CMSC 104 o Assumes NO programming experience o Does NOT count towards your CS major o Prepares you for CMSC 201 CMSC 201 o Assumes some programming experience o First CMSC course for CS majors o Also required for IFSM majors o MUCH more challenging

3 CMSC 104, Version 1/023 What Will We Cover? 1. General computer hardware and software concepts 2. Basic computer use 3. Problem solving 4. Basic computer programming in the C programming language

Your password will be rejected if it is a commonly used word or name. DO NOT GIVE YOUR PASSWORD TO ANYONE!

12 CMSC 104, Version 1/0212 Computer Science at UMBC CSEE Administrative Offices o ITE 325 CSEE Student Services Office (Advising) o ITE 203 - 206 CSHC (Computer Science Help Center) o ITE 201E Linux Users Group (LUG) o http://lug.umbc.edu

13 CMSC 104, Version 1/0213 OIT Labs The Office of Information Technology is responsible for all lab computers. On Web at: www.umbc.edu/oit Labs with PCs: o ECS 021, ECS104, ECS122, ECS122A, ECS333 Labs may be on reserve, so plan ahead! Print Dispatch -- ECS 019 (? cents/page) Hours of Operations –OIT will post outside of labs

14 CMSC 104, Version 1/0214 Consultants vs. Tutors OIT labs are staffed by consultants using software (pine, Netscape, etc.) some text editors (emacs) operating system commands (Linux) cleaning floppy disks (viruses) communicating with UMBC computers (TeraTerm)

15 CMSC 104, Version 1/0215 Consultants vs. Tutors (con’t) CSHC is staffed by student tutors Help with homework and projects emacs and Linux questions ITE 201E – Not open during the summer!!

16 CMSC 104, Version 1/0216 Hardware and Software Needs Do I need my own computer? o No, but it is more convenient for you. If I have my own computer, can I use it? o Sure, but you will use it mostly to log in to your GL account or for word processing. Do I need a C Compiler? o No, and you probably shouldn’t buy one. All programming should be done in your GL account.

17 CMSC 104, Version 1/0217 Using Your Own Computer: SSH TeraTerm is a software communications program Must have an Internet Service Provider (ISP) Two sources for TeraTerm software: o OIT CD o Web: http://www.umbc.edu/oit/ Click on the link for software downloads Consult OIT for help
