Number Systems
Course Highlights

This online engineering PDH course provides an introduction to the various types of number systems used by computers and in computer programs.

 

While the decimal number system is convenient to humans, it is not practical for use by computers.  Computers use electrical signals which assume two (2) states, on and off for example, to represent numbers.  Computers are also limited to the number of digits that they can use to represent numbers.  As such, methods must be used to convert numbers from a human readable form to a form that computers can use.

 

This 4 PDH online course is intended for design professionals, as well as, those who require a basic knowledge to design and review computer hardware and software designs.

Learning Objectives

This PE continuing education course is intended to provide you with the following specific knowledge and skills:

  • Recognizing different types of number systems as they relate to computers
  • Identifying and defining unit, number, base/radix, positional notation, and most and least significant digits as they relate to decimal, binary, octal, and hexadecimal number systems
  • Adding and subtracting in binary, octal, and hexadecimal number systems
  • Converting values from decimal, binary, octal, hexadecimal, and binary-coded decimal number systems to each other and back to the other systems
  • Adding in binary coded decimal
