what does efficient mean>?

Answer 1

Maximum result with minimum effort or expenditure.

Answer 2

What Does Efficient Mean

Answer 3

Efficient is a relative term and usually subjective and situational.
There are many examples of extremely efficient systems that do not gain large acceptance because the person trying to do an objective analysis will judge the results of a test in terms of their own personal experiences.
For example binary numbers are more efficient than decimal numbers because they have many advantages. (We can teach rocks how to do arithmetic in binary easier than we can teach them how to do it in decimal. (Computers are made of transistors made of silicon; most rocks are made of silicon.))
You (and I) will probably go on using decimal numbers (mostly) for various reasons.
"Progress" is made when a consensus for a standard is reached.
In science efficient means /
I have "cheated" here because "progress" and are relative, subjective, situational terms that most people use axiomatically.

Answer 4

Efficiency as a technical term may refer to:

Energy efficiency, useful work per quantity of energy
Energy conversion efficiency, desired energy output per energy input
Energy conservation, reducing the use of energy
Electrical efficiency, useful power output per electrical power consumed
Fuel efficiency, converting energy in fuel to kinetic energy or work
Specific impulse, in propulsion systems, a measure of fuel-efficiency
Volumetric efficiency, in internal combustion engine design
Lighting efficiency, visible light from a light source per unit of energy, in lumens per watt
Mechanical efficiency, the effectiveness of a simple machine, mechanical advantage over ideal mechanical advantage
Thermodynamic efficiency, useful work per change in heat
Exergy efficiency, measure of 2nd-law themodynamic loss
Thermal efficiency, useful work per the higher heating value of the fuel
Efficiency (aerodynamics), for fixed wing aircraft the Lift-to-drag ratio
Efficiency (economics), a general term, to capture the amount of waste or other undesirable features
Pareto efficiency, making one individual better off, without making any other individual worse off
Kaldor-Hicks efficiency, like a less stringent Pareto efficiency
Allocative efficiency, an optimal distribution of goods
The optimisation of a social welfare function
Efficiency wages, paying workers more than the market rate for increased productivity
Efficiency (statistics), a measure of desirability of an estimator
Efficiency ratio, expenses as a percentage of revenue, etc.
Efficiency Movement, of the Progressive Era 1890-1932, advocated efficiency in the economy, society and government
Material efficiency, compares material requirements between construction projects or physical processes
Textual efficiency, density of a message
Algorithmic efficiency, the speed and space requirements of a computer program
Quantum efficiency, a measure of sensitivity of a photosensitive device: the percentage of photons hitting the photoreactive surface that will produce an electron–hole pair

hope this explains clearly to you what the word means.

Reading it for yourself is usually the best way to absorb the information . You can pick and choose what it best for you.

Answer 6

being effective without wasting time or effort or expense; "an efficient production manager"; "efficient engines save gas"

effective: able to accomplish a purpose; functioning effectively; "people who will do nothing unless they get something out of it for themselves are often highly effective persons..."-G.B.Shaw; "effective personnel"; "an efficient secretary"; "the efficient cause of the revolution"

Answer 7

efficiency is the ratio of output to input, i.e., a stereo which has an input power of 100W and a total output power of 90W would be ??% efficient.

Answer 8

It is a number that indicates how much of what you put into something that you are getting out. ie (Energy out)/(Energy in)

Answer 9

Not taking much energy or time.

Answer 10

doing something with the least amount of resources
