Binary, Hexadecimal, and Octal for Computer Science Basics

If you want to understand the foundational logic of computing or pursue programming, you must first grasp how computers store and manipulate numbers internally. This course demystifies the different number systems used in digital electronics. By the end of this course, you will be fluent in the core number systems—binary, octal, and hexadecimal—and possess the practical skills to perform rapid manual conversions and calculations, providing a critical foundation for further study in computer architecture and programming. What you'll learn: * Learn the structure and positional value of base-N number systems, including decimal, binary, octal, and hexadecimal. * Master efficient techniques for converting numbers between any base, focusing on shortcuts for binary, octal, and hexadecimal inter-conversion. * Practice performing fundamental arithmetic operations—addition, subtraction, and multiplication—directly within binary and other non-decimal bases. * Understand how negative numbers are represented in binary using essential methods like Two's Complement. * Apply the concepts of base systems to interpret data representation, memory addressing, and basic bitwise operations in programming contexts. The material starts with core definitions and terminology, progresses through structured conversion methodologies, and culminates in practical exercises on arithmetic and data representation concepts. This course is designed for absolute beginners with no prior experience in computer science or programming fundamentals. All concepts are introduced from the ground up.
