Question

Write different applications where we can use Hexadecimal to represent data.

(a) Image processing
(b) Cryptography
(c) Color representation
(d) All of the above

Answer 1

Hexadecimal notation is used in image processing to define pixel colors, in cryptography for keys and hashes, and in color representation for web and graphic design. All listed options are correct uses of hexadecimal.

Step-by-step explanation:

In different applications, hexadecimal notation is used to represent data, including:

• Image processing: Hexadecimal is often used to specify pixel colors in digital images, where each color channel (Red, Green, Blue) is typically represented by a pair of hexadecimal digits.
• Cryptography: Hexadecimal can be used to display binary data in a more readable format, especially in the context of encryption keys and hashes.
• Color representation: In web design and graphic software, colors are commonly represented as hexadecimal codes, where the codes specify the intensity of red, green, and blue in a color.

All the options listed above: (a) image processing, (b) cryptography, and (c) color representation, are valid applications where hexadecimal notation is applicable and widely utilized. Hexadecimal provides a compact and human-readable way to express large binary numbers, which is why it's so prevalent in these fields.
