Recordings of Class Meetings

You will find links to the recordings of class meetings here.

Use of Storage Space on the CS LAN

All of you will have an account on the Computer Science Department network.

With this account you get a home directory.

There is a limit on the total size of the files in your home directory.

So you should not store there anything you do not need for your classwork.

Homework 2

I have posted homework 2 here.

It is due this coming Sunday at 11:59 PM.

From now on, each class will have a Class Quiz.

The Class Quiz is ungraded.

It is designed to help you remember the material covered in class.

Here is how it works.

The first graded quiz will be given on Tuesday next week.

The questions from the graded quiz are taken from the ungraded quizzes of the previous week.

Unless I tell you otherwise, you should expect a graded quiz each week.

The quiz will be available on Gradescope on Tuesday.

Class Page for IT 116

You may find it useful to look at my materials for IT 116.

You will find these materials here http://96.126.105.215/umb_classes_html/it116_html/class_page_it116.html .

I have included this link on the class page for the course.

Go to the index for the Class Notes and search for a topic.

Do Not Post Anything From this Class Online

There are many web site that claim to "help" students learn new material.

As far as I am concerned sites like Chegg and CourseHero get their money by helping students cheat on their assignments.

Posting ANYTHING on such sites is a violation of your Oath of Honesty and will be reported to the Provost's Office.

This includes quiz and exam questions as well as homework assignments and Class Exercises.
