Office Systems and Technology Chapter 1: Terminology and Basic Concepts of Information Processing
Information Processing • Processed data that is timely, meaningful, and useful • Requires computer hardware, software, and communication channels/networks • Six-step process includes: data origination, input, processing, storage, output, and distribution
1 Data Origination 2 Data Input 3 Processing 4 Storage 5 Data Input 6 Distribution The Information Processing Cycle
Raw data are organized for processing during the data origination phase Data input can be entered in a batch or online Information is data that has been processed into a usable format Data can be stored for future use using a secondary device Data output communicates the processed information to others Information (reports) can be distributed to users in hard or soft copy formats The Information Processing Cycle
Information Processing Operations • Basic operations include recording, duplicating, verifying, classifying, sorting, merging, calculating, storing and retrieving, summarizing, and report writing • Advantages of using a computer relate to speed, accuracy, consistency, and reliability • Operation modes are designed to facilitate specific business needs
System Architecture • Clarify the needs of the user for the information system analyst • Be sure computer-based information system is integrated within the organization • Information architecture should include all functional areas and business processes (internally and externally)
Information Technology Infrastructure • Computer hardware • Software • Storage • Data management • Networks Includes all of the technical resources shared within the organization
Early Computers • Charles Babbage, “Father of Computers” (1833) • Mark I, Antanasoff-Berry Computer, ENIAC, EDVAC (1940s) • The first business computer, the UNIVAC (1951–1958)
A New Generation of Computers • Joint effort between business and science (1959–1964) • Logic element used transistors • Internal and secondary storage • Operating system and high level languages • First integrated circuit (1958) • First minicomputer (1965)
Another Computing Era • Computers become more affordable (1965-1970) • Integrated circuit allowed primary memory to store more information • Internal and external storage material improves • Advancements in operating systems and high-level languages • Ted Hoff of Intel, Corp. introduced the microprocessor (1971)
Microcomputer Evolution • MITS Altair, the first microcomputer (1975) • Intel 8080 with 256 bytes of RAM • Kit available for $500 or assembled for $2500 (does not include keyboard or monitor) • Apple computers are introduced (1976) • Apple II became popular followed by the Apple Macintosh • IBM PC, clones, and MS-DOS are introduced (1981) • More than 830,000 machines sold in one year
ARPANET to WWW • ARPANET began as a government project • 20 sites in 1971 • 200 sites in 1981 • Evolved into the Internet in 1990 • The World Wide Web (WWW) • Internet language and Internet addresses created by team lead by Tim Berners-Lee in 1989 • By 1993, the Internet grew over 350,000 percent
Computing in the 21st Century • VLSICs allow computers to be smaller, faster, more reliable, and less expensive • Internal storage is mainly semiconductor • Secondary storage utilizes magnetic disks, optical discs, and portable USB flash drives to store data in a small physical space • Systems software is expanded • Internet and WWW have moved business and society into a cyber e-world
