Component 4: Introduction to Information and Computer Science Unit 10: Future of Computing Lecture 1 This material was developed by Oregon Health & Science University, funded by the Department of Health and Human Services, Office of the National Coordinator for Health Information Technology under Award Number IU24OC

Topics In This Unit Topic I: Trends in Computing Topic II: User Interfaces Topic III: Cloud Computing Topic IV: Social Implications Topic V: Ubiquitous Computing Component 4/Unit 10-1 Health IT Workforce Curriculum Version 2.0/Fall

Topic I: Trends in Computing We can speculate, but we cannot know! Past predictions Changes in ownership Changes in physical size Changes in system memory Changes in system storage Changes in system connectivity Component 4/Unit 10-1 Health IT Workforce Curriculum Version 2.0/Fall

Past predictions “I have traveled the length and breadth of this country and talked with the best people, and I can assure you that data processing is a fad that won’t last out the year.” Prentice-Hall editor of business books, 1957 "There is no reason anyone would want a computer in their home.” Ken Olson, president, chairman and founder of Digital Equipment Corp., 1977 Component 4/Unit 10-1 Health IT Workforce Curriculum Version 2.0/Fall

Changes in ownership Governments in the 1940s Businesses in the 1950s and 1960s Personal computers in 1970s Component 4/Unit 10-1 Health IT Workforce Curriculum Version 2.0/Fall

Changes in physical size Component 4/Unit 10-1 Health IT Workforce Curriculum Version 2.0/Fall

Changes in physical size Component 4/Unit 10-1 Health IT Workforce Curriculum Version 2.0/Fall

Changes in system memory 1 KB for early home systems 2 or 4 GB common for today’s home systems Demonstrates Moore’s “law”: trend showing that the number of components that can be placed on a circuit doubles every two years Observation by Gordon Moore, Intel co-founder, in 1965 Likely to continue through at least 2015 Component 4/Unit 10-1 Health IT Workforce Curriculum Version 2.0/Fall

Changes in system storage Component 4/Unit 10-1 Health IT Workforce Curriculum Version 2.0/Fall

Changes in system connectivity Early computers were stand-alone systems Connected by telephone lines in 1970s and 1980s Internet for personal use through dial-up connections in 1990s –Slow speed – 56 Kbps typical –Still available today Wireless hotspots and WiMAX Component 4/Unit 10-1 Health IT Workforce Curriculum Version 2.0/Fall
