## Why do computers use hexadecimal?

Hexadecimal numerals are widely used by computer system designers and programmers because they provide a human-friendly representation of binary-coded values. Each hexadecimal digit represents four bits (binary digits), also known as a nibble (or nybble), which is 1/2 of a byte.

Hexadecimal is useful because large numbers can be represented using fewer digits. For example, colour values and MAC addresses are often represented in hexadecimal. Programmers often use hexadecimal to represent binary values as they are simpler to write and check than when using binary.

## What does F mean in hexadecimal?

Hexadecimal uses the decimal numbers and six extra symbols. There are no numerical symbols that represent values greater than nine, so letters taken from the English alphabet are used, specifically A, B, C, D, E and F. Hexadecimal A = decimal 10, and hexadecimal F = decimal 15.

## Where is hex used?

Hex is often used in error messages on your computer. The hex number refers to the memory location of the error. This helps programmers to find and then fix problems.

## What are hex codes?

Hex codes are a hexadecimal format for identifying colors. This is a system used in HTML, CSS and SVG. Each hex code refers to a very specific color, which allows for two designers or a designer and developer to be on the same page about what exact light blue (or any other color) they are referring to.

## Is MAC address a hex?

MAC Address is a 12-digit hexadecimal number (6-Byte binary number), which is mostly represented by Colon-Hexadecimal notation. First 6-digits (say 00:40:96) of MAC Address identifies the manufacturer, called as OUI (Organizational Unique Identifier).

## What is 48 bit address?

A 48-bit memory address can directly address every byte of 256 terabytes of storage. 48-bit can refer to any other data unit that consumes 48 bits (6 octets) in width. Examples include 48-bit CPU and ALU architectures are those that are based on registers, address buses, or data buses of that size.
