How do I explain what is data structure to someone who has never programmed before?
In: 15
Computers are machines that use electricity to represent information. At its most basic, this information is just numbers.
Computer storage/memory therefore is just a big bucket of numbers. Numbers, text, images, audio, programs/instructions, all this data is just numbers. Without anything to give them context, all you have is a bunch of random-looking numbers.
Data structure is the way we give structure and meaning to those numbers so they can be used in the most efficient way for the task at hand.
