When two auto–MDI-X ports are connected together, which is normal for modern products, the algorithm resolution time is typically < 500 ms. However, a ~1.4 second asynchronous timer is used to resolve the extremely rare case (with a probability of less than 1 in 5×10 21 ) of a loop in which each end keeps switching.
In a simple home network, the Internet gateway router connects via Ethernet cable to a powerline adapter, which in turn plugs into a nearby power outlet. A second adapter, plugged into any other outlet in the home, connects via Ethernet cable to any Ethernet device (e.g., computer, printer, IP phone, gaming station). Communications between the ...
Pair production often refers specifically to a photon creating an electron–positron pair near a nucleus. As energy must be conserved, for pair production to occur, the incoming energy of the photon must be above a threshold of at least the total rest mass energy of the two particles created. (As the electron is the lightest, hence, lowest ...
Logitech Unifying receiver (older) Logitech Unifying receiver (newer) Unifying logo The Logitech Unifying Receiver is a small dedicated USB wireless receiver, based on the nRF24L-family of RF devices, [1] that allows up to six compatible Logitech human interface devices (such as mice, trackballs, touchpads, and keyboards; headphones are not compatible) to be linked to the same computer using 2 ...

It is very similar to 1000BASE-LX10 but achieves longer distances up to 40 km over a pair of single-mode fibers due to higher quality optics than a LX10, running on 1310 nm wavelength lasers. It is sometimes referred to as LH (Long Haul), and is easily confused with 1000BASE-LX10 or 1000BASE-ZX because the use of -LX(10), -LH, -EX, and -ZX is ...
A common computer input device, a keyboard. A user presses a key which transfers information to a computer. In computing, an input device is a piece of equipment used to provide data and control signals to an information processing system, such as a computer or information appliance.
Metal-oxide varistor manufactured by Siemens & Halske AG. Modern varistor schematic symbol, which is the same as a thermistor symbol [1]. A varistor (a.k.a. voltage-dependent resistor (VDR)) is a surge protecting electronic component with an electrical resistance that varies with the applied voltage. [2]
