Common basic networking devices:
*Router: a specialized network device that determines the next network point to which it can forward a data packet towards the destination of the packet. 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 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 sending 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.
*Bridge Router (B router): CombineS router and bridge functionality and are therefore working on OSI layers 2 and 3.
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
Network Address Translator: network service provide as hardware or software that converts internal to external network addresses and vice versa
Other hardware for establishing networks or dial-up connections:
Multiplexer: device that combines several electrical signals into a single signal.
Network Card: a piece of computer hardware to allow the attached computer to communicate by network.
Modem: device that modulates an analog "carrier" signal (such as sound), to encode digital information, and that also demodulates such a carrier signal to decode the transmitted information, as a computer communicating with another computer over the telephone network.
ISDN terminal adapter (TA): a specialized gateway for ISDN.
Line Driver: a device to increase transmission distance by amplifying the signal. Base-band networks only.
