A Level Computer System Architecture Syllabus


Objective of the course is to familiarize students about hardware design including logic design, basic structure and behavior of the various functional modules of the computer and how they interact to provide the processing needs of the user. This subject mainly focuses on the computer hardware and system software. It aims to describe the following aspects—

  • Building blocks of the computer
  • Computer Design
  • Assembly Language Programming
