The basic examples of network topologies used in local area networks include bus, ring, star, tree and mesh topologies. A network topology simply refers to the schematic description of how connecting lines and nodes are arranged in a network. A topology can either be described as physical or logical.Continue Reading
There are a number of different examples of topologies.
In the bus topology, a common backbone is used to connect every node in the network. The backbone is a single cable that acts as the shared connection for all the nodes attached into it via interface connectors.
All the nodes in a ring topology are connected to each other in the form of a closed loop. Every node on the network is only connected to two other nodes. It is the cheapest network topology to establish and provides high data transfer rates.
The star topology has a single, central hub, to which every node on the network is connected to. Data being transmitted between the network nodes has to pass through the central hub.
The devices in a mesh topology have redundant data paths. Each device on the network has a point-to-point connection with every other device on the network. This topology offers a fault tolerance in that if a switch, hub, wire or any other component fails, the data always has an alternative path to follow.
The tree topology combines the characteristics of star and bus topologies. It includes multiple star configured networks connected to a single backbone cable.
Hybrid topology is the interconnection of two or more basic topologies, each of which is laid out so the resulting network does not display a standard topology. Two examples of a hybrid-type network are the star bus network and star ring network. The term "topology" references the layout pattern of the connected devices, or the interconnections of computers, networks and links.Full Answer >
Computer networks are classified by five main types and may be visualized as the objects for which the types are named: bus, ring, star, tree and mesh. The pattern of device connections relative to the network's server or router is called network topology, and visualizing topology as a familiar object helps users understand and remember a network's function. Networks may be single types or combinations.Full Answer >
Network security systems consist of hardware and software components that help protect a network from unauthorized access, misuse or denial of service to networks and their data. Network security components often include anti-virus, anti-malware and anti-spyware software; hardware and software firewalls; intrusion protection systems, or IPS; and virtual private networks, or VPNs. These and other components working in tandem protect the usability, reliability, integrity and safety of a network and its data against an ever-changing array of threats.Full Answer >
A wired network is a network connection that connects devices to other networks or the Internet using cables. One of the main disadvantages of a wired network is running cables in difficult areas through ceilings, walls and floors. The cables also need to be run from one computer to another, a process which can be time consuming.Full Answer >
