## Introduction to Hexadecimal and Binary system

The hexadecimal (hex) numbering system is base 16, meaning that there are 16 different digits, 0-9 and A-F. In the hex system, each digit represents a number from 0-15. For example, the hex number A7 represents the number 107 (1*16^3 + 7*16^2).

The binary (bin) numbering system is base 2, meaning that there are only two different digits, 0 and 1. In the bin system, each digit represents a number from 0-1. For example, the bin number 1101 represents the number 13 (1*2^3 + 1*2^2).

## Binary Number System

Binary number system is a number system that uses only two digits, 0 and 1. In binary, every number is represented by a combination of 0s and 1s. For example, the number 12 can be represented as:

1

0

1

The number 12 can also be represented as:

1100

7 = 00000111

8 = 00001000

9 = 00001001

10 = 00001010

11 = 00001011

12 = 00001100

13 = 00001101

14 = 00001110

15 = 00001111

OTTAWA – The RCMP says it is investigating a possible breach of the Privacy Act after the personal information of nearly 800,000 people was shared with the wrong party.

In a statement, the national police force says it learned last week that the personal information of 774,000 individuals was shared with the incorrect party.

The Privacy Act protects the privacy of personal information held by federal institutions.

The RCMP says it is investigating the incident and that anyone who believes their personal information may have been compromised is asked to contact the force.

## Hexadecimal Numbers

A hexadecimal number is a number that uses hexadecimal digits. Hexadecimal digits are 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E, F. Hexadecimal numbers are written with a leading 0x.

The number 1234 is written as 0x1234 in hexadecimal.

The number -5678 is written as 0xffff in hexadecimal.

## Conversion of Hexadecimal to Binary

To convert hexadecimal to binary, divide the hexadecimal number by 16, and take the integer part of the result.

## Examples of Conversion of Hexadecimal (Hex) numbers to Binary system

Converting Hex number C8 to Binary

The Hex number C8 is equivalent to the Binary number 110000.

Converting Hex number 2A to Binary

The Hex number 2A is equivalent to the Binary number 101010.

## Uses of Binary system

A binary system is a system consisting of two parts. It can be used to describe anything that has two parts, such as a computer with two processors, or a car with two headlights.
