Graphical Approach to the Learning of Inter-conversion of Various Number Systems
The number is a symbol or a word used to represent a numeral, while
a system is a functionally related group of elements, so as whole, a
number is set/group of symbols to represent numbers/numerals. In
other words, any system that is used for naming or representing
numbers is a number system, also known as numeral system. Almost
everyone is familiar with decimal number system using ten digits.
However digital devices and computers use binary number system
instead of decimal number system, having only two digits i.e. 0 and
1. Binary number system is based on the same fundamental concept
of decimal number system. Various other number systems also use
the same fundamental concept of decimal number system, e.g. octal
number system (using eight digits) and hexadecimal number systems
(using sixteen digits). The knowledge of number systems, their
limitations, data formats, arithmetic, inter conversion and other
related terms is essential for understanding of computers and
successful programming for digital devices. Understanding all these
number systems and particularly their inter conversion (such process
in which things are each converted into the other) of number system
requires allot of time and a large number of techniques to expertise.
In this particular paper the intercom version of four well-known
number systems is taken under the consideration in tabulated as well
as graphical form. It is simply a shorthand to the inter conversion of
these number systems to understand as well as memorise it. The
well-known number systems to be discussed are binary, octal,
decimal and hexadecimal.
