A physical Wake-on-LAN connector (white object in foreground) featured on the IBM PCI Token-Ring Adapter 2. Wake-on-LAN (WoL or WOL) [a] is an Ethernet or Token Ring computer networking standard that allows a computer to be turned on or awakened from sleep mode by a network message.
Standby power, also called vampire power [1], vampire draw, phantom load, ghost load, or leaking electricity, refers to how electronic and electrical appliances consume electric power. At the same time, they are switched off (but are designed to draw some power) or in standby mode. It only occurs because some devices claim to be "switched off ...
In this configuration, an Ethernet connection includes Power over Ethernet (PoE) (gray cable looping below), and a PoE splitter provides a separate data cable (gray, looping above) and power cable (black, also looping above) for a wireless access point. The splitter is the silver and black box in the middle between the wiring junction box (left ...
This is done because labor costs are higher than the cost of the cable, and running extra cable reduces future labor costs if networking needs change. Link aggregation can allow the use of these extra cables to increase backbone speeds for little or no extra cost if ports are available.
Some devices, such as 2.5-inch drives, can operate off the 5 V supplied by laptop eSATAp ports. Others, such as 3.5-inch drives, also require 12 V; they can be powered from a desktop eSATAp port, but require an external 12 V power supply if used with a laptop computer. This can lead to confusion if users are not aware of the distinction.
In telecommunications, insertion loss is the loss of signal power resulting from the insertion of a device in a transmission line or optical fiber and is usually expressed in decibels (dB). If the power transmitted to the load before insertion is P T and the power received by the load after insertion is P R , then the insertion loss in decibels ...
Map Network Drive dialog in Windows 10, connecting to a local SMB network drive. Server Message Block (SMB) is a communication protocol [1] used to share files, printers, serial ports, and miscellaneous communications between nodes on a network.
Today, few consumer-grade PC-compatible computers include COM ports, [3] though some of them do still include a COM header on the motherboard. [4] After the RS-232 COM port was removed from most consumer-grade computers, an external USB-to-UART serial adapter cable was used to compensate for the loss. A major supplier of these chips is FTDI.
