  1. Introduction CMSC 104 Spring 2001 Problem Solving and Computer Programming

  2. Am I in the right class? • CMSC 104 • Assumes NO programming experience • Does NOT count towards your CS major • Prepares you for CMSC 201 • CMSC 201 • Assumes some programming experience • First CMSC course for CS majors • More challenging

  3. Getting a GL Account at UMBC • You MUST have a GL account • Go to room ECS 020 (in the basement) and ask at the desk, OR • Using the Internet, go to: accounts.umbc.edu (NO www.) • Your account can be used in approximately 1/2 hour

  6. Computer Science at UMBC • CSEE Administrative Offices • ECS 210 • CSEE Student Services Office • ECS 201 • CSCM (Sea Scum) • Computer Science Council of Majors • CSHC (Computer Science Help Center) • ECS 332 In the Mechanical Engr Dept.

  7. OIT Labs • The Office of Information Technology is responsible or all the computers • Labs: • ECS 021 -- PCs, MACs • ECS 005 -- SGI Workstations • ECS 104 -- PCs (but not 104A) • ECS 122A -- PCs • Print Dispatch -- ECS 019 (8 cents/page)

  8. OIT Labs (Cont'd) • Open, but sometimes reserved • ECS 333 -- PCs • ECS 336 -- MACs • Hours of Operations • Before 2/18, • Monday – Saturday 8:00am – midnight • Sunday 12:00 noon – midnight • 2/18 – end of semester, • Essentially 24 hours a day/ 7 days per week

All programming should be done in your GL account.

  12. Course Overview • Introduction to Computer Organization and Architecture • Data Representation and Memory Usage • Introduction to Operating Systems • Problem Solving and Algorithm Development • Introduction to Software Engineering Using Top-Down Design • Compiling, Linking and Execution • C Programming • Reuse Based on Algorithm Selection and Design Techniques
