The electrical network which has its own energy sources like current or voltage sources within the circuit is called as an active electrical network
Let see an example. The active power absorbed by an AC motor is used to produce mechanical power delivered on the output shaft. If the mechanical power is negative (the motor is pushed to work as a brake) the active power 'absorbed' is also negative. The motor converts the mechanical power in active electrical power delivered in the electrical network. Any AC generator is supplied with negative active power, or it deliver to the network positive active power.
An electrical network is a system for supplying electricity in a given region.
What is the difference between active attacks passive attacks in GSM network?
The total active power in a network is the sum of the individual active powers because active power represents the rate at which energy is consumed or converted into useful work. In both series and parallel configurations, all components draw from the same source, ensuring that the total energy supplied is equal to the sum of the energy consumed by each component. This principle holds true regardless of the arrangement because power is additive in electrical systems. Thus, the overall active power is simply the collective contribution of all components in the network.
Active Directory service is used to store information about the network resources across a domain and also centralize the network.
The grid. The countrywide network is the National Grid
I know of one: http://www.sailorbits.com . Its active
Passive elements don't require power from the supply to produce its effect on a signal. They derive the power of the input signal to perform its action. for example, a resistor doesn't require a separate supply to provide its action of resistance in a circuit. Where as in active elements there should be a power source for its working. They require a supply for there working. For instance, transistors - Only after biasing the transitor in required region of operation, its characteristics are applied on the signal. ie, for amplification, transistor require a source from where it can work in.
The Active topology functionally allow you to make element inactive (and chnage them back active again).

If I divide the term into words as (Passive + Linear + Bilateral ) Network then it would be easier to understand. 1st of all, Passive Network is a network that includes **passive electrical / electronic components. Then, Linear Network is consists of passive electrical / electronic components whose parameters such as resistance, capacitance or inductance are constant with respect to current or voltage and in such network each voltage or current source act independently of each other. After that, Bilateral Network is the network in which the magnitude of current remains the same when the voltage polarity is reversed. So, A Passive linear bilateral network includes passive components that exhibit linearity and at the same time magnitude of current is independent of the polarity of voltage. ** Passive electronic components are Resistor, Inductor or Capacitor, they by themselves are not capable of amplifying or processing an electrical signal.
It represents the electrical characteristics of individual network components, but does not provide any information pertaining to the network connections.
