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,.

The active components required biasing voltage for proper operation and they are mostly used for amplification e,g. transistor where as passive components did not required any biasing voltage e.g, resistor,capacitor,inductor
Active maintenance is for all hard ware components and Passive maintenance for the supporting devices of hard ware components
Heatsink uses what they call passive cooling where as liquid cooling systems use active cooling.
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)
In active termination scheme it removes the thermal noise which results in the passive termination due to the end resistors..
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/

Passive Load is Load comprising of Passive Components Active Load is the Load comprising of Active Components In Test Boards its better to use Active Loads, If you are concerned about Temperature Variations during characterisation
active components can have gain, passive can't.
Active components can deliver a finite amount of power for some finite amount of time period where passive components can not deliver finite amount of power for some finite amount of time.
What is the difference between active attacks passive attacks in GSM network?
Active transport requires energy; passive transport does not.
Active means devices that perform functions in a non linear fashion [amplifiers] passive are components that perform according to a set of linear rules
The difference between a passive and an active dividend policy lies in the amount of time between dividend disbursement. In a passive dividend policy, dividends are given when the company decides it is time. With an active dividend policy, dividends are disbursed at regular intervals.
The difference between active and passive transport, is that, active transport, requires energy input from the cell, in order to occur, unlike passive, which occurs, without any energy input.

Fiber optic couplers can be either active or passive devices. The difference between active and passive couplers is that a passive coupler redistributes the optical signal without optical-to-electrical conversion. Active couplers are electronic devices that split or combine the signal electrically and use fiber optic detectors and sources for input and output.
Electronic have two type of components Active components and Passive components. Active components are those which increase the power of a signal and must be supplied with the signal and a source of power. Passive components do not increase the power of a signal. Active components are Bipolar transistor, Operational amplifier, field effect transistors etc and Passive components are semiconductor, resistor, capacitor, inductor etc
