Requirements

The course teaches how to convert numbers in one base (binary, octal, decimal & hexadecimal) to another base (binary, octal, decimal & hexadecimal).

You will learn what the number system is, and why it is so important in IT, Electronics, and other fields of science. This is fundamental knowledge that every Computer Science student and programmer must possess.

You will learn how the data is represented inside the computer, including images, sound, and text.

I explain different concepts using examples because people learn the most by doing and examples, not only by theory.

Conversions are shown step by step using animation in PowerPoint in a way that helps you to grasp the core ideas easily.

Course duration is only 2 hours, so consequently, students can cover conversions in one week if given sufficient time for the course.

Remember that it is very essential to perform some exercises and try to solve some conversions on your own in order to be proficient and comfortable with the topic.
