Generically, an NID may also be called a network interface unit (NIU), [1] telephone network interface (TNI), system network interface (SNI), or telephone network box. Australia's National Broadband Network uses the term network termination device or NTD. A smartjack is a type of NID with capabilities beyond simple electrical connection, such ...
The primary purpose of a DS1 Network Interface Unit, T1-NIU (AKA Smartjack to many) is to provide a remote test point to the service provider to a DS1 (T1) circuit at the Network Interface (NI). In simple terms, a T1-NIU provides full DS1 loopback towards the network to permit a service provider to test to the NI from a central test center 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 ...
It displays network latency and network loss at intermediate hops between a source and destination. Because it displays the degree of packet loss at any given router or link, it can also be used to determine which routers or subnets might be having network problems. [7]
A wireless network interface controller may be implemented as an expansion card and connected using PCI bus or PCIe bus, or connected via USB, PC Card, ExpressCard, Mini PCIe or M.2. The low cost and ubiquity of the Wi-Fi standard means that many newer mobile computers have a wireless network interface built into the motherboard.
Network interface may refer to: Network interface controller, a computer hardware component that connects a computer to a computer network; Network interface device, a device that serves as the demarcation point between a telephone carrier's local loop and the customer's wiring; Virtual network interface, an abstract virtualized representation ...
Microsoft Windows and other operating systems regard voice-band modems as part of the hardware of the computer, and similarly to other parts of the computer's hardware such as the mouse or hard disk are configured through the Windows Control Panel. In contrast, DSL routers are regarded as separate nodes in the LAN (local area network).
Therefore, the NDIS acts as the interface between the media access control (MAC) sublayer, which is the lower sublayer of the data link layer, and the network layer (layer 3). The NDIS is a library of functions often referred to as a " wrapper " that hides the underlying complexity of the NIC hardware and serves as a standard interface for ...
