This wheel diagram sample was created on the base of figure illustrating the webpage "Chapter 3: Current State of the Ecosystem" of the website of the National Broadband Plan of US Federal Communications Comission (FCC). "The broadband ecosystem includes applications and content: e-mail, search, news, maps, sales and marketing applications used by businesses, user-generated video and hundreds of thousands of more specialized uses. Ultimately, the value of broadband is realized when it delivers useful applications and content to end-users.
Applications run on devices that attach to the network and allow users to communicate: computers, smartphones, set-top boxes, e-book readers, sensors, private branch exchanges (PBX), local area network routers, modems and an ever-growing list of other devices. New devices mean new opportunities for applications and content.
Finally, broadband networks can take multiple forms: wired or wireless, fixed or mobile, terrestrial or satellite. Different types of networks have different capabilities, benefits and costs.
The value of being connected to the network increases as more people and businesses choose to adopt broadband and use applications and devices that the network supports. Several factors contribute to their decisions. These include whether they can afford a connection, whether they are comfortable with digital technology and whether they believe broadband is useful.
Networks, devices and applications drive each other in a virtuous cycle. If networks are fast, reliable and widely available, companies produce more powerful, more capable devices to connect to those networks. These devices, in turn, encourage innovators and entrepreneurs to develop exciting applications and content. These new applications draw interest among end-users, bring new users online and increase use among those who already subscribe to broadband services. This growth in the broadband ecosystem reinforces the cycle, encouraging service providers to boost the speed, functionality and reach of their networks."

"A call centre or call center is a centralised office used for the purpose of receiving or transmitting a large volume of requests by telephone. An inbound call centre is operated by a company to administer incoming product support or information inquiries from consumers. Outbound call centers are operated for telemarketing, solicitation of charitable or political donations, debt collection and market research. In addition to a call centre, collective handling of letter, fax, live support software,social media and e-mail at one location is known as a contact centre.
A call centre is operated through an extensive open workspace for call centre agents, with work stations that include a computer for each agent, a telephone set or headset connected to a telecom switch, and one or more supervisor stations. It can be independently operated or networked with additional centres, often linked to a corporate computer network, including mainframes, microcomputers and LANs. Increasingly, the voice and data pathways into the centre are linked through a set of new technologies called computer telephony integration (CTI)." [Call centre. Wikipedia]
