Networksystems of interconnected components are called networks. Specific examples include:
- transport networks,
- electric circuits - a network of electrical components.
- electricity networks (electric power - generation, transmission and distribution).
- social networks and business networks, studied in sociology and economics
- computer networks, which transfer information between computers. (Specific configurations include star networks and grid networks.) The Internet is a large-scale computer network. Also, a website and the whole World Wide Web are networks of webpages, a link web. Note: A distinction is made between wide area networks, (WANs) and local area networks (LANs)
- telecommunications networks
- public switched telephone networks, which route audio signals from one telephone to another
- radio networks, which create and distribute radio programming
- television networks, which create and distribute television programming
- financial networks, for applications such as funds transfer and credit card authorization.
- network externality in economics
- neural network
Networks can be characterized in a number of different ways. For example, many networks are observed to be scale-free networks, in which a few network nodes act as "very connected" hubs.
