### 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 10 After 1, there is 10 in which 0 and 1 comes, because from 2 to 9, there is no 0 and 1. 3 11 After 10, 11 has 0 or 1.which is 11. 4 100 After 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.
