Different Number Systems: Understanding the Details of Digital Representation

Number systems form a fundamental foundation in computing and information technology. These systems are used to represent numerical values ​​in specific ways, allowing computers and digital systems to understand and manipulate information. Here we will explore some of the different number systems and their importance in the context of computing.

1. Decimal System:

Representation: Based on numbers from 0 to 9.

Constant value: The total value increases by 10 as we move from one number to the next.

In this system, each digit represents a place in the number space, and the number is expressed when these digits are combined together.

2. Binary System:

Representation: Based on the numbers 0 and 1.

Constant value: The total value increases by 2 when moving between numbers.

It is used in computers where each value is represented by storage units known as bits, where zero and one represent two different states.

3. Octal System:

Representation: Based on numbers from 0 to 7.

Constant value: The total value increases by 8 when moving between numbers.

Although its use is not as common as that of binary and decimal, it does appear in some software applications.

4. Hexadecimal System:

Representation: Based on the numbers 0 to 9 and the letters A to F (where A represents 10 and F represents 15).

Constant value: The total value increases by 16 when moving between numbers.

This system is used in programming and to represent the color of pixels in images, as it provides a concise representation of binary values.

5. Radix System:

Representation: Depends on any number of digits and is determined by the base (the base is a fixed number that determines the amount of digits available).

Constant value: The total value increases by an amount determined by the rule.

The numerical system is a general system that includes the previous systems, and is used to represent numbers in the context of computing.

The importance of understanding number systems:

Understanding number systems is vital for programmers and computer scientists. It allows them to interact with and manipulate data effectively. For example, in programming, it is important to understand how numbers are represented in memory and how they can be converted from one system to another.
