Hubs are now largely obsolete, having been replaced by network switches except in very old installations or specialized applications. Repeater hubs also participate in collision detection, forwarding a jam signal to all ports if it detects a collision.

A hub works at the physical layer (layer 1) of the OSI model. It has multiple input/output (I/O) ports, in which a signal introduced at the input of any port appears at the output of every port except the original incoming. Repeater hub: for connecting multiple Ethernet devices together and making them act as a single network segment.Repeater: an electronic device that receives a signal and retransmits it at a higher level or higher power, or onto the other side of an obstruction, so that the signal can cover longer distances.Bridge: a device that connects multiple network segments.Unlike less advanced network hubs, a network switch forwards data only to one or multiple devices that need to receive it, rather than broadcasting the same data out of each of its ports. Switch: a device that connects devices together on a computer network, by using packet switching to receive, process and forward data to the destination device.A data packet is typically forwarded from one router to another through the networks that constitute the internetwork until it reaches its destination node. Routers perform the "traffic directing" functions on the Internet. Router: a networking device that forwards data packets between computer networks.Gateway: an interface providing a compatibility between networks by converting transmission speeds, protocols, codes, or security measures.Network hardware can be classified by its location and role in the network.Ĭore network components interconnect other network components. As technology advances and IP-based networks are integrated into building infrastructure and household utilities, network hardware will become an ambiguous term owing to the vastly increasing number of network capable endpoints. Taking a wider view, mobile phones, tablet computers and devices associated with the internet of things may also be considered networking hardware. Other networking hardware used in computers includes data center equipment (such as file servers, database servers and storage areas), network services (such as DNS, DHCP, email, etc.) as well as devices which assure content delivery.

Wireless networking has become increasingly popular, especially for portable and handheld devices. The most common kind of networking hardware today is a copper-based Ethernet adapter which is a standard inclusion on most modern computer systems. Networking devices includes a broad range of equipment which can be classified as core network components which interconnect other network components, hybrid components which can be found in the core or border of a network and hardware or software components which typically sit on the connection point of different networks.
