Digital logic and circuits, micro-programming, and assembler language concepts, characteristics of operating systems, file systems, and resource allocation; Unix and its variants.

The first part of this paper will cover the basics of computer architecture, including data representation, digital logic and devices, combinational and sequential circuits, structure of a computer, memory systems, data input and output, microprogramming and assembly language concepts. The second part will cover the concepts and fundamental principles of operating systems, including processes, interprocess communication, process scheduling, memory management, virtual memory, file systems, I/O management and resource allocation. These concepts will be illustrated with examples from the Linux operating system.

Teaching Arrangements
There are two 1-hour lectures and two 2-hour tutorials per week.
