The chief characteristic of such hub-and-spoke industrial districts is the importance of one or more large companies, usually in one industrial sector, surrounded by smaller, associated businesses. Examples of cities with such districts include Seattle (where Boeing was founded), Silicon Valley (a high tech hub), and Toyota City, with Toyota.
For example, the sample diagram does not indicate the physical type of connection between the PCs and the switch, but since a modern LAN is depicted, Ethernet may be assumed. If the same style of line was used in a WAN (wide area network) diagram, however, it may indicate a different type of connection.
These hubs serve as the common connections mediating the short path lengths between other edges. By analogy, the small-world network of airline flights has a small mean-path length (i.e. between any two cities you are likely to have to take three or fewer flights) because many flights are routed through hub cities. This property is often ...
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.
Network topology is the arrangement of the elements (links, nodes, etc.) of a communication network. [1] [2] Network topology can be used to define or describe the arrangement of various types of telecommunication networks, including command and control radio networks, [3] industrial fieldbusses and computer networks.
A network switch (also called switching hub, bridging hub, Ethernet switch, and, by the IEEE, MAC bridge [1]) is networking hardware that connects devices on a computer network by using packet switching to receive and forward data to the destination device.
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. Hubs are highlighted. A hub is a component of a network with a high-degree node ...
Network problems that involve finding an optimal way of doing something are studied as combinatorial optimization.Examples include network flow, shortest path problem, transport problem, transshipment problem, location problem, matching problem, assignment problem, packing problem, routing problem, critical path analysis, and program evaluation and review technique.
