Network devices, also called network hardware or computer network devices, are computer network equipment or electronic devices needed for interaction and communication between various devices on a local computer network. They mediate communications in a local computer network by using one or more transceivers. These devices are used to exchange data between the devices in the network, either for processing or transmitting the data. The data transmitted through these devices are called packets. Standard Ethernet, VoIP, Fast Path, and ATM networks utilize Ethernet technology, while wireless networks utilize radio frequency technology. One type of network device is the hub. A hub is a hub router, which is a computer that contains one or more hubs. The number of hubs will depend on the total number of computers in the area that the hub locates.
All networking hardware is typically found in the form of plugs, routers, physical devices, and controllers.
