Detailed explanation-1: -The need for hexadecimal numbers The format of hex numbers is more compact than binary numbers because they can represent large binary numbers with fewer digits. As a result, they are easier to understand than long binary strings of 1s and 0s.

Detailed explanation-2: -Although most humans are familiar with the base 10 system, it is much easier to map binary to hexadecimal than to decimal because each hexadecimal digit maps to a whole number of bits (410).

Detailed explanation-3: -Binary and Hexadecimal number systems are examples of positional number systems with different bases. Binary number systems use a base of two while hexadecimal uses a base of 16. In a hexadecimal system, it is necessary to count to 15. To represent the numbers 10 – 15, the letters A – F are used respectively.

Detailed explanation-4: -Hexadecimal, also known as hex, is the third commonly used number system. It has 16 units (0-9) and the letters A, B, C, D, E and F. Hex is useful because large numbers can be represented using fewer digits. For example, colour values and MAC addresses are often represented in hex.
