internet Protocol (IP): The protocol on which the Internet is based.
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: carries signal and creates an interface between a sending device and 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 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.
Wi-Fi (Wireless Fidelity) use the IEEE 802.11 family of standards for wireless networking technology that uses
access points to wirelessly connect users to networks within a range of 250–1000 feet (75–300 meters).
Worldwide Interoperability for Microwave Access (WiMAX): 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.
