Two basic data processing concepts are described: data elements (consisting of bits, bytes, fields, records, and files) and binary characters (standards, hex value, and extended character sets--Greek letters, superscripts, and subscripts). Use of machine-readable data in the OCLC-MARC database is noted. (EJS)

Defines and describes the components and functions that constitute a microcomputer--bits, bytes, address register, cycle time, data path, and bus. Characteristics of 8-, 16-, and 32-bit machines are explained in detail, and microprocessor evolution, architecture, and implementation are discussed. Application characteristics or types for each bit…

Discusses the advantages of parallel processor computers in terms of expandibility, cost, performance and reliability, and suggests that such computers be used in library automation systems as a cost effective approach to planning for the growth of information services and computer applications.
