active speaker has its own built-in power amplifier and mic/line input jacks and controls. A passive speaker needs an external amplifier to produce audio. See similar questions...

Ans. An active component is a VisualWorks component whose widget is a View and has a Model and a Controller. A passive component is a VisualWorks component whose widget is not a View and it does not depend on a model and a controller. See similar questions...

Active RFID tags have a battery, which is used to run the microchip's circuitry and to broadcast a signal to a reader (the way a cell phone transmits signals to a base station). Passive tags have no battery. Instead, they draw power from the reader, which sends out electromagnetic waves that induce a current in the tag's antenna. Semi-passive tags use a battery to run the chip's circuitry, but communicate by drawing power from the reader. See similar questions...

Active, or real-time GPS, means you can request and receive location data from your GPS receiver while your vehicle is on the road. Passive, or non real-time GPS, means your GPS receiver stores all location information for you to access at a later time. Normally, a passive receiver transmits this data at the end of the day, when your vehicle returns to your yard. With a passive system, you get all of the same information as the active system, but in a different time frame. See similar questions...

You can either apply as an active or passive participant. Active means, you want to present your work at the congress. Passive means, you will be able to listen to other's presentations and enjoy social program, without presenting anything. See similar questions...

Passive direct boxes use a transformer to convert the electrical signals while active direct boxes use an amplifier circuit. Passive boxes have the advantage of providing isolation which can reduce ground hum in systems. See similar questions...

Active RFID uses an internal power source (a battery) within the tag to continuously power the tag and its RF communication circuitry that generate the outgoing signal. Active RFID allows extremely low-level RF signals to be received by the tag (since the reader/interrogator does not power the tag), and the tag can generate high-level signals back to the reader/interrogator. See similar questions...

Active sensors pulse energy at a target and measure the return, or reflection. Light Detection and Ranging (LIDAR) and Radio Detection and Ranging (RADAR) are two examples of active sensors. Passive sensors collect the sun's ambient light energy reflected from a surface with no active pulse of energy from the sensor. Film-based and digital cameras, both aerial and handheld, as well as digital satellite sensors, such as Landsat Thematic Mapper, are examples of passive sensors. See similar questions...

Active direct boxes require power such as a separate power supply, 48V phantom power, or a battery to activate their circuits while passive direct boxes convert the signal from high-Z to low-Z using only a transformer. Passive DI's do not require a power supply to work. See similar questions...

Active GPS antennas include a built-in Low Noise Amplifier which provides sufficient gain to overcome coax cable losses while providing the proper signal level to the GPS receiver. Active GPS antennas require power from the Passive GPS antennas do not include a Low Noise Amplifier and are best suited to GPS applications requiring a short distance, 1 inch to 3 feet, between the GPS receiver and antenna. Passive antennas require an LNA on the GPS receiver. See similar questions...

Active transponders have their own power supply (battery). Passive cards/chips, which do not have a battery, must be supplied with energy by the reader or lock. Typically active tags have a longer range than passive tags. See similar questions...

Active crossovers are more efficient than passive crossovers. A typical "insertion loss" (power loss due to use) of a passive crossover is around 0.5dB. Active crossovers have much lower insertion losses, if they have any loss at all, since the losses can effectively be negated by adjusting the amplifier gain. Also, with some active crossovers, you can continuously vary not only the crossover point, but also the slope. See similar questions...

Active-Active is referring to full redundancy all the way through and each HDD is actively connected to both initiators at all times, and replacement can be made any time with zero down time. Passive-Active means the replacement on the failed component can only be made system shutting down, and the fail-over path is not active while the other path is still working. Depending how JBOD1 is offline. See similar questions...

Active ROM exercise is performed independently by the client. Passive ROM exercise is performed by a nurse or other health care worker to maintain or restore a client’s mobility. See similar questions...

The manual machine mode is featured in both the Basic Model LVM-1518 and the Motorized Model KSA-7781. To use manual mode when using the Motorized Model, simply don't activate the motor, and the movement will be the same as the Basic Model. (It is like having two machines for the price of one!) The resistance adjustment is designed for use only when in the manual machine mode to minimize wear and tear on the motor. See similar questions...

Both the FTP client and server processes should be capable of active and passive connections. When a process is in passive mode, it will "listen" (accept incoming connections) on a data port. The active process will then "connect" (outgoing) to that port and the transfer will start. The FTP request command determines the direction of the connection. See similar questions...
