**hex**triplet is a six-digit, three-byte**hexadecimal**number**used in**HTML, CSS, SVG, and other computing applications to represent**colors**. The bytes represent the red, green and blue components of the**color**. One byte represents a number in the range 00 to FF (in**hexadecimal**notation), or 0 to 255 in decimal notation.A.

### What are the advantages of using hexadecimal numbers?

The main

**advantage**of a**Hexadecimal Number**is that it is very compact and by using a base of 16 means that the**number**of**digits**used to represent a given**number**is usually less than in binary or decimal. Also, it is quick and easy to convert between**hexadecimal numbers**and binary.#### What does 0x mean?

In C and languages based on the C syntax, the prefix**0x**means hexadecimal (base 16). Thus, 0x400 = 4×(16^{2}) + 0×(16^{1}) + 0×(16^{0}) = 4×((2^{4})^{2}) = 2^{2}× 2^{8}= 2^{10}= 1024, or one binary K.#### What do you mean by BCD?

Binary coded decimal (**BCD**) is a system of writing numerals that assigns a four-digit binary code to each digit 0 through 9 in a decimal (base-10) numeral. The four-bit**BCD**code for any particular single base-10 digit is its representation in binary notation, as follows: 0 = 0000. 1 = 0001. 2 = 0010.#### What are the advantages of using hexadecimal numbers?

### What is the hexadecimal system used for?

Hexadecimal numerals are widely used by computer system designers and programmers, as they provide a more human-friendly representation of binary-coded values. Each hexadecimal digit represents

**four**binary digits, also known as a nibble, which is half a byte.#### What are hex code used for?

**Hexadecimal**is the easiest way to write down binary**numbers**in a compact format. One**important**reason is because hex is ALOT shorter and easier to read than binary is for humans.**Hexadecimal number**is very easy to convert the**numbers**into binary, octal,and decimal**system**also.#### Who invented the hexadecimal system?

Hex, short for "hexadecimal base counting", was invented in France in the year 770 AD. In that time**Mervin**, a famous wizard, became a counselor to King**Charlemagne**because he had 8 fingers on each hand.
