Three combinations generate a 0, and one combination generates a 1. The AND operation is used extensively with IP addressing and subnet masks. Table 1-8 AND Operation AND 0 1 0 0 0 1 0 1 The OR operation, as shown in Table 1-9, also takes two input values. If one value is 1 or both values are 1, the output is 1.

The seventh position to the left represents 106 (10 × 10 ∗ 10 ∗ 10 ∗ 10 ∗ 10 = 1,000,000). This is true no matter how many columns the number has. For example: 2134 = (2 ∗ 103) + (1 ∗ 102) + (3 ∗ 101) + (4 ∗ 100) There is a 4 in the ones position, a 3 in the tens position, a 1 in the hundreds position, and a 2 in the thousands position. This example seems obvious when the decimal number system is used. Seeing exactly how the decimal system works is important, because it is needed for you to understand two other number systems, binary (Base2) and hexadecimal (Base16).
