Day 40: Number System

Hello Dear Students,
Hope you all are doing good..

Aaj hum computer number system ke baare mein study karenge,

So, let's get started....
  • Computer system ki language Binary language hoti hai.
  • Binary Language means 0s and 1s.
  • User jo bhi input deta hai, computer usse binary form mein convert karke processing karta hai, because computer system can understand only 0s and 1s. 
  • So, hum discuss karenge binary numbers ko.
Decimal Number             Binary Number Explanation  
 0    0 Since we take only 0 and 1, so first comes 0
 1 1 Now, the next of 0 is 1, so here value of decimal no 1 is 1
 2 10After 1, there is 10 in which 0 and 1 comes,
because from 2 to 9, there is no 0 and 1. 
 3 11After 10, 11 has 0 or 1.which is 11. 
 4 100After 11, there is only 100 which is 0 and 1s.
 5 101 Next is 101,thus 5 is stored in computer as 101.
 6 110 Next is 110,thus 6 is stored in computer as 110.
 7 111 Next is 111, thus 7 stores in computer as 111.
 8 1000 After 111, there comes 1000, where 0 and 1 comes.
 9 1001 Next is 1001, thus 9 is stored in computer as 1001.

  • BINARY NUMBER SYSTEM
  • Basically jis numbers mein only 0 and 1 hon, wohi binary numbers hote hain.
  • The number of digits in binary numbers are two(0 and 1), which are known as Bits.
  • The base is 2.
  • DECIMAL NUMBER SYSTEM
  • Decimal numbers are basic which we use in our daily life.
  • The digits in decimal numbers are- 0,1,2,3,4,5,6,7,8,9.
  • The base is 10.
  • OCTAL NUMBER SYSTEM
  • Octal numbers are the numbers with base 8.
  • The number of digits are- 8 (0,1,2,3,4,5,6,7).
  • Counting sequence is - 0,1,2,3,4,5,6,7,10,11,12,13,14,15,16,17,20,21,...so on.
  • HEXADECIMAL NUMBER SYSTEM
  • Hexadecimal numbers are the numbers with base 16.
  • The number of digits are - 16 (0,1,2,3,4,5,6,7,8,9,A,B,C,D,E,F).
  • A,B,C,D,E,F are equivalent to decimal numbers 10,11,12,13,14, and 15 respectively.

Next, we will discuss about the conversions.
