Answer:The binary number system is the fundamental way computers and all digital devices work. Unlike the decimal system we use daily (which has a base of 10 and uses digits 0-9), the binary system has a base of 2 and uses only two digits: 0 and 1.Every piece of data—whether it's text, an image, or a video—is translated into long sequences of 0s and 1s, which are called "bits." This system works perfectly for computers because it's easy to represent physically using electrical switches that are either on (1) or off (0).
