Hexadecimal is convenient because any group of four binary digits (a binary digit is also known as a bit) can be represented in one hexadecimal digit. This means that you can take a big binary number, break it into groups of four digits, and rewrite it in hexadecimal. For example,

The 1001 has been converted to 9 (see Table A-1), the 0111 has become 7, and so on. The 0x at the front is a notational convention indicating that the number is in hexadecimal. It s possible to think of that number as six 1s, fourteen 16s, six 256s, and so on. You start counting at zero and move from right to left, and each place represents the number of 16ns.

Using Bits and Bytes
If you put eight bits together, you have one byte. The word byte is simply the technical jargon for a group of eight bits. For example, 1001 0111 is a byte. It can also be represented as 0x97, so two hex digits make up one byte. The number 0x97 1D 86 E6 is 32 bits, or four bytes. A byte is also a measure of space. If your computer has 1MB of memory, that means it has space enough to load one million bytes of data into memory. A byte can have 256 possible values, from 0 to 255 (0x00 to 0xFF).
NOTE:
Actually, a megabyte is 1,048,576 bytes, which is 220. Most quantities of things in the computer industry come in powers of 2, either for technical reasons or simply because. Computers are binary machines, so hardware constraints may dictate that you use a power of 2, and in software, working with numbers that are powers of 2 can often be more convenient than using other numbers. But sometimes the only reason to use a power of 2 is that a task is being computerized. For example, in cryptography, 104-bit symmetric keys are secure enough, but that number is not a power of 2. So people use 128-bit keys. There s no technical cryptographic reason to use 128 bits instead of 104, but 128 is a power of 2. People working in computer science sometimes choose numbers simply because they are powers of 2.
Bits, Bytes, Hex, and ASCII
Using ASCII Characters
A computer chip can interpret only 1s and 0s and therefore does not have a native way to represent letters of the alphabet. So in the 1960s, at the beginning of the computer age, the American Standards Association, calling on the contributions of computer manufacturers, programmers, and others, came up with a standard way to represent letters as numbers. Because A is the first letter of the English alphabet, it could have been assigned the number 0x01; B could have been 0x02, and so on. It could have been, but that s not what the committee chose. The people involved were interested in representing more than just letters of the alphabet. They knew that computers would also need to interpret numerals, math symbols, and punctuation marks. In addition, they would need uppercase as well as lowercase letters. Eventually, a standard was developed specifying that the bytes 0x20 through 0x7F would be used to represent the English alphabet, numerals, certain symbols, and certain punctuation marks. That s 96 standard characters. Table A-2 shows the values and their characters. The standard is called ASCII (pronounced ASK-ee), an acronym for American Standard Code for Information Interchange. As it turned out, the original 96 ASCII characters were not sufficient because some languages had special marks on their letters (called diacritical marks), such as the umlaut (two dots) in or the cedilla (the squiggle on the bottom) in . Other languages had larger alphabets. In addition, values for more punctuation marks and control characters were needed. Over the years, standards committees have generated additional character sets. A byte can have only 256 possible values, and that is not enough space to hold all the possible characters. As a result, some of the new standards define characters in two bytes, allowing definition of as many as 65,536 characters. Other standards specify four bytes per character, giving space for more than four million characters. Most character sets include the original ASCII values along with the added values. All this means that if a computer is operating on the expression 0x52 53 41 53, it could be the hex representation of the decimal number 1,381,187,923, or it could be the letters RSAS.
