Welcome to the Department of Computer Science. The Department of Computer Science offers programs of study related to computing, information technology and software design and application. Our programs involve interdepartmental, multi institutional and inter institutional collaboration and have attracted faculty members, undergraduate and graduate students from all over the world. Students may pursue full time or part time study leading to a Certificate in Computer Science or to B. Sc., M. Sc., or Ph. D. degrees. The Department currently offers B. Http, a command bundled into Tcl, is a clientside implementation of the HTTP1. 1 protocol. Documentation edit official reference Commands edit. A frequentlyasked questions, also called a FAQ, covers problems with the TclTk programming on the Windows platform. The GUI Toolkit, Framework Page User interfaces occupy an important part of software development. This page provides a comprehensive reference on toolkits for. A commandline interface or command language interpreter CLI, also known as commandline user interface, console user interface and character user interface CUI. This FAQ gives some background and discussion for frequently encountered problems with the ncurses library, the terminal database and applications. Sc., B. Sc. Honours, B. Sc. Computer ScienceMathematics, B. Sc. Honours Computer ScienceMathematics, B. Sc. in Software System Development degrees in its undergraduate program, and M. Sc. and Ph. D. degrees in its graduate program. It also offers a two year certificate program in computer science, for training or continuing education. The Department operates a program in cooperative University education in the four year degree programs. Following the first two semesters of University courses, students spend alternate four month periods taking courses and working in fully salaried computer science related jobs with participating employers. Such a program may improve the students motivation and performance, and the practical experience gained may aid the student in choosing future areas of interest.
