The second lesson is an introduction to the binary numbering system. This section will cover why we use this numbering system and provide practice problems converting binary numbers to decimal numbers and vice versa.

People use the decimal numbering system which uses the digits 0 through 9. Computers use the binary numbering system which uses the digits 0 and 1. Details of each numbering system will be discussed in this lesson as well as sample conversion problems. I highly recommend that you go to the practice problems link on the home page and do the binary conversion practice problems. There is an answer link on that page so you can check your answers. For more conversion problems click on the calculator link on the home page and then click on calculator 1. A firm understanding of the binary numbering system will help make subnetting much easier to learn.
