Digital Number System in Computer System

Updated: Aug 18

In the world of computing and digital systems, mathematics in the form of digits is used as a component of the main language that symbolizes certain values. For those of you who are learning about computer systems and want to know more about this, then you must be familiar with the digital number system.

In this system, each number used and also its position in the number position represents a different code. This rule is actually quite complex and quite difficult to understand for those of you who are not familiar or do not know at all about computer systems. But you can see various brief explanations about this digital number system here.

What is Number System in Computer?

If you have ever seen films about programmers or people who program digital systems, then you must have seen that there are many scenes where on the screen will be displayed many different arrangements of numbers.

Something like this is the description of the digital number system. Although not exactly the same as the picture in the film, this depiction of the use of numbers on the screen is true.

In various computer systems and digital systems, this well-known programming language mostly uses numbers as the main language. This "language" in the form of an arrangement of numbers is internationally accepted as a symbol for certain codes.

In short, the digital number system is a way of writing codes or symbols used to describe a number. The number systems commonly used in the digital system are the decimal, binary, octal and hexadecimal number systems.

Engineers and scientists use the binary number system to make it easy for computers to understand. This system is used by various digital devices, such as watches, digital TV set-top boxes, calculators, burglar alarms, cell phones and computers.

What are The Type of Number System in Digital?

As mentioned earlier, in the digital number system there are 4 groups or types of numbers used. The first is decimal numbers, binary numbers, octal numbers, and also hexadecimal numbers. Each of these types of numbers is actually distinguished according to its number base.

For example, this binary number uses base 2 numbers, namely 0 and also 1 . While the octal number itself, after the name, is based on the number 8.

What Are The 4 Types of Number System?

We will now discuss more about each of these types of numbers. Here are the brief explanation:

1. The Decimal

The first is the decimal number. Decimal or base 10 number system is one type of number system on a computer whose presence is generally used in daily activities.

This number system uses 10 kinds of symbols which include: 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9. Decimal numbers can be in the form of a decimal integer, or a decimal fraction which can also be in the form of a fraction. number. These numbers represent decimal numbers regardless of their value.

2. The Binary

Another one is the binary number. The computer number system that has a base 2 or known as binary is the basis of the entire computer number system that has a digital base. In the binary number system the user can also convert from binary to a hexadecimal number system or octal number, of course this system is often known as a binary number, bit or binary digit.

3. The Octal

The next one is the octal number. Octal or base 8 computer number systems have a total of 8 symbols used, including 0, 1, 2, 3, 4, 5, 6, and 7. the three-bit binary value from the far right corner (Least Significant Bit or LSB).

4. The Hexadecimal

And last on the digital number system is the hexadecimal number. This hexadecimal number is a digital number with a base of 16 digits and alphabets (0,1,2,3,4,5,6,7,8,9,A,B,C,D,E,F). So different from the previous types that do not use the alphabet, the hexadecimal type itself uses a mixture of letters of the alphabet and numbers to represent a value.

That's some brief explanation about the digital number system that you should know as a beginner in digital computing. Find other information about techs and computers on our website.
