COMP47550 How Computers Work

Academic Year 2019/2020

In order to teach Computer Science at second level teachers require an in-depth understanding of how computers work. In the modern world of Cloud Computing this extends beyond the software and hardware in a laptop, to cover networks, servers and virtualisation.

The course will give a general overview of the basic elements and functional components of computing systems. The material to be covered divides into three parts, foundations of computing at the CPU level, network computing and the Web and scalability and cloud computing. The introduction to the foundation of computing and the CPU will cover Boolean algebra, the operation of a CPU and memory and storage. The section on networking and the Web will introduce the key concepts in network computing and Web services. The final section will cover large scale computing and the concepts underlying cloud computing.
