Q:

What are some examples of network topologies?

A:

Quick Answer

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.

There are a number of different examples of topologies.

  • Bus topology
  • 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.

  • Ring topology
  • 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.

  • Star topology
  • 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.

  • Mesh topology
  • 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.

  • Tree topology
  • The tree topology combines the characteristics of star and bus topologies. It includes multiple star configured networks connected to a single backbone cable.

    What is hybrid topology?

    A:

    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.

  • Q:

    What is a good way to visualize a computer network diagram?

    A:

    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.

    What are some types of network security?

    A:

    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.

    What are disadvantages of wired network?

    A:

    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.
