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.

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.

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.

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.

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.

This is somewhat similar to comparing dynamic mics to condensers. Active DI’s have a built-in pre-amp that requires power to run while passive DI’s use a transformer to convert the signal. Both ‘transform’ or convert the instrument’s high-impedance output to a low impedance balanced microphone level. This allows long cable runs without adding unwanted noise and will improve the instrument’s sound quality. The J48 uses phantom power to derive its power source.

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.

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.

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.

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.

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.

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 GPS receiver to operate, through the GPS receiver antenna connector. 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.

In the early days of bass playing, players had instruments that had both passive tone controls (or EQ) and pickups. This meant that the sound from the pickup could only be altered by "cutting" certain frequencies or parts of the tone. Later, manufacturers connected a pre-amp to the passive pickups, which allowed players to not only cut frequencies, but boost certain ones as well. This type of electronics requires a battery or some other power source to function.

active ISDN card handles most of the ISDN connection protocols (dialing, accepting calls, etc.) itself. The card includes a kind of minicomputer with its own software (firmware). With a passive card, the computer in which the card is installed has to perform these functions. In principle, both types are supported by isdn4linux. However, since active cards have non-standard interfaces, a driver can only be made when the producer publishes the specifications for the interface.

Active tags have a battery on the tag. The battery may be used to boost read/write range, allow for larger memories, or add sensory and data logging capabilities, such as temperature sensing. Passive tags receive all of their energy from the read/write device that "powers" the tag to allow it to transmit data.

Probably. Even though they put passive electronics in many instruments, for the most part they used low impedance (active) pickups. These can be wired with either active or passive tone controls. We recommend checking with the pickup manufacturer first before doing any work though. They can tell you exactly which pickups you have and what wiring options are available.

A26 - Active loudspeakers make very efficient use of amplifier power, allow drivers of vastly different voltage sensitivity to be used together, and give maximum control over the motion of each voice coil. A 2-way speaker with passive crossover, for example, may run into amplifier clipping on a big bass note. In this process the high frequency tweeter signal, which is riding on top of the bass waveform, gets chopped off in the amplifier, causing large amounts of very high frequency distortion.
