Therefore, the examples above would be shown as 0x0A and 0x73 respectively. However, because subscript text is not recognized in command line or programming environments, the technical representation of hexadecimal is preceded with '0x' (zero X). Less commonly, it may be followed by an H, for example 73H. Hexadecimal is usually represented in text by the value preceded by 0x (for example 0x73) or a subscript 16. Note: It is important to distinguish hexadecimal values from decimal values regarding the characters 0 to 9, as shown in Figure 1. For example, the binary value 0000 1010 is shown in hexadecimal as 0A. Leading zeroes are always displayed to complete the 8-bit representation. Given that 8 bits (a byte) is a common binary grouping, binary 00000000 to 11111111 can be represented in hexadecimal as the range 00 to FF. It is easier for us to express a value as a single hexadecimal digit than as four binary bits. Figure 1 shows the equivalent decimal and hexadecimal values for binary 0000 to 1111. The base sixteen number system uses the numbers 0 to 9 and the letters A to F. Just as decimal is a base ten number system and binary is a base two number system, hexadecimal is a base sixteen system. Hexadecimal provides a convenient way to represent binary values. When used by itself (as a noun) it means the hexadecimal number system. Hexadecimal is a word that is used both as a noun and as an adjective. The use of the MAC address is one of the most important aspects of the Ethernet LAN technology.
