Network Hubs

"Star networks are one of the most common computer network topologies. In its simplest form, a star network consists of one central switch, hub or computer, which act as a conduit to transmit messages. This consists of a central node, to which all other nodes are connected; this central node provides a common connection point for all nodes through a hub. In star topology, every node (computer workstation or any other peripheral) is connected to a central node called a hub or switch. The switch is the server and the peripherals are the clients. Thus, the hub and leaf nodes, and the transmission lines between them, form a graph with the topology of a star." [Star network. Wikipedia]

This circle-spoke diagram sample shows the social determinants of health. It was created on the base of the hub-and-spoke diagram from the Health Canada website. [hc-sc.gc.ca/ sr-sr/ pubs/ hpr-rpms/ bull/ 2005-climat/ 2005-climat-6-eng.php]
"Social determinants of health are the economic and social conditions – and their distribution among the population – that influence individual and group differences in health status. They are risk factors found in one's living and working conditions (such as the distribution of income, wealth, influence, and power), rather than individual factors (such as behavioural risk factors or genetics) that influence the risk for a disease, or vulnerability to disease or injury. According to some viewpoints, these distributions of social determinants are shaped by public policies that reflect the influence of prevailing political ideologies of those governing a jurisdiction. ...
In 2003, the World Health Organization (WHO) Europe suggested that the social determinants of health included:
(1) Social gradients (life expectancy is shorter and disease is more common further down the social ladder).
(2) Stress (including stress in the workplace).
(3) Early childhood development.
(4) Social exclusion.
(5) Unemployment.
(6) Social support networks.
(7) Addiction.
(8) Availability of healthy food.
(9) Availability of healthy transportation." [Social determinants of health. Wikipedia]

"A computer network or data network is a telecommunications network that allows computers to exchange data. In computer networks, networked computing devices (network nodes) pass data to each other along data connections. The connections (network links) between nodes are established using either cable media or wireless media. The best-known computer network is the Internet.
Network devices that originate, route and terminate the data are called network nodes. Nodes can include hosts such as servers and personal computers, as well as networking hardware. Two devices are said to be networked when a device is able to exchange information with another device." [Computer network. Wikipedia]

"A cable television headend is a master facility for receiving television signals for processing and distribution over a CATV system. The headend facility is normally unstaffed and surrounded by some type of security fencing and is typically a building or large shed housing electronic equipment used to receive and re-transmit video over the local cable infrastructure. One can also find head ends in power line communication (PLC) substations and Internet communications networks." [Cable television headend. Wikipedia]
