                 A computer takes data from a user and produces result as information. Although the words data
                 and information are often used interchangeably, but there is an important distinction between

                 the two words. In the strict sense, data consists of the raw facts that computers organise to
                 produce information.
                 From an early age, we are introduced to the concept of numbers and counting. Toddlers learn at
                 an early age that they can carry two cookies, one in each hand. Kindergarteners start counting by
                 twos and fives. Invariably, we use the decimal number system. Our number system is based on
                 10, most likely because we have 10 fingers. Let us learn more about the number system.

                       The numerical digits we use today, such as 1, 2, and 3, are based on the Hindu-Arabic
                      numeral system developed over a thousand years ago.
                       The number 0 is known by various names, including zero, nought, naught, nil, zilch, and
                      zip.



                     WHAT IS NUMBER SYSTEM?

                 A Number System is simply a method of counting. There are many number systems in existence.
                 Consider a clock. Clocks have 24 hours, each hour has 60 minutes. Each minute is in turn has
                 60 seconds. When you learnt to count, you used the numbers, like 1, 2, 3, etc. Similarly, computers

                 also have their own number system, known as the binary number system.
                 The digital computer represents all kinds of data and information like audio, graphics, video, text
                 and numbers in binary form.
