Therefore, using the smallest amount of memory for a value (one byte) offers a range of 0 - 255. Since a byte can thus contain eight ones or zeroes, the largest value a byte can represent with all eight bits filled with ones (11111111) equals 255. Whereas a bit represents a single 1 or 0, a byte represents eight bits. To recap, a computer counting from zero to five looks like 0, 1, 10, 11, 100, 101. Lastly, a 1 in both the fours and ones places (101) equals five. A 1 in the fours place (100) equals four. A 1 in both the ones and twos places (11) add together to equal three. A 1 in the twos place and a zero in the ones place (10) equals two. instead of ones, tens, hundreds, places.Īnalyzing how a computer counts to five illustrates this concept. Since a binary digit can only represent one of two values, counting in binary uses a ones place, a twos place, a fours place, an eights place, a sixteens place, etc. In that base 10 example, the 3 in the ones place, the 2 in the tens place, and the 1 in the hundreds place combine to represent the number one-hundred twenty-three. Though a single bit can only represent 0 or 1, multiple bits can be combined to represent larger values, just as the single digits 1, 2, and 3 can be combined to represent the number 123 in the base 10 decimal counting system we typically use outside of the context of programming. Memory at its most basic form consists of the binary digits 0 and 1 where a single one of those digits is referred to as a bit. The scale relates to computer memory and it's used instead of a percentage to allow young users to gain familiarity with how computer memory works.
