Briefly describe the hexadecimal numbering system.
What will be an ideal response?
The hexadecimal numbering system is base 16; in other words, 16 numerals are used to express any given number. These numerals include 0 through 9 as well as A through F. Because more numerals are available in hexadecimal, it is logical that any given number can be expressed with fewer hexadecimal numerals than with either binary or decimal. For example, the decimal number 192 is C0 in hexadecimal.
Why should you be concerned with hexadecimal numbering? Often you will come across hexadecimal numbers when working with computers and networking. For example, the MAC address is a 12-digit hexadecimal number. Another example is the color displayed on your TV and computer monitors. The colors are coded using two-digit hexadecimal numbers. Another common use of hexadecimal numbering occurs in packet sniffing. Sniffers placed on the network to capture packets usually display much of the capture information in hexadecimal. In addition, memory addresses are displayed in hexadecimal. Most importantly, computers typically process information in 8-bit chunks (bytes). It is easier to express those eight bits with two hex digits.
