A dongle (center, in white) allowing an ethernet cable (left, in grey) to be connected to a Thunderbolt port on a laptop (right). A dongle is a small piece of computer hardware that connects to a port on another device to provide it with additional functionality, or enable a pass-through to such a device that adds functionality.

The bridge has three ports. A is connected to bridge port 1, B is connected to bridge port 2, C is connected to bridge port 3. A sends a frame addressed to B to the bridge. The bridge examines the source address of the frame and creates an address and port number entry for host A in its forwarding table. The bridge examines the destination ...
A bridge router or brouter [1] is a network device that works as a bridge and as a router. The brouter routes packets for known protocols and simply forwards all other packets as a bridge would. [2] Brouters operate at both the network layer for routable protocols and at the data link layer for non-routable protocols. As networks continue to ...
The network controller implements the electronic circuitry required to communicate using a specific physical layer and data link layer standard such as Ethernet or Wi-Fi. [a] This provides a base for a full network protocol stack, allowing communication among computers on the same local area network (LAN) and large-scale network communications through routable protocols, such as Internet ...
Ethernet over USB is the use of a USB link as a part of an Ethernet network, resulting in an Ethernet connection over USB (instead of e.g. PCI or PCIe).. USB over Ethernet (also called USB over Network or USB over IP) is a system to share USB-based devices over Ethernet, Wi-Fi, or the Internet, allowing access to devices over a network.
A device capable of more than bridging is known as a multilayer switch. A layer 2 network device is a multiport device that uses hardware addresses (MAC addresses) to process and forward data at the data link layer (layer 2). A switch operating as a network bridge may interconnect otherwise separate layer 2 networks.
It is also called data communication(s) equipment [2] [3] [4] and data carrier equipment. [ citation needed ] Usually, the DTE device is the terminal (or computer ), and the DCE is a modem . In a data station , the DCE performs functions such as signal conversion, coding , and line clocking and may be a part of the DTE or intermediate equipment ...
A null modem cable is a specially wired cable connected between the serial ports of two devices, with the transmit and receive lines reversed. It is used to connect two devices directly without a modem. The same software or hardware typically used with modems (such as Procomm or Minicom) could be used with this type of connection.
