What is a coaxial cable? Coaxial cable consists of a copper wire surrounded by a concentric conducting shield, separated by an insulating material. Also known as coax cable, this type of cable is ideal for carrying high-frequency electrical signals with low losses. Coaxial cables are an efficien...
Go straight to the solution. A wifi-direct connection is one that connects two devices directly. It’s as if a wire were connecting the remote and the Roku. It does not use your router’s wifi network, so you cannot connect to the internet through it. Expert in Roku Community Streaming....
Working voltage and power rating— A coaxial cable’svoltagetravels through the center wire or conductor. Each cable has a calculated maximum or “peak” voltage, which is then slightly reduced as a safety precaution. Signal loss at specific frequencies— Coaxial cable lines can be susceptible to...
Coaxial cable received its name because it includes one physical channel that carries the signal surrounded by another concentric physical channel, both running along the same axis. The innermost channel is typically a copper wire, which is then surrounded by a layer of insulation between it and t...
That power is consumed by power supplies (the black cubes—sometimes called "vampires"—converting AC into DC), the circuits and sensors needed to receive a remote signal, soft keypads and displays including miscellaneous LED status lights. Standby power use is also caused by circuits that ...

1. Alternatively called a cord, connector, or plug, a cable is one or more wires covered in plastic that transmits power or data between devices or locations. The picture shows what the U.S. power cord may look like for your computer or monitor. The power cord is one example of ...
communication channel is divided into multiple logical channels. Then, the individual electrical or electromagnetic network signals are input into a multiplexer (mux) that combines them into a composite signal. The conductor used to transmit the signal is often acopper wireor a fiber optic cable. ...
In an optical audio setup, the digital electrical signal from the source -- say, a DVD player -- is converted into light by a device called a transmission module. In Toslink, this module consists of an LED, or light-emitting diode, and a drive circuit, usually sent through plastic fiber...
