Other Networking Equipment

Computer networking devices are units that mediate data in a computer network. Computer networking devices are also called network equipment, Intermediate Systems (IS) or InterWorking Unit (IWU). more...

Units which are the last receiver or generate data are called hosts or data terminal equipment.

List of computer networking devices

Common basic network devices:

Gateway: device sitting at a network node for interfacing with another network that uses different protocols. Works on OSI layers 4 to 7.; Router: a specialized network device that determines the next network point to which to forward a data packet toward its destination. Unlike a gateway, it cannot interface different protocols. Works on OSI layer 3.; Bridge: a device that connects multiple network segments along the data link layer. Works on OSI layer 2.; Switch: a device that allocates traffic from one network segment to certain lines (intended destination(s)) which connect the segment to another network segment. So unlike a hub a switch splits the network traffic and sends it to different destinations rather than to all systems on the network. Works on OSI layer 2.; Hub: connects multiple Ethernet segments together making them act as a single segment. When using a hub, every attached device shares the same broadcast domain and the same collision domain. Therefore, only one computer connected to the hub is able to transmit at a time. Depending on the network topology, the hub provides a basic level 1 OSI model connection among the network objects (workstations, servers, etc). It provides bandwidth which is shared among all the objects, compared to switches, which provide a dedicated connection between individual nodes. Works on OSI layer 1.; Repeater: device to amplify or regenerate digital signals received while setting them from one part of a network into another. Works on OSI layer 1.;

Some hybrid network devices:

Multilayer Switch: a switch which, in addition to switching on OSI layer 2, provides functionality at higher protocol layers.; Protocol Converter: a hardware device that converts between two different types of transmissions, such as asynchronous and synchronous transmissions.; Brouter: Combine router and bridge functionality and are therefore working on OSI layers 2 and 3.; Digital media receiver: Connects a computer network to a home theatre;

Hardware or software components that typically sit on the connection point of different networks, e.g. between an internal network and an external network:

Proxy: computer network service which allows clients to make indirect network connections to other network services; Firewall: a piece of hardware or software put on the network to prevent some communications forbidden by the network policy;

Other hardware for establishing networks or dial-up connections:
