Hexadecimal in Computing

Hexadecimal is widely used in computing for several reasons:

• It provides a more compact way to represent binary data (each hex digit represents 4 binary digits)
• It's used for memory addresses in programming and debugging
• It's used for color codes in web design (e.g., #FF5733)
• It's used to represent MAC addresses and other hardware identifiers

Why is hexadecimal used instead of decimal in computing?

Hexadecimal is used because it provides a more compact and readable way to represent binary data. Since 16 is a power of 2 (2^4), each hexadecimal digit precisely represents 4 binary digits, making conversion between binary and hexadecimal straightforward.

How are hexadecimal numbers denoted?

Hexadecimal numbers are often prefixed with "0x" (in programming languages like C, Java, and JavaScript) or "#" (in web colors). For example, 0x1A3 or #1A3.

How do hexadecimal colors work?

In web design, colors are often represented as 6-digit hexadecimal numbers, where the first two digits represent the red component, the middle two represent green, and the last two represent blue. Each pair ranges from 00 (no color) to FF (full color). For example, #FF0000 is pure red, #00FF00 is pure green, and #0000FF is pure blue.
