The uprise of hubs in scale-free networks is associated with power-law distribution. Hubs have a significant impact on the network topology. Hubs can be found in many real networks, such as the brain [2] or the Internet. Network representation of brain connectivity. Hubs are highlighted Partial map of the Internet based on the January 15, 2005 ...
The hub is the server and the peripherals are the clients. The network does not necessarily have to resemble a star to be classified as a star network, but all of the peripheral nodes on the network must be connected to one central hub. All traffic that traverses the network passes through the central hub, which acts as a signal repeater.
Here, the pitcher represents the original source and the water is the content being spread. The funnels and connecting tubing represent the nodes and the connections between nodes, respectively. As the water passes from one funnel into another, the water disappears instantly from the funnel that was previously exposed to the water.
The hub manages and controls all functions of the network. It also acts as a repeater for the data flow. In a typical network the hub can be a network switch, ethernet hub, wireless access point or a router. The star topology reduces the impact of a transmission line failure by independently connecting each host to the hub.
The San Francisco System (also known as the "Hub and Spokes" architecture) is a network of alliances pursued by the United States in the Asia-Pacific region, after the end of World War II [1] – the United States as a "hub", and Japan, South Korea, Taiwan, the Philippines, Thailand, Australia, and New Zealand as "spokes".

Point-to-point (top) vs hub-and-spoke (bottom) networks. The hub-and-spoke model, as compared to the point-to-point model, requires fewer routes. For a network of n nodes, only n − 1 routes are necessary to connect all nodes so the upper bound is n − 1, and the complexity is O(n).
Hyperlink-Induced Topic Search (HITS; also known as hubs and authorities) is a link analysis algorithm that rates Web pages, developed by Jon Kleinberg.The idea behind Hubs and Authorities stemmed from a particular insight into the creation of web pages when the Internet was originally forming; that is, certain web pages, known as hubs, served as large directories that were not actually ...
