Wirth, Niklaus – Scientific American, 1984
Built-in data structures are the registers and memory words where binary values are stored; hard-wired algorithms are the fixed rules, embodied in electronic logic circuits, by which stored data are interpreted as instructions to be executed. Various topics related to these two basic elements of every computer program are discussed. (JN)

Winograd, Terry – Scientific American, 1984
Discusses four types of computer programs that can manipulate linguistic symbols with great facility. These programs deal with: (1) machine translation; (2) word processing; (3) question answering; and (4) adjuncts to electronic mail known as coordination systems. Also considers the future of computer software dealing with language. (JN)

van Dam, Andries – Scientific American, 1984
Interactive computer graphics is fast becoming the standard medium of communication between computers and all kinds of users. Reasons for this trend, the technology of interactive graphics displays, software considerations, applications (including classroom and laboratory applications), and future developments are discussed. (JN)

Tesler, Lawrence G. – Scientific American, 1984
Discusses the nature of programing languages, considering the features of BASIC, LOGO, PASCAL, COBOL, FORTH, APL, and LISP. Also discusses machine/assembly codes, the operation of a compiler, and trends in the evolution of programing languages (including interest in notational systems called object-oriented languages). (JN)

Denning, Peter J.; Brown, Robert L. – Scientific American, 1984
A computer operating system spans multiple layers of complexity, from commands entered at a keyboard to the details of electronic switching. In addition, the system is organized as a hierarchy of abstractions. Various parts of such a system and system dynamics (using the Unix operating system as an example) are described. (JN)

Lesk, Michael – Scientific American, 1984
Discusses software developed to organize and retrieve electronically stored data, examining structure of the databases in which information is stored and the physical structure of the storage medium. Hierarchical and relational databases, unordered files, B-trees, and storage/software for specific purposes (such as weather, stock market, and…

Spector, Alfred Z. – Scientific American, 1984
Computer software for process control has the primary function of communicating with and governing physical devices. The structure of such software, process-control systems, multitask systems, message passing, problems of deadlock, distributed computer systems, and protection against failure in process-control systems are among the areas examined.…

Searle, John R. – Scientific American, 1990
Discusses whether machines can think in the same sense that humans think. Provides four conclusions based on axioms of differences between computer programs and human minds. Compares claims of strong and weak artificial intelligence. (YP)
