What is this module about?
“People who are more than casually interested in computers should have at least some idea of what the underlying hardware is like. Otherwise, the programs they write will be pretty weird.”
Prof. , Stanford University
The Art of Computer Programming
1974 ACM Alan M. Turing Award
: UCD : COMP30080 : Computer Systems : 0 : Overview 2
Knuth was awarded the 1974 ACM Turing Award “for his major contributions to the analysis of algorithms, and in particular for his contributions to the ‘art of computer programming’ through his well-known books in a continuous series by this title.”
The New York Times referred to it as “the profession’s defining treatise”

What is this module about?
“Even if you never have to write fast software, even if you never have to write device drivers, even if you never have to design a processor, as a computer scientist,
you should still,
once in your life,
write some assembly code just so that you understand how computers actually work.”

What is this module about?
“As a computer scientist, you should be able to read and understand the hardware specification for a computer.”

Professional behaviour in UCD Computer Science
• You are expected to behave professionally in any environment where you are acting as a member of the student body of the school of Computer science.
• This includes lectures, tutorials, and labs run by the school, and also environments not run by the school but informally connected to school membership (such as social media groups run by students for students in a certain stage, course, or module).
• Professional behaviour means following UCD’s student code of conduct and means
• Not disrupting others’ ability to learn by causing conflict or division, making distracting or upsetting comments, or making any student feel unwelcome in an environment which they attend as a member of the student body
• Enhancingothers’abilitytolearnbybeingsupportiveratherthandiscouraging,by being tolerant of difference, by sharing your insights rather than sharing your solutions, and by maintaining good attendance, communication and timekeeping
• The school will intervene in cases where unprofessional behaviour is affecting other students’ ability to learn.
