How Computers Store Information
Eight bits together are called a “byte.” You might heard this term before. The size of a computer or device’s storage is often measured in “gigabytes,” a term that means means billions of bytes.
You can see a representation of 8 bits by using these online binary cards.
What do you notice about these images? Each one has a different number of dots and those dots are in a pattern. Can you tell what the pattern of the sequence of cards is?
Here’s a hint: If we added another image, it would have 256 dots.
Each of these images has double the number of dots as the one on its right. Using these images, you can make any number, you just need to use the right ones. In this case, we can turn a bit “on” by showing the dots. If you click on a card, it will turn “off” and show nothing. Just like 1s and 0s, we can say “on” and “off” are binary.
Turn all of the cards “on”. How many dots are showing?
In this case, a card that is off is a 0, and a card that is on is a 1. So the byte can represent 255 by using binary digits as 11111111.
