Computer Science Course Descriptions for Fall of 1998

CMPSCI 102: Computers and Society (R2)

Professor: Spinelli

There are three principal components to this course: 1) what computers are, 2) how they are used in society, and 3) how their use affects society. In the first part we explore the origin of computers and the historical, economic, and scientific forces that brought them into existence. We also study the essential hardware components that make up a computer and we learn the basic software methods of programming using the JavaScript language. In the second part, usage of computers by business in the office and in factory automation, by the professions such as medicine, and by artists and scientists is covered; special attention is given to the advent of the Information Super Highway, how to use it and how it can benefit individual users. Finally the economic and socio-political impact that computers are having on society and on the individual are discussed; these issues range from questions of privacy to the impact of robots in the factory, to the use of computers in political action. The primary aim of the course is to impart sufficient computer literacy to enable the student to 1) write simple, but non-trivial programs, 2) make use of and benefit from available computer facilities, and 3) understand why computers have become such a powerful forcein the modern society. Pre-registration not available to majors and pre-majors. 3 credits.

CMPSCI 105: Computer Literacy (R2)

Professor: Verts

Microcomputers are now used widely not only in academia but in all areas of modern life. For this reason it's important that all students understand how computers work and how computers can be used as a problem-solving tool. The focus of this course is on computer applications. The course stresses the ways in which computers can help you solve problems efficiently and effectively. The course provides a broad introduction to hardware and software aspects of microcomputers. Then four application areas are discussed: word processing, spreadsheets, databases and telecommunications (access to the Internet). The course uses the university's microcomputer labs, and weekly 90 minute lab sessions are an integral part of the course. Students who are more interested in computer programming should take CMPSCI 121 or 187. Prerequisites: reasonable high school math skills. Typing ability is also an important asset for the course. Previous computer experience is not expected. Pre-registration is not available to majors and pre-majors. 3 credits.

CMPSCI 287: Programming Language Paradigms

Professor: Popplestone

Lecture, discussion, programming projects, lab. Programming Language Paradigms provide a basic philosophy to support the construction of reliable large-scale systems. This course discusses four such paradigms. In the -functional paradigm- software is constructed in such a way as to minimize the use of side-effects, thereby simplifying the conceptual structure of programs and making them easier to analyze and understand. The -logic paradigm- supports the development of software in which the concept of -relation- (for example a relation between people) is more important than the concept of function. In the -imperative paradigm- we are concerned with principled ways in which software that is state-dependent can be constructed. Finally, in the -object-oriented- paradigm we are concerned with combining data with code to create "objects" which exhibit behavior. Prerequisite: CMPSCI 187. Corequisites: CMPSCI 250 and MATH 132. 4 credits.

The operating system provides a well-known, convenient, and efficient interface between user programs and the bare hardware of the computer on which they run. The operating system is responsible for allowing resources (e.g., disks, networks, and processors) to be shared, providing common services needed by many different programs (e.g., file service, the ability to start or stop processes, and access to the printer), and protecting individual programs from one another. The course will start with a brief historical perspective of the evolution of operating systems over the last fifty years, and then cover the major components of most operating systems. This discussion will cover the tradeoffs that can be made between performance and functionality during the design and implementation of an operating system. Particular emphasis will be given to three major OS subsystems: process management (processes, threads, CPU scheduling, synchronization, and deadlock), memory management (segmentation, paging, swapping), file systems, and operating system support for distributed systems.

CMPSCI 791D: Seminar - System Support for Next Generation Applications

Professor: Shenoy

The current euphoria over the World Wide Web does not do full justice to the potential of the Internet; with the manifold increase in CPU processing power and network bandwidth, it is inevitable that the future Internet will support distributed applications of great complexity. Concurrently, these technological advances have also led to a proliferation of multimedia applications that access heterogeneous data such as audio, video, images, animation sequences, text, etc. This seminar course will investigate the impact of these two trends on the design of future operating systems and networks. The first half of this course will investigate system support for distributed multimedia applications, and will include topics such as predictable allocation of processor, I/O and network bandwidth, and storage and retrieval of heterogeneous data. The second half of the course will investigate how these applications can be deployed over the Internet by providing seamless access to computational and data resources over wide area networks. Topics such as metacomputing, distributed caching on the Internet, and scalable services will be covered. A collection of papers describing the state-of-the art in the field will be made available to students. Students will be required to present papers, participate in class discussions and complete a project on a relevant topic of interest. This course assumes familiarity with graduate courses in operating systems and computer networks.
