For instance, in the following hex dump, each 8-bit byte is a 2-digit hex number, with spaces between them, while the 32-bit offset at the start is an 8-digit hex number. 00000000 57 69 6b 69 70 65 64 69 61 2c 20 74 68 65 20 66 00000010 72 65 65 20 65 6e 63 79 63 6c 6f 70 65 64 69 61 00000020 20 74 68 61 74 20 61 6e 79 6f 6e 65 20 63 61 6e ...
Hexspeak is a novelty form of variant English spelling using the hexadecimal digits. Created by programmers as memorable magic numbers, hexspeak words can serve as a clear and unique identifier with which to mark memory or data. Hexadecimal notation represents numbers using the 16 digits 0123456789ABCDEF.
The remainder gives the second hexadecimal digit. For instance, the RGB value 58 (as shown in the previous example of hex triplets) divides into 3 groups of 16, thus the first digit is 3. A remainder of ten gives the hexadecimal number 3A. Likewise, the RGB value 201 divides into 12 groups of 16, thus the first digit is C.
Although there is no official standard, today most devices displaying hex digits use the unique forms shown to the right: uppercase A, lowercase b, uppercase C, lowercase d, uppercase E and F. [5] To avoid ambiguity between the digit 6 and the letter b the digit 6 is displayed with segment A lit. [2] [6] [7] [8] [9]
where nnnn is the code point in decimal form, and hhhh is the code point in hexadecimal form. ... 8 56 070 Digit Eight: 0025 U+0039 9 57 071 Digit Nine: 0026 ASCII
That is, the value of an octal "10" is the same as a decimal "8", an octal "20" is a decimal "16", and so on. In a hexadecimal system, there are 16 digits, 0 through 9 followed, by convention, with A through F. That is, a hexadecimal "10" is the same as a decimal "16" and a hexadecimal "20" is the same as a decimal "32".

8-bit color graphics are a method of storing image information in a computer's memory or in an image file, so that each pixel is represented by 8 bits (1 byte). The maximum number of colors that can be displayed at any one time is 256 per pixel or 2 8 .
