active element means that does not work itself it require external power source for working ie electricity or other
and passive element means that work ifself does not equire external power source for working ie electricity or other
eg. active- compressor need electricity, also tv,computer etc
passive- thermometer sens temperature itself (Mercury thermometer)
Resistor\Capacitor\inductor- passive component
Diode\Transistor\IC- active Component

In active termination scheme it removes the thermal noise which results in the passive termination due to the end resistors..
Active maintenance is for all hard ware components and Passive maintenance for the supporting devices of hard ware components
In a active heatsink system you have both a heatsink and a fan thus for the most part an active heatsink cools better with one exception. Should the fan fail the active heatsink will quickly overheat. Passive heatsinks relay on transferring heat without the aid of a fan. The advantage here is that a passive heatsink is fail proof and uses 0 electricity, however passive heatsinks don't typical cool as well. Passive heatsinks work great for supporting chips and RAM cooling. They are also found in servers because of the no fail aspect. EnzoTech produces some passive heatsinks you can read a bit more about them here: http://electricalninja.com/
ACTIVE COMPONENTS The components which produce the energy in the form of current or voltage are called as active components. Example:transistors etc,. PASSIVE COMPONENTS The components which stores the energy in the form of current or voltage are called as passive components. example:inductors,resistors,capacitors etc,.

An active device is a device that takes input energy to operate. The only energy a diode uses is from the signal applied to it (it has one input, one output, and no other terminals), so it is a passive device. To be an active device, a separate power source must be applied to it - such as the case for operation amplifiers, for example.
Passive
Passive element. An active element is an element that can generate power. Capacitors can't generate power, hence they are passive elements.
The passive voice must have the verb 'to be' in the correct tense plus the past participle of the main verb. Here are some examples: I do (active)/it is done (passive) I did (active)/it was done (passive) I am doing (active)/it is being done (passive) I was doing (active)/it was being done (passive) and so on
The passive voice must have the verb 'to be' in the correct tense plus the past participle of the main verb. Here are some examples: I do (active)/it is done (passive) I did (active)/it was done (passive) I am doing (active)/it is being done (passive) I was doing (active)/it was being done (passive) and so on So to change protect into the passive would be I protect (active)/ It is protected (passive)
No. The passive voice must have the verb 'to be' in the correct tense plus the past participle of the main verb. Here are some examples: I do (active)/it is done (passive) I did (active)/it was done (passive) I am doing (active)/it is being done (passive) I was doing (active)/it was being done (passive) and so on
passive attacks : footprinting, trashing active attacks : sniffing, social engineering
Active: She hits the table. 'She' is the subject and is doing the action. Passive: The table is hit by her. 'She' (or 'her' in this case) is doing the action but is not the subject.
A; Any components that provide gain/loss are active device resistors, capacitors are passive
Capacitors and inductors are considered passive elements, not active elements, because capacitors and inductors do not supply or amplify energy. An example of an active element is a battery, which supplies energy to a circuit.
A verb is said to be in the passive voice when the subject of the sentence is acted upon by the verb, rather than performing the action. In passive voice constructions, the focus is on the recipient of the action rather than the doer. A common indicator of passive voice is the inclusion of a form of "be" (e.g., is, was, were) with the past participle of the main verb.
all passive elements which absorb energy from active elements can control the flow of electrons
No, the transistor is very active; slight changes to the input at the base produce dynamic and substantial activity at the collector. Both resistors and coils are examples of passive elements/devices because their individual tasks and values are firmly set and do not vary.
