In this lesson, we'll be introducing binary numbers, bits, and bytes. Humans use what's called Base 10 arithmetic: we count from 1 to 10, restarting and adding a place value when we run out of fingers. Computers don't have fingers though. They have electricity!An electrical current is either flowing, or not flowing: two states. This can be represented by either a 1 (on) or a 0 (off). Using ones and zeros, computers can write every number we use in Base 10. Numbers that use only 1s and 0s are in Base 2, or binary. |
