what is number system?

in the number system basically of two types:

1. 1st is non-positional number system
2. 2nd is positional number system

• =>non-positional number system

in early days ,human beinds counted on fingers.when 10 fingers were not adequate,stones,pebbles,

or sticks were used to indicate values.
this method of counting uses an additive approch or the non postional number system.
in this number system we have symbols such as I,II,III and so on.since it is very difficult
to perform arithmetic with such a number system.
positional number system were developed as the centuries passed.

• =>positional number system

in a positional number system, there are only a few symbols called digits, and this symbols
represents diffrent values depanding on the position they occupy in the number.
the value of each digit in such a number is determined by three consideration.

• the digit itself
• the position of the digit in the number
• the base or radix of the number system (where base is defined as the total number of the digits available in the number system.
  

the number system that we are using in our day to day life is decimal number system which has
been based at 10.basically there are 4 type of positional number system

1. binary number system.
2. octal number system.
3. decimal number system.
4. hexa decimal number system.
   

computer is only know binary number system which is also called machine level language.
some of the number system commonly used in computer science and by computer professional
are discussed at the next blog.
