This book introduces the binary, octal and hexadecimal numbering systems used in computer science and computer programming. It introduces how numbers are represented in each of these systems, how to convert between them (and to and from base 10). In this book, among other things, you will * What are number bases (also known as radixes) * What is binary (base 2) * How to convert binary numbers to denary (base 10) * How to convert denary numbers to binary * What is octal (base 8) * How to convert octal numbers to denary * How to convert denary numbers to octal * Why many programmers and computer scientists use octal * How to convert octal numbers to binary * How to convert binary numbers to octal * What is hexadecimal (base 16) * How to convert hexadecimal numbers to denary * How to convert denary numbers to hexadecimal * Why many programmers and computer scientists use hexadecimal * How to convert hexadecimal numbers to binary * How to convert binary numbers to hexadecimal * Is there a reason to prefer octal over hexadecimal or vice-versa?
The book introduces you to denary, binary, octal and hexadecimal notations
It is a 5 star book for beginners. Because it soes not hold back with the simplest explanation possible and detailed examples. The author really wants you to understand these notations and their explanation through and through. It is also short and concise.
If you have decided to enter the world of computers, and looking for the entry point to it , then I would definitely recommend starting with book first and before any other computers/programming book to first understand how computers work.
