Computers operate by using millions of electronic switches transistors , each of which is either on or off similar to a light switch, but much smaller. The state of the switch either on or off can represent binary information, such as yes or no, true or false, 1 or 0. The basic unit of information in a computer is thus the binary digit , or bit.

Although computers can represent an incredible variety of information, every representation must finally be reduced to on and off states of a transistor. Let's start with representation of numbers, perhaps the simplest information to represent in a computer. When you see the string of digits , you most likely interpret this as "one thousand two hundred ninety-seven. More formally, we could write the string as: Notice that each place to the left represents a higher power of 10 the base.

Binary numbers work similarly, but with 2 as the base. For example, the string in binary is interpreted as follows: Another example is , which is interpreted as: Using binary numbers, we can store any whole number in the computer, as long as we have enough transistors switches to represent all the bits.

Many microprocessors use 32 bits to represent numbers, which means they can store any value from 0 up to 4,,, If larger numbers are needed, then more switches must be used to represent the additional bits. Let's count, starting from 1 in both base and base In base, there are ten digits 0 through 9 and after these are used, a new place the 10s place must be added to the left.

In base-2, there are two digits 0 and 1 , after after these are used, a new place the 2s place must be added to the left. The right-most column alternates 0, 1, 0, 1, 0, 1. The next column alternates two 0s and then two 1s: The next column alternates four 0s and then four 1s, and so on.
