Efficiency and effectiveness are often confused. Efficiency is the ratio of output to the input of a process. Always less than 100%. We may consider the power output of an engine compared with the power input needed for that output.
Effectiveness is the usefulness of the output, compared to the costs (price - energy - complexity etc) of the process. For example, there are several methods for obtaining say the square root of a number, but some will be more complex than others. These are less effective, even though they produce the same answer.

There are programs advertised that "improve" your computer's performance, however, most of these do nothing to really help.
A high efficiency machine will produce more of what is it that you want with the same power as the low efficiency one. In other words, for a low efficiency machine do as much as a high efficiency one, you have to give it more power (energy).
B.) efficiency
2%
friction or The mechanical advantage is greater for thinner wedges. However, the efficiency is low because of the large amount of friction.
That amount is always less than the energy you put into the system. Divide the amount of useful energy you get from a system by the amount of energy you put into it, and you find the system's 'efficiency'.
Efficiency
Algorithms are the foundation of computer Science, it is telling the computer to do the task in the most efficient matter. An algorithm is particularly important in optimizing a computer program, the efficiency of the algorithm usually determines the efficiency of the program as a whole.
Efficiency=Ratio of actual speedup to the maximum speedup =speedup/length of pipeline
Cost Effectiveness Efficiency Reliable
You will most likely use a computer in graphics. It will make it much easier for you and probably improve your efficiency.
improve efficiency , accuracy , and to reduce workload
In Networking It means the transmission of data from one computer to the other with minimum or no errors
Most computer power supplies contain both. The transformers are usually toroidal transformers for high efficiency and compactness.
This is a major source of efficiency because once the information is updated, everybody who is online get the information right away their not a second hand information.
for improving the efficiency of the computer system.In multiprocessor environment , instructions can be executed parallely.
The computer is very important in a given economy sector because it is efficient and very accurate. A computer helps cut the costs in a given economy by performing tasks in a high degree of efficiency.
They can help increase accuracy and efficiency and decrease time wasted and errors.
