This course presents an overview of computer science (CS) with an emphasis on problem-solving and computational thinking through 'coding': computer programming for beginners. Other topics include: organization of hardware, software, and how information is structured on contemporary computing devices. This course is pre-requisite to several introductory core courses in the CS Major. The course is also required for the CS minor. MATH 12500 or higher is strongly recommended as a co-req for intended Majors.

Each week we have:

This is a HYBRID course which means that, in place of a second weekly meeting, you are responsible for independently reading the weekly Lab found in the "Handouts" column in the Course Outline below.
Starting on September 13, there are programming assignments due at 6pm every day. Programming Assignments are directly related to Labs and Lectures. The schedule contains the specific deadlines.
Lecture notes will also be posted weekly in the "Handouts" column in Course Outline below.
