Course description and aims

The essence of “computation” is quite simple: four basic arithmetic operations, zero test, and iteration. What is executed on computers is a “program” consisting of such very simple operations. Computer Science is a field of science and engineering that investigates various methods for realizing what we want to do as “computation” so that it can be executed on computers. This course introduces key concepts and methods for analyzing tasks and problems from the computational viewpoint. This new view should be a key to not only using of computers but also for understanding things in any other fields of science and engineering.

Student learning outcomes

At the end of this course students are able to:
1) Explain how various objects are encoded as binary strings and processed in computers.
2) Understand how a computation is specified as a program.
3) Explain basic concepts used in programming such as variable, branch, iteration, array, and subroutine.
4) Understand the basic structure of computers as a software system as well as a hardware system.


Digitalization, basis of computation, computer architecture, program, programming, software, operating system

Competencies that will be developed

Specialist skills Intercultural skills Communication skills Critical thinking skills Practical and/or problem-solving skills

Class flow

This class is conducted as a remote class. During the class,
programming exercises will be conducted along with lectures. Homework
and report assignments to confirm understanding will be given in the
class. There are also some quizzes in the class.

Out-of-Class Study Time (Preparation and Review)

To enhance effective learning, students are encouraged to spend approximately 100 minutes preparing for class and another 100 minutes reviewing class content afterwards (including assignments) for each class.
They should do so by referring to textbooks and other course material.
