### What is Octal?

The octal number system is a base-8 numbering system that uses digits from 0 to 7 to represent numerical values. It is commonly used in computer programming and digital systems, particularly in contexts where binary numbers are prevalent.

Octal numbers offer a compact representation of binary values, as each octal digit corresponds to a group of three binary digits (bits). They are often used in conjunction with binary numbers for addressing, permissions, and other low-level operations in computing.

While octal numbers are not as widely used as hexadecimal or decimal numbers in modern computing, they still hold significance in certain applications, especially those involving hardware-level operations and legacy systems.

### What is Decimal?

The decimal number system, also known as the base-10 numbering system, is the most widely used numeral system worldwide. It uses ten distinct symbols, namely 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9, to represent numerical values.

Decimal numbers are fundamental to everyday arithmetic and mathematics, serving as the primary means of expressing quantities in everyday life. They are used in various fields, including finance, science, engineering, and commerce, for counting, measuring, and calculations.

In computing, decimal numbers are often used for high-level programming, user input, and output, as they are more intuitive for human understanding. However, they are less efficient than binary or hexadecimal numbers for low-level operations and memory storage in digital systems.
