Here you ve seen a number of ways in which security can be ensured through the use of existing standards, protocols, algorithms, and assistance from consultants who have been shown to be of great help. Through the certification process, many users can ensure that their security methods (especially cryptography) are as well designed and well implemented as possible. It is sometimes useful to consult with a trusted third party or external agency to gain a different point of view. Security is an important issue for businesses and other organizations that are entrusted with personal data. In the long run, everyone benefits when consumers can have faith in the technology that enables not only the efficient storage of data, but also the potential for unprecedented communication and human growth.

Throughout this book, we show data as hexadecimal (often shortened to hex ) numbers. Even if the data is a series of letters, it can be represented in hexadecimal numbers. This appendix describes bits, bytes, and hexadecimal numbers and explains how ASCII characters are formed.

Data Matrix Printer In Visual Basic .NET Using Barcode encoder for .NET framework Control to generate, create DataMatrix image in Visual Studio .NET applications. A computer is a binary machine; everything is either on or off, reflecting the fact that electric power is either flowing or not flowing through a given circuit. The machine can be programmed to interpret the state of being on or off as a 0 or a 1. If you string these 0s and 1s together, you can represent anything. For example, you can represent the decimal number 105 as the binary number 1101001. To see how binary numbers work, it might be helpful to recall how decimal numbers work. A decimal number is composed of some number of ones, tens, hundreds, and so on. As Figure A1 shows, if you start Generate Linear 1D Barcode In Java Using Barcode encoder for Java Control to generate, create Linear 1D Barcode image in Java applications.

The number 8,614 is decimal, comprising four ones, one ten, six hundreds, and eight thousands. The number 10000110100110 is the binary equivalent. The numerals in the positions indicate the number of powers of 1, 2, 4, 8, and so on counting at zero and move from right to left, each place in a decimal number represents a number of 10ns (10 to the nth power). A computer does the same thing except that it uses two as its base instead of ten. For each place in a binary number, there can be only two possible values: a 0 or a 1. In Figure A1, the binary number is computed if you start counting at zero and move from right to left to see how many ones, how many twos, how many fours, and so on, each of which represents a power of 2. Any value that can be represented as a decimal number can also be represented as a binary number. The binary number will take up more space, but any value can be expressed. Suppose you wanted to use the decimal number 2,535,294,694. A computer would think of it as binary, which would look like this: 1001 0111 0001 1101 1000 0110 1110 0110 Writing such numbers can be tedious, so programmers use hexadecimal as a convenience. The word decimal has to do with ten ( dec means ten, as in decade or decathlon ), whereas binary refers to two ( bi means two, as in bicycle or bifocals ), and the word hexadecimal refers to sixteen. So binary numbers are base two, decimal Bits, Bytes, Hex, and ASCII
numbers are base ten, and hexadecimal numbers are base sixteen. The digits used in binary numbers are The digits used in decimal numbers are
0 1 2 3 4 5 6 7 8 9 And the digits used in hexadecimal numbers are
0 1 2 3 4 5 6 7 8 9 A B C D E F
Notice that each system has the same number of digits as what we ve referred to as the base. Base two uses two digits, base ten uses ten digits, and base sixteen uses sixteen digits. Table A1 is a conversion table for numbers in the three bases.
