Applying Conversions

There are several types of numbering conversions that you need to be able to perform. It's not that you'll be doing this on a day-to-day basis, but you need to understand the concepts, especially as the decimal-to-binary conversions apply to IP subnetting.

Specifically, the conversions you are going to learn are as follows:

• Decimal-to-binary conversion
• Hex-to-decimal conversion
• Binary-to-hex conversion

Decimal-to-Binary Conversion

Converting a decimal number to binary, and vice versa, is an important concept for IP addressing. As you will learn in Chapter 8, subnetting that departs from classful subnetting is done on the binary level and requires an understanding of decimal-to-binary conversion. We are going to approach ...
