The first part of the Digital Systems stream covers the basic architecture of a computer, information representation and manipulation using logic gates, controlling computers using microcode, language compilation and interpretation, communication with the outside world: input/output devices and techniques.

At the end of this course, students should have an understanding of the key features and components of computer systems, including low level components such as registers and adders and how these can be controlled through the use of microprogramming techniques. They should also have appropriate skill to work with different logic constructs and number systems, and in particular binary. Students should also understand the relationship between applications software, systems software and hardware.
