What is the binary system
What is the binary system?
The word "binary" describes a system that has only two possible digits. To understand this, let's first compare this to a system you're probably more familiar with, the Decimal system.
The word "decimal" describes a system that has ten possible digits. These are the digits 0 through 9. Every number expressed in the decimal system is a combination of these ten digits. You use the decimal system every day, it comes naturally, we all have 10 fingers and 10 toes (unless your family tree doesn't fork, but let's not go there), and some of us use those 10 fingers and toes extensively to help with every day addition and subtraction.
The binary system works essentially the same way, with the only difference that it only has two digits. These are visually expressed by the digits 0 and 1. Every number expressed in the binary system is a combination of these two digits.
