Introduction to Computer Science and Programming

This introductory course has been designed by Tokyo Tech and it's a great start to learn more about data and to get a basic programming experience. The aim of this course is to introduce students with no prior knowledge to basics and key concepts of computer science.

Context of the course and objectives

The process carried out by a computer is referred to as "computation." A computation can be a simple mathematical process or it can be a complex computer simulation needing a lot of data and resources. By following the lectures and exercises of this course you will get an understanding of algorithms and practical experience by using Ruby programming language.

In order to better understand computation and data, you will first learn how a computer operates. Then you will learn crucial concepts like "arrays," "characters," and "strings," and you will gain more knowledge of functions and subroutines throughout the lectures, before moving on to more difficult topics like encryption and cryptanalysis. In order to gain practical experience and a greater knowledge of the concepts being discussed, learners will practice with activities along the way.  At the start of the course, a thorough description of how to set up the environment to run programmes written in the Ruby programming language will be given.

By the end of this course you will be able to create your own programs for encryption and decryption of English texts. A general summary of recent developments and research trends in the field of computer science is provided as the course comes to a close. This final section discusses the fundamentals of computation as well as its practical uses in contemporary culture, including simulations, data mining, and artificial intelligence (AI).
