Jack, a genius, built a Time Machine. Unable to find anybody to test it on, he decided to test the time machine himself. He entered the machine and set it to the future year 2355. Lights flashed, the super generator started and the machine started time travel, for the first time ever.
When everything became normal again, he stepped out of the time machine and noticed the following things:
I) There were so many trees, so many that you can’t spot the ground.
II) There was 1 river.
III) There were nearly 200-400 “Dodo” birds in that area.
IV) There were 0 people to be seen anywhere.
All the things that he observed are-
data
Data is a collection of facts and figures. It can be numbers, words, pictures or even just an observation.
