OSBC - Binary Number System Lesson
Binary Number System
Computers do not process information like humans. Once data is input into a computer, the data is converted to binary code. Computers use switches to pass around electrical signals in binary code. The binary number system has two digits. Those digits include the numbers 0 and 1. Zero (0) represents off and one (1) represents on. When we count, we use the decimal system which consists of ten digits (0 - 9). After we reach nine, we move to the left one place and use a 1 to represent the 10's place. In the binary number system, you run out of digits sooner. To get to the next number, you must use the 0 as the placeholder and the 1 indicates one group of twos. View the video below to learn more about the binary number system.
