Unit 2: Components of a 
Computer System
This unit describes the components of a computer system in relations to the Von Neumann 
Architecture. It describes the peripheral parts of a computer system and the software that 
makes the hardware components of a computer system operational.
Unit Goals
Upon completion of this unit the learner should be able to: 
• Describe Components of a computer system;
• Distinguish elements of the Von Neumann Architecture;
• Differentiate the types and functions of software systems; and
• Explain the stored-program concept of the Von Neumann Architecture.
