Notes

Decimal and Binary Number

The number of base or radix ten is called decimal numbers. Similarly, Binary Number is a number of two base numbers.This note provides an information about Decimal and Binary Numbers.

Octal Number System

The number with base eight is called octal number. We can generate these numbers with the combination of 0, 1, 2 3, 4, 5, 6, 7. This note provides an information about Octal Number System and its conversions.
