Computer science Specializations and courses teach software engineering and design, algorithmic thinking, human-computer interaction, programming languages, and the history of computing. Courses in this broad field will help you think abstractly, approach problems methodically, and develop sound solutions.
Computers are an essential part of our internet-enabled lives today, but what does it mean to study computer science? Computer science, often referred to as CS, is a broad field encompassing the study of computer systems, computational thinking and theory, and the design of software programs that harness the power of this hardware to process data.

Computer science lends itself particularly well to online learning, for obvious reasons - after all, where better to learn about computing than on your computer? Self-motivated learners can choose from a wide range of great courses. Many CS professionals started off learning from personal programming projects, classes, and bootcamps.
A career in computer science can take you pretty much anywhere! All sorts of companies need web developers, software engineers, mobile application developers, and other experienced programmers, giving you opportunities to use your CS skills to advance your career in an incredibly wide range of industries. Most tech-related companies also have a Chief Technical Officer (CTO), enabling your CS career to take you all the way to the C-suite.
Just as there are a plethora of different computer science careers you can pursue, learners looking for good online computer science courses may feel overloaded by all the choices out there! As discussed above, introductory courses in individual programming languages are a good place to start, and you can find plenty of options in popular languages like html and css, Javascript, object-oriented programming in Java, and Angular.js, Python programming, Scala, Linux, and Ruby On Rail.
Yes! Online computer science education isn't limited to individual courses anymore. Online learning platforms now offer a full range of accredited degrees, from Bachelor of Science (BS) in Computer Science to graduate-level degrees like Masters of Computer Science (MCS) and Master of Science in computing.
Those studying computer science may end up taking a similarly broad range of career pathways. Many CS majors focus on building skills in software programming, coding, and web development, all of which are highly sought after by a wide variety of companies. However, others may focus on more specialized topics such as algorithmic problem solving, machine learning and artificial intelligence, cybersecurity, and even robotics!
Before starting to learn computer science, you would want to gain a fundamental understanding of how computers work, how software is created, and how networks can deliver data and information. Having some work experience in software development, project management and software engineering would be beneficial, as well as learning programming languages like Java, SQL, Python, and JavaScript. These are not necessary, however, to get started in learning about computer science. Being able to learn new areas around computers can help you to gather the knowledge needed for learning computer science.
The kind of people who are best suited for work that involves computer science are often computer science graduates who have started their careers doing software development, network infrastructure, or LAN/WAN work. The field of computer science covers a wide array of jobs for analytical people who are hardwired to code, think in-process, and manage projects using software tools. People who succeed in this field are often those who stay current with modern work practices.
Some of the newest related topics that are of interest to those who are learning computer science may include algorithms, operating systems, computational complexity, computer design, information theory, programming languages, systems and architecture, software development and testing, and web applications and databases. Learning more about any of these topics can open you up to new understanding of computer science principles.
The types of places that are hiring people with a background in computer science could be just about any company today. Technology has entrenched itself into so many industries that becoming knowledgeable about computer science can bring you into a new technology career in a rather short time. Companies want highly skilled software engineers, database administrators, and network architects to handle computer science needs. Moving your career in this direction may increase your chances to help these companies grow with their digital transformation.
Alongside mini and full degrees programs, you can audit many Coursera and edX courses for free, which can be a great way to explore new interests or quickly brush up on some skills.To access the full programs, including graded homework, unlimited course access, and a verified certificate of completion, you'll have to pay a one-time fee on edX or a monthly fee on Coursera until you finish the course.
In this introductory computer science course, students learn "how to think algorithmically and solve programming problems efficiently" using concepts like abstraction, algorithms, data structures, encapsulation, resource management, security, software engineering, and web development.
This course covers the main principles of computer vision: Digital signal processing, neuroscience, and artificial intelligence. Topics include color, light, and image formation; early, mid- and high-level vision; and mathematics essential for computer vision.
Computer Science is the study of computer technology, including both software and hardware. It is an exciting and diverse field that can teach students skills that are in demand across almost every industry in our tech-driven world. This broad subject encompasses multiple specializations and sub-disciplines in theory, analytics, hardware and software systems, data science, and more.
The course is extensive, which is why we have listed it at the top of our list. Anyone looking into the best free online course in computer science should check this option out first. No prior programming experience is necessary, and the course can be taken at your own pace.
This online computer science course assumes no prior knowledge, and there are no prerequisites. Students who are already versed in most of the above concepts will likely find the course too rudimentary; however, for the absolute beginner, it is ideal. A certificate of verification can be purchased for $149 but is not a requirement as the course can be taken in its entirety for free.
Learning to program is the fundamental first step in computer science, and this course presented by Princeton University covers the subject in-depth with over 40 hours of learning. Unlike some of the other introductory courses on our list that use Python, this one uses Java, although the main goal is to teach students programming as a whole.
You will learn essential programming elements like loops, arrays, conditionals, variables, and I/O. The free online computer science course then moves on to concepts like modular programming, recursion, and code reuse before it introduces object-oriented programming.
Taught by computer science professor Wade Fagen-Ulmschneider, the free computer science course online is intended for students who have already taken an introductory course in a programming language like Python and who can write a program.
This excellent intermediate course on Udemy will give students a basic introduction to theoretical computer science. Entirely free, it is a two-month-long program taught by industry pros. Rich in content and superbly easy-to-follow, the course features interactive quizzes, an online student support community, and plenty of practical exercises. There are seven modules that can be taken at your own pace.
Before taking this free online computer science course, students should have a basic understanding of programming and algorithms, but no prior experience with theoretical computer science is necessary. 2ff7e9595c
