🧠 What is the number 0, 1 in a computer?

🧠 What is the number 0, 1 in a computer? Why does the digital world only have these two?

Have you ever wondered why the information, pictures, videos, music or text that we see on the computer screen is made up of just these two numbers 0 and 1? Today we're going to unravel the secrets of the digital world.

Compare 0 to 1 with "light switch."

To explain it as easily as possible, think of a light switch in our home:

* 1 (on): means there is electricity flowing through or "on."

* 0 (off): means no electricity; or "off"

Computer systems also work on the same principle, using billions of "electronic circuits" that can be turned on or off, "on" instead of 1, and "off" instead of 0.

How do 0 and 1 generate data?

Each of the numbers 0 and 1 is called a bit, which is the smallest unit of data in a computer. When multiple bits are arranged, more complex data can be generated:

* 8 bits = 1 byte (Byte): For example, the letter "A" in a computer system is represented by a binary code consisting of 8 bits.

* 1024 bytes = 1 kilobyte (KB): It can store data equal to about 1 page of plain text.

* 1024 kilobytes = 1 megabyte (MB): Can hold 1 picture or 1 song

You can see that these 0 and 1 numbers are not alone, but are combined into a series of data that we use every day.

Conclusion

So 0 and 1 are like the basic "language" that computers use to communicate and process everything from letters, images, to videos we watch on YouTube. Next time, look at your computer and think about the millions of tiny light switches that are running.
