Introduction

What is Computer Science?

Computer Science is the study of processes that interact with data and that can be represented as data in the form of programs. It enables the use of algorithms to manipulate, store, and communicate digital information.

Administrative information

Course Syllabus is available here

Communication:

  • via slack: workspace name: bitl-cs1-2019
  • via email: use instructor's email address for personal communication
  • office hours: by appt.
