If you ask any computer authority roughly the vantage of electronic computer
use, two of their answers will be: The numeric result capability, and the tempo at which any mission is done.

There many more than advantages for mistreatment computers, but I will stress on the numeric computation feature of those advantages.

I have through with a examination involving numerical engineering science to trial the weight of my Central Processing Unit of my electronic computer. What I likewise did the experiment exploitation Windows Xp and Redhat Linux, which are both installed on the selfsame electronic computer.

One of the reasons why I did the test, that I am about to explain, was my wish to connotation the momentum of computer by looking at the silver screen.

Another principle was, I was acquiring fed up next to Hearing more or less computer specs, lacking even wise what they can do, or denote.

Here is an example:

Pentium II, 350 MHZ, Ram=256MB

Pentium III, 500 MHZ , Ram=512MB

and so on...

What is the driving force of the above specs?. How to inexact how many contemporary world the above P III is much vigorous than the P II?.

Here is what I did:

I nearly new my Pentium II, Ram=288MBs machine that has Windows XP and Linux installed on the aforementioned Hard disc in the identical information processing system.

I tested to use the peak numeral procedure clout of the electronic computer by testing to get the conclusion of multiplying the figure '2" by itself 99 modern times and both clip I got a result, I adscititious different "9" until the data processor can't handgrip the book anymore.

Using Windows Xp, I ran the machine by typewriting "calc.exe" in the Run box. Then, I used the experimental calculator to appendage the exponential computation.

The supreme I was able to reckon was 2 powerfulness 99,999. When I tested 2 last word 999,999, Windows XP resulted in an bloomer saying: "Invalid sign for function"

Then, I rebooted my computer, and picked Redhat Linux to run on the said computer or else of Windows Xp. Once Linux prompted me to login, I nearly new the algebraic inferior Linux has. It is named by typewriting "bc" at the tell stripe.

Once I ran "bc", I written 2^99,999, the same maximum digit I used in Windows Xp calculating machine . In nearly 2 seconds, i got the product.

Then, I tested a large number, 2^999,999 which Windows Xp medical calculating machine could not button. In roughly 5 seconds, I got the follow on the eyeshade. then, I supplementary one more integer to cypher 2^9,999,999 which is 2 multiplied by itself 10 Millions contemporary world minus one.

I waited in the order of 35 minutes, past Linux BC request make the phenomenon on the eyeshade by showing few screens loaded of numbers from left-handed to right, and
top to lower.

Now you likely thinking, how does this computing think to the celebration of the CPU, or the full-length electronic computer as a total.

Here is the answer:

What I discussed so far is mistreatment confident book to get the result of the guidelines 2 right 9,999,999. While moving the estimate victimization "bc" in Linux. in attendance another bid to track the running processes in genuine juncture.

So, as you are moving the calculations, you use other utility-grade called "top" in RedHat Linux.

Once you run "top", the system shows you on the projection screen a register of applications, next to all particulars something like the assets used-up for each. The detail is updated all few seconds, and each chain shows the given name of candidature.

So, to see the computing dramatization of "bc", you face up the procession that says "bc". Then, you outward show on the self procession that will exhibit you records nearly "bc" like:

1-the occurrence it is been running
2-The recall drinking in % of pure ram
3-How much CPU clout is man nearly new for the submission in %
and more variables.

You can study the surface for the updated occurrence the application
has been running for the circulating instant. Once the subtraction is conferred on the screen, you will cognise the addition is finished. You exterior at the time you only just taped matched earlier the contention finished.

The instance the request took to reckon the formula: 2^9,999,999 and the internal representation used, in amalgamation to the CPU muscle will pass you an approximative opinion roughly what your computing machine can do.

Also, you can use the preceding interview to likeness two computers and get and model astir the influence.

Here is an example:

If electronic computer P II, Ram=256Mbs took 30 minutes to compute 2^9,999,999; then, you ran the aforementioned audition 2^9,999,999 beside P III, Ram=512Mbs that took going on for 15 minutes, which is 1/2 the circumstance it took before.

Then, you can approximative that the quality of P III is astir twice over that of P II. Do, you get the idea?

In summary, in that is an assured way for you to investigate the dominance and ceremonial in forefront of you, true on the surface. I was able to do this project by victimization Linux, and Windows XP that are installed on the one and the same computer. I likewise saved out that Linux can do higher adding up that Windows Xp.

Thanks,
