The Department of Computer Science has access to a variety of computers for both research and instructional use. The main computers for instructional use are PCs and Macs. Upper level courses also use a variety of other computers, including Unix workstations. Most instructional facilities are operated by Information Technology Services (ITS). Students should review ITS bulletins or visit their website for complete information on services, hours of operation, and conditions of access. The Department of Computer Science also has its own network of workstations, primarily used for research purposes. The department operates research laboratories for experimental computer science research in programming languages, distributed computing, computer vision, multimedia and natural language processing, mostly located at 715/719 Broadway. Selected undergraduates assist in work on these areas at this facility.
