Now we come to the categories of the number system. What are the different categories? The first one which I showed you, it was decimal, the most popular one. Then it comes most important one in computer system, this binary. Then octal and hexadecimal. So these are the four categories of number system. So let us discuss one by one, what are they? As we know decimal number system has 10 unique or distinct digits represented by 0, 1, 2, 3, 4, 5, 6, 7, 8 and 9. So the base or radius of the system is 10. For better understanding, let us take an example, suppose it is a decimal number 453. So what we know, this first one is known as unit position. Second one is the 10th position and this third one is the 100th position. How this come? Because the base of this decimal system is 10, this is the base. So from when we come to towards left, it increases by a proportion of 10. So how we write this 450t, actually this is represented as 4 into, as it is a second place, 10 square 5 into 10 to the power 1 plus 3 into 10 to the power 0. So this is the breakup of the system and when we specifically define the decimal number system, so we have to write the base. Now we come to the binary number system. In binary number system, there are only 2 digits that is 0 and 1. Whole system is, number system is defined using 0 and 1 and in this system the base or the radius is only 2. So next we come to the octal number system. It is also a most commonly used positional number system and in octal number system, it uses only 8 digits. It seems similar to the decimal number system but in decimal number system, we had the number from the ranging from 0 to 9. But here only it, it considers only 8 digits and it is up to 7. So what is its base? Its base is 8. If we consider any number and I write here base as 8, this represents an octal number and how we break them. This way we can break them. If we solve this, this will not remain 253. The result will come as decimal number. Now one important thing, in this number 253, it is applicable to the odd number system. In this number 253, here the 2 is phase value and this one that means h square or 8 to the power 1 or 8 to the power 0, whatever it is, this is the known as phase value. This is common to all. So we have discussed till now decimal binary and octal. Now comes the most interesting one that is the hexadecimal number system. Why it is interesting? Because it uses 6th, its number system consists of alphanumeric characters 8 and 8, 9. After 9, it uses the alphabets A, B, C, D, E and up to F. So it consists of total 16 alphanumeric characters to represent a hexadecimal number system. So its base is 16. In other way, as the previous number system, we can break any hexadecimal number to decimal ones. So if we can, if you find a number 2, F, E, such type of number, you should definitely understand that this is a hexadecimal number system and for better precise, we write the base here in this way. So till now, we have discussed about the 4 basic number systems. In the next video, we are going to discuss about the conversion of this number system. That means, how we can convert a decimal to binary or binary to decimal or binary to octal, everything will be discussed in the next video. Thank you.
