Computers are everywhere. They are in people’s pockets, right on their wrists, in their cars, and maybe even inside a backpack. Many electronics including computers help us with manual work.

Just like other machines are designed to manipulate dirt or stone, computers need to be designed to manipulate information. Computers need to do four different tasks, for it to be a practical modern computer. They are, taking input, storing information, process everything it computed, and then give out the results, which would be the output. Computers still existed quite a few years before today. That time, computers were very different. They were made out of wood and metal. They also had mechanical gears and levers.

Computers first started as simple calculators, but at that time, they were awesome. All the input that goes into a computer, is stored in the computer’s memory, and then processed when it’s ready, and comes out as output when it has finished processing. A computer does it’s duties, only because of it’s algorithm.

A computer display can show text, photos, videos, games that are interactive and entertaining, and maybe some virtual reality videos/episodes.

But how do computers work?

The whole reason computers actually work, are because of their binary code. It’s binary code is made up of just ones and zeros, but those simple ones and zeros control everything the computer does, from typing on your keyboard all the way to creating a website.

A one can represent yes, on, true, or anything positive like that. A zero can represent no, off, false, or anything negative like that.

Binary code’s ones and zeros in a computer can be manipulated into values, for the same thing. Ones, zeros, and other numbers too, although other numbers are not normally used in binary code. For example, for the alphabet, 1 could be A, 2 could be B, 3 could be C, 4 could be D, and so on.

Based on binary code, if you were to write the word “Cat”, it would be 3119. That’s because C is the third letter, which would make the 3 part, A is the first letter, which would make the one part, and T is the nineteenth letter, which would make the 19 part. Put them all together, and you get 3119. But, 3119 can’t be binary code, since it has more than just ones and zeros. So, the computer will have to convert it all into ones and zeros by doing some specific math equations.
