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 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 ...
In this diagram the router is a single point of failure for the communication network between computers. A single point of failure ( SPOF ) is a part of a system that would stop the entire system from working if it were to fail . [ 1 ]

Fail-safe and fail-secure are distinct concepts. Fail-safe means that a device will not endanger lives or property when it fails. Fail-secure, also called fail-closed, means that access or data will not fall into the wrong hands in a security failure. Sometimes the approaches suggest opposite solutions.
By far the most popular FCS algorithm is a cyclic redundancy check (CRC), used in Ethernet and other IEEE 802 protocols with 32 bits, in X.25 with 16 or 32 bits, in HDLC with 16 or 32 bits, in Frame Relay with 16 bits, [3] in Point-to-Point Protocol (PPP) with 16 or 32 bits, and in other data link layer protocols.
The ASi-5 system is open for the use of parameter interfaces such as e.g. IO-Link. IO-Link devices can be efficiently collected over long distances and could be integrated cyclically up to 32 bytes. 16 safe bits are available for safety-related switching devices, such as emergency stop, light curtains, safety switches and similar are available.
Network timeout preventing a Web browser from loading a page. In telecommunications and related engineering (including computer networking and programming), the term timeout or time-out has several meanings, including: A network parameter related to an enforced event designed to occur at the conclusion of a predetermined elapsed time.
