Episode 13: Notational Systems: Binary, Hexadecimal, Decimal, and Octal
18 Aug 2025
This episode explains the core notational systems used in computing, including binary, hexadecimal, decimal, and octal. We describe how each system works, why it is used, and the relationships between them. Understanding these systems is critical for interpreting system settings, memory addresses, and color values, as well as for reading and writing low-level data representations.We also cover conversion techniques and examples, such as translating binary to hexadecimal for IP addressing or understanding octal in file permissions. These skills are important both for exam success and for interpreting technical documentation or performing configuration tasks in IT roles. Produced by BareMetalCyber.com, where you’ll find more cyber prepcasts, books, and information to strengthen your certification path.
