Computer science is a study of computers, technology, and their implementation as software and application. People interested in learning about technology and solving computational problems opt for computer science courses, degrees, and certifications.

In today’s modern world, people who know about computer science can develop different ways to use technology. Computer science is an interesting concept if you have great problem solving, computational thinking, and analysis skills.

What are the best courses in computer science?

People often think computer science is all about programming. Well, that’s not the complete truth, the computer science field consists of many subfields. The subfields include artificial intelligence, databases, algorithms and data structures, networks, security, graphics, and programming languages.

The choice of subfield solely depends on your interests. Computer science is a wide concept, which needs to be studied with interest and effort. Many online learning platforms offer basic and advanced level courses for computer science.

We have divided the courses into two sections-

  1. Special computer science courses
  2. Subfield specific courses

If you are already inclined towards the specific field, then you can take up those courses. However, if you are not clear about subfields but interested in technology, then taking up introductory or high-curriculum computer science courses would be a wise decision.

Special Computer Science Courses

Computer Science Courses

The special part of the course list consists of courses that either give an introduction or explain computer science concepts and history in brief. There are certification and specialization courses as well in the list. If you wish to take up a computer science graduate program, then the courses listed below can help you get you a glimpse into the graduation program.

Note: All the courses from Udemy have lifetime free access with mobile and TV compatibility.

Pro tip: If you are interested in enrolling in a course from Udemy, you may want to wait for one of their promotions before purchasing. Udemy frequently offers promotional discounts that can range anywhere between 10% to 90%. Please do note that not all courses have this promotion.
