CS 5010 - Programming Design ParadigmIntroduces modern program design paradigms. Starts with functional program design, introducing thenotion of a design recipe. The latter consists of two parts: a task organization (ranging from thedescription of data to the creation of a test suite) and a data-oriented approach to the organization ofprograms (ranging from atomic data to self-referential data definitions and functions as data). The coursethen progresses to object-oriented design, explaining how it generalizes and contrasts with functionaldesign. In addition to studying program design, students also have an opportunity to practice pair-programming and public code review techniques, as found in industry today.CS 5600. Computer Systems. 4 Hours.Studies the structure, components, design, implementation, and internal operation of computersystems, focusing mainly on the operating system level.
