Motherboard of the NeXTcube from 1990 having a Motorola 68040 (25 MHz) and a digital signal processor Motorola 56001 with 25 MHz which was directly accessible via an interface. In most designs the 56000 is dedicated to one single task, because digital signal processing using special hardware is mostly real-time and does not allow any interruption .
The PIA is designed for glueless connection to the Motorola 6800 style bus, and provides 20 I/O lines, which are organised into two 8-bit bidirectional ports (or 16 general-purpose I/O lines) and 4 control lines (for handshaking and interrupt generation). The directions for all 16 general lines (PA0-7, PB0-7) can be programmed independently.
A network interface controller (NIC, also known as a network interface card, [3] network adapter, LAN adapter and physical network interface [4]) is a computer hardware component that connects a computer to a computer network. [5] Early network interface controllers were commonly implemented on expansion cards that plugged into a computer bus.
Canopy – A line-of-sight wireless technology, primarily used by ISPs to provide broadband internet; MotoMESH – A mobile wireless broadband product providing proprietary "Mesh-Enabled Architecture" and standards-based 802.11 network access in both the unlicensed 2.4 GHz band and the licensed 4.9 GHz public-safety band
In telecommunications, a network interface device (NID; also known by several other names) is a device that serves as the demarcation point between the carrier's local loop and the customer's premises wiring. Outdoor telephone NIDs also provide the subscriber with access to the station wiring and serve as a convenient test point for ...
Networking cable is a piece of networking hardware used to connect one network device to other network devices or to connect two or more computers to share devices such as printers or scanners. Different types of network cables, such as coaxial cable , optical fiber cable , and twisted pair cables, are used depending on the network's topology ...
In network topology, a cable modem is a network bridge that conforms to IEEE 802.1D for Ethernet networking (with some modifications). The cable modem bridges Ethernet frames between a customer LAN and the coax network. Technically, it is a modem because it must modulate data to transmit it over the cable network, and it must demodulate data ...
A crossover cable may also be used to connect two hubs or two switches on their upstream ports. Because the only difference between the T568A and T568B pin and pair assignments are that pairs 2 and 3 are swapped, a crossover cable may be envisioned as a cable with one modular connector following T568A and the other T568B (see TIA/EIA-568 wiring ...
