Course Description

This course introduces the different number systems commonly discussed and studied in different computer and information technology allied courses - the binary, octal, decimal and hexadecimal number systems and how the conversion process from one number system to another take place.

The materials in this course are presented in video with audio format. Additional learning materials in other formats may also be included in select sub-sections of the course.

The course may be completed in a week's time to a maximum of two weeks on the average by spending one to two hours a day of viewing/learning the video course. For those with slower pacing, the course may be completed in four weeks time. Advance learners may finish the course in one a day and the gifted ones will complete the course right after viewing the whole video course in one sitting including the Course Assessment.

The course is structured by modules, presenting one topic at a time. It begins with an introductory concept and gradually elevates to the core topic discussion. In the core topic discussion, the underlying concepts and principles are presented first, followed by examples and reinforced with exercises, all in the same video. The degree of difficulty of examples and exercises are also presented gradually. The course wraps up with an assessment that contains 10 complex problems with answer keys presented but on a separate video.

This course provides a very sound and strong foundation for anyone attempting to pursue any computer or technical allied (vocational or degree course) as this video course could help implicitly enhance a student's ability to assimilate logic, reasoning, programming skills, vivid mind's view of computer memory mapping, computer memory management and design, cache operation, input/output hardware device interfacing and more, provided they acquired the thorough familiarity with the hexadecimal number system as presented in this course.

What are the requirements?

  • The course is presented in English and uses Romanized character in presenting text contents. Learners of this course must have a functional English listening and reading skills to appreciate the learning intended. It is also ideal that course taker is familiar with the decimal number system and familiarity with it’s notation – the conventional and expanded notation.

What am I going to get from this course?

  • Increase student's mathematical, analytical and logical skills through the number conversion skills
  • Identify binary, octal and hexadecimal number systems in addition to the decimal number system
  • Convert one number system to any other number system -- decimal to binary, octal and hexadecimal and vice-versa
  • Increase and/or identify a student's potential and success in aspiring/pursuing a technical allied course

Who is the target audience?

  • This course is intended for learners of all computer allied degree, diploma and certificate courses and other Information and Technology technical allied course takers too. Life-long learners are also very much welcome to take the course. The course may also be appreciated by any curious mind. To fully appreciate this course, it is best that the course taker has fully understood the basic mathematics principle in numerical notation, as this video course reviewed a topic in one of the earlier mathematics - the conventional and expanded notation which were taught in elementary mathematics.

Section 1: Course Coverage

This video presents the course's outline, what will be discussed and how the course will wrap up.

Section 2: Introduction

This topic presents a brief glance on the Decimal Number System and how the positional values are called. It also briefly presented the numerals used in the Binary, Octal and Hexadecimal Number System.

Section 3: Number Notations, Positional Values & Counting Series

In brief, this video laid out the difference between two conventions of writing numbers - the Conventional or normal form of writing numbers and the Expanded form which was introduced in gradeschool and plays an important tool in learning the core discussion of this course.


This section presents a brief review of positional or placement values and in learning magnitude values as we have learned them in the decimal number system. Power or exponents will be among the expressions that will be encountered in this section of the course. Positional values of both the integers, also known as whole numbers, and the fractional part, also known as decimal part are also covered in this module.
