Computer Numbering System

Human and computers have different ways of identifying , counting and manipulating  a number .

Identifying and counting a number by human varies from simple to complex

Suppose you are  to find the total numbers of students in a class,  you start by counting 1 ….. n and not n …. 1

 

Simply because , the the last number ( n ) of the student  is unknown. Similarly computers have a specific way of identifying, counting and manipulating number

Four types of computers numbers

  1. Decimal
  2. Binary
  3. Octary
  4. Hexa decimal

In this post , I will be explaining the basic applications and  ways of manipulating these numbering in every day activitie

Number Type          Values                            Base

Decimal :            0 ... 9                         | base of 10

Binary :             0 and 1                         | base of 2

Octary :             0 - 7                           | base of 8

Hexa decimal :       0 ... 9 - A ... F               | base of 16
