Active satellite can generate power for its own operation. It is known as active repeater due to its functionality. Passive Satellite : The passive satellite is a reflector which receives the signal from the transmitting earth station and scatters the signal in all the directions.

What are passive and active scanning? ... During an active scan, the client radio transmits a probe request and listens for a probe response from an AP. With a passive scan, the client radio listens on each channel for beacons sent periodically by an AP.

Active solar energy systems use the same principles as passive systems except that they use a fluid (such as water) to absorb the heat. ... Photovoltaic cells, or solar panels, are slightly more involved than passive or active solar energy systems. They convert sunlight to electricity by using thin sheets of silicon.

The primary difference is that cable comes through a wired connection while satellite is wireless (until it reaches your house, anyway).

A prominent difference between active and passive immunity is that active immunity is developed due to the production of antibodies in one's own body, while passive immunity is developed by antibodies that are produced outside.

Active transport requires chemical energy because it is the movement of biochemicals from areas of lower concentration to areas of higher concentration. On the other hand, passive transport moves biochemicals from areas of high concentration to areas of low concentration; so it does not require energy.

In a satellite link delay from earth to satellite to earth is about 240ms while in terrestrial link it will be far less. But transmission cost in a satellite system is independent of the distance within the area of coverage of the satellite antenna, while in terrestrial system it varies based on the distance.

What exactly is the difference between passive and active flexibility? Passive flexibility is when your muscles are placed into a position by some outside force, usually another body part. ... Active flexibility is when you are only using the muscles in the body part you are stretching.

Active and passive learning are different methodologies for acquiring knowledge in the learning process. Active learning involves the student in the learning process and its methodologies are student-centered while passive learning does not involve the student and is mainly teacher-focused.

Active night vision systems involve a camera and a bright light that emits near infrared radiation (which happens to be invisible to the naked eye). The camera is sensitive to this light and picks it up. ... Passive night vision systems use an image intensifier tube to amplify existing light.

Cable and satellite both function by letting you “tune in” to specific channels within that signal. The primary difference is that cable comes through a wired connection while satellite is wireless (until it reaches your house, anyway).

Here's the difference. Passive forces are forces without an obvious agent to produce them and they changes in response to other forces. ... Your argument on the previous answer is sound; that Active Forces have fixed values independent of other forces acting, while passive forces do not."

The main difference between the two is that active transport requires chemical energy in the form of ATP while passive transport requires no outside energy. The biggest similarity between the two is that they both involve the movement of chemicals through a membrane.

Active vs. Passive Voice. Active voice means that a sentence has a subject that acts upon its verb. Passive voice means that a subject is a recipient of a verb's action.

What are passive and active scanning? ... A client can use two scanning methods: active and passive. During an active scan, the client radio transmits a probe request and listens for a probe response from an AP. With a passive scan, the client radio listens on each channel for beacons sent periodically by an AP.

The most significant difference between the active and reactive power is that the active power is the actual power which is dissipated in the circuit. Whereas, the reactive power is the useless power which only flows between the source and load.

The biggest difference when it comes to motion between the two technologies used for 3D TVs is that Active 3D shows left/right frames in sequence, while Passive 3D shows them simultaneously. This creates an issue when there is movement on the screen.
