  1. CS110 - Lecture01 • CS110: Survey of Computing • Introduction (why take CS110?) • Organization of course: syllabus.pdf • Using the Tablets • Student Surveys • Ranking of Success Factors

  2. CS major • Want to learn to use computer • Computational/Honors requirement • Dad made me • Love computers/fun • Useful information/skills

  3. Motivation • Working Conditions • Job Outlook • Earnings 25

  4. Chapter Goals • Describe the layers of a computer system • Describe the concept of abstraction and its relationship to computing • Distinguish between systems programs and applications programs • Distinguish between computing as a tool and computing as a discipline 25

  5. Computing Systems Computing systems are dynamic! What is the difference between hardwareand software? 2

  6. Hardware vs. Software HardwareThe physical elements of a computing system (printer, circuit boards, wires, keyboard…) SoftwareThe programs that provide the instructions for a computer to execute 3
