An introduction to the basic concepts, nomenclature, and historical perspectives of computers and computing. Uses the Java programming language to introduce the concepts of software development and object-oriented programming.
This course will introduce you to the field of computer science and the fundamentals of computer programming. CS101 is specifically designed for students with no prior programming experience, and touches upon a variety of fundamental topics. This courses uses Java, a high-level, portable, and well-constructed computer programming language developed by Sun Microsystems (now Oracle), to demonstrate those topics.
We begin this course with a brief history of software development, and show how human thought and computer programming are related. We build upon these general concepts to cover object-oriented programming terminology such as objects, classes, inheritance, and polymorphism. During this process, we use Java to show how those fundamentals are implemented in a real programming language. We do this by demonstrating Java's primitive data types, relational operators, control statements, exception handling, and file input/output.
By the end of the course, you will have a strong understanding of the basics of computer science and the Java programming language, and the principles you learn here will be developed further as you progress through the CS discipline.
This course includes the following units:
Upon successful completion of this course, you will be able to:
Throughout this course, you will also see learning outcomes in each unit. You can use those learning outcomes to help organize your studies and gauge your progress.

Your score on the exam will be calculated as soon as you complete it. If you do not pass the exam on your first try, you may take it again as many times as you want, with a 7-day waiting period between each attempt. Once you have successfully passed the final exam you will be awarded a free Course Completion Certificate.
There are also end-of-unit assessments and short quizzes in this course. These are designed to help you study, and do not factor into your final course grade. You can take these as many times as you want to, until you understand the concepts and material covered. You can see all of these assessments by clicking on Quizzes in the course's navigation bar.
This course is eligible for college credit via Saylor Academy's Direct Credit Program. If you want earn college credit, you must take and pass the Direct Credit final exam. That exam will be password protected, and requires a proctor. If you pass the Direct Credit exam, you will receive a Proctor Verified Course Certificate and be eligible to earn an official transcript. For more information about applying for college credit, review the guide to college credit opportunities. Be sure to check the section on proctoring for details like fees and technical requirements.
There is a 14-day waiting period between attempts of the Direct Credit final exam. There is no waiting period between attempts for the not-for-credit exam and the Direct Credit exam. You may only attempt each Direct Credit final exam a maximum of 3 times. Be sure to study in between each attempt!
CS101: Introduction to Computer Science I is a self-paced course, which means that you can decide when you will start and when you will complete the course. There is no instructor or set schedule to follow. We estimate that the "average" student will take 52 hours to complete this course. We recommend that you work through the course at a pace that is comfortable for you and allows you to make regular progress. It's a good idea to also schedule your study time in advance and try as best as you can to stick to that schedule.
Learning new material can be challenging, so we've compiled a few study strategies to help you succeed:
This course is delivered entirely online. You will be required to have access to a computer or web-capable mobile device and have consistent access to the internet to either view or download the necessary course resources and to attempt any auto-graded course assessments and the final exam.
