List any four topologies used for networking purpose?
Bus, Mesh, Star, Ring.
Regional Network http://en.wikipedia.org/wiki/Computer_network ---- There are four basic types of network topologies: bus, ring, star, and mesh. There are also many other types as well, but they are hybrid topologies, meaning they are a combination of two or more of the four basic topologies. Two examples of hybrid topologies are the star bus topology and the star ring topology.
The bus topology is one of the four main topology types for networking. It allows systems to be connected in a straight line without any other network connectivity devices. As a result, it is easy to construct and needs very little in the way of configuration, and is inexpensive compared to other topologies. The main result of any topology is to connect clients together in order to share resources.
Network Topology refers to the way that cables and other pieces of hardware connect to one another. There are four common "base" types of topologies: bus, ring, star, and mesh. There are other types as well, but these are referred to as "hybrid topologies." The most commonly used network topology is a hybrid topology called the Star Bus Topology.
