An Introduction To Computer Science

This book is suitable for use in a university-level first course in computing (CS1), as well as the increasingly popular course known as CS0. It is difficult for many students to master basic concepts in computer science and programming. A large portion of the confusion can be blamed on the complexity of the tools and materials that are traditionally used to teach CS1 and CS2. This textbook was written with a single overarching goal: to present the core concepts of computer science as simply as possible without being simplistic.

Discusses most ideas behind a computer in a simple and straightforward manner. The book is also useful to computer enthusiasts who wish to gain fundamental knowledge of computers.

An Active Learning Approach to Teaching the Main Ideas in Computing Explorations in Computing: An Introduction to Computer Science and Python Programming teaches computer science students how to use programming skills to explore fundamental concepts and computational approaches to solving problems. Tbook gives beginning students an introduction to

Classroom-tested by tens of thousands of students, this new edition of the bestselling intro to programming book is for anyone who wants to understand computer science. Learn about design, algorithms, testing, and debugging. Discover the fundamentals of programming with Python 3.6--a language that's used in millions of devices. Write programs to solve real-world problems, and come away with everything you need to produce quality code. This edition has been updated to use the new language features in Python 3.6.

This textbook covers the content of a general introductory lecture in computer science held at a German University. The basic stuff for most special courses - circuit technology, programming, operating system, networking, security, and more - is presented along with some further background information not necessarily covered by other lectures, but helping to understand relationships and reasons why certain techniques are done in just that way. The learning process is supported by numerous exercises. 2nd edition with minor changes and clarifications. A forum is now available on http://www.gilbertbrands.de/smf/ . Though the primary language of this site is German, feel free to post your comments in English.Dieses Lehrbuch deckt den Inhalt einer allgemeinen Einführungsveranstaltung in die Informatik ab. Die grundlegenden Dinge für die meisten spezielle Kurse - Schaltungstechnik, Programmierung, Betriebssysteme, Netzwerke, Sicherheit und vieles mehr - werden zusammen mit einigen weiteren Hintergrundinformationen, die nicht unbedingt von anderen Vorlesungen abgedeckt werden, sondern dazu beitragen sollen, Beziehungen und Hintergründe, warum bestimmte Techniken in einer bestimmten Weise ausgeführt sind, verständlich dargestellt. Der Lernprozess wird durch zahlreiche Übungen unterstützt.Zweite Auflage mit kleinen Änderungen. Ein Forum ist unter http://www.gilbertbrands.de/smf/ für Fragen, Kommentare und Anregungen verfügbar.

Introduction to Computer Science introduces students to the fundamentals of computer science by connecting the dots between applications they use every day and the underlying technologies that power them. Throughout, students learn valuable technical skills including how to write simple JavaScript programs, format a webpage with HTML and CSS code, reduce the size of a file, and more. Opening chapters of the text provide students with historical background, describe the numbering systems that computers operate with, and explain how computers store and convert data such as images and music. Later chapters explore the anatomy of computer hardware such as CPUs and memory, how computers communicate over networks, and the programming languages that allow us to solve problems using computation. The book concludes with chapters dedicated to security and privacy, the structure and function of operating systems, and the world of e-commerce. Accessible in approach, Introduction to Computer Science is designed to help non-computer science majors learn how technology and computers power the world around them. The text is well suited for introductory courses in computer science.
