Am I in the right class?

CMSC 104o Assumes NO programming experienceo Does NOT count towards your CS majoro Prepares you for CMSC 201

CMSC 201o Assumes some programming experienceo First CMSC course for CS majorso Also required for IFSM majorso More challenging


What Will We Cover?

• General computer hardware and software concepts

• Basic computer use

• Problem solving

• Basic computer programming in the C programming language


General Hardware and Software Concepts

• Introduction to computer architecture

• Data representation and memory usage

• Introduction to operating systems

• UNIX/Linux, Windows 95,98,NT,2000


Basic Computer Use

• Basic use of

• an operating system (Linux)• e-mail (pine)• a text editor (pico/xemacs)• the Internet (Netscape and/or Internet Explorer)


Problem Solving

• Problem solving and algorithm development

• general vs. specific solution to a problem • use of top-down design• use of pseudocode• algorithm (code) reuse


Basic Computer Programming in the C Programming Language

• Compiling, linking, and executing a computer program

• Testing a computer program

• C programming language basics


Syllabus

On the Web

“Lecture Schedule” and Grades are also posted on the Web

Refer to the Web throughout the semester


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


Changing your Linux password

Login by entering your id and password given on the sheet

At the Linux prompt type:passwd <Return>

You will be prompted for your new password; type it in and press <Return>

You will be asked to type the new password again


Changing your Linux password (continued)

You will be given a message that the password has been changed

OR you will be given a message that rejects your new password

Passwords should be at least 5 characters long, should be something you will remember.

Your password will be rejected if it is a commonly used word or name


Computer Science at UMBC

OIT Labs

The Office of Information Technology is responsible for all the lab computers

Labs:o ECS 021 -- PCs, MACs, SGI Workstationso ECS 005 -- SGI Workstationso ECS 104 -- PCso ECS 104A -- SGI Workstationso ECS 122A -- PCso ECS 333 -- PCso ECS 336 -- MACs

Labs may be on reserve so plan ahead !


OIT Labs (Cont'd)

Print Dispatch -- ECS 019 (~cents / page)

Hours of Operationso Beginning of Semester,

� Monday – Friday 8:00 am – 10 pm� Saturday 8:00 am – 10 pm� Sunday 12:00 noon – 10 pm

o During Semester,� Sunday 12 noon – Friday 12 midnight (24 hrs)� Saturday 8:00 am - 12:00 midnight.


Consultants vs Tutors

OIT Labs are staffed by consultantso using software (pine, xrn, netscape, etc.)o some text editors (emacs, pico)o operating system commands (Unix/Linux)o Formatting / Cleaning floppy diskso communicating with UMBC computers

CSHC is staffed by tutorso Help with homework and projectso emacs and Unix / Linux questionso ITE 208-E -- Hours to be announced


Logging on from Home

High speed line1: 410 - 719 - 1094 High speed line2: 301 - 322 - 6199

o 56. k bps. Settings for both lines

o No parity, 8 data bits, 1 stop bit On your computer, you must have

o Communications software (Free CD rom from UMBC Computer Services ECS 020)

o A modem


telnet

Connect to your Internet Service Provider (ISP)

Windows 95/NT/98/2000o click: Starto click: Runo Type: telnet linux1.gl.umbc.edu

Login with your UMBC login-

name & password.


Hardware & 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 using it mostly to login to

your GL account or for word processing Do I need a C Compiler?

o No, and if you buy one, you may be wasting your $$$. All programming should be done in your GL account.
