Would you believe that computer can get the average of a million sets. of numbers in a few
seconds by pressing a button? It is like getting the sum or total of one hundred different sets of
numbers in one click.
2. The computer gives accurate results.
Some scientists use the computer in their experiments. The needed data for their experiments are
processed in the computer. They can get almost perfect and more accurate results through it.
3. The computer stores large amount of data and information.
Most computers have storage or accessories wherein the user can save information or document.
These are called floppy diskettes, hard disks and zip disks.

you what you ask it.
2. It cannot generate information on its own.
Your computer depends on you. It will not run unless you operate it. In the same way, it cannot
give you information you need if you do not feed it with the necessary data.
3. The computer will give you wrong information if you feed it with wrong data.
The computer cannot distinguish between correct data and wrong data. Thus, if you feed your
computer with wrong data, it will result with the computer giving wrong information.
