Whereas we think of number as being expressed in Base 10, Decimal or Denary using digits 0-9 it’s much easier for computers to work with just two numbers 0 and 1. These two numbers can represent a transistor or microscopic switch in the computer which turns on and off as electricity flows through it. When these series of 0 and 1 are put together they can form the basis of all data and information contained on the computer from text to image s to music and videos.
In base 10 we use something called place value so that the same digit can represent different values of numbers.
The table above represents the number 2395 in base 10 or 239510
