Learning how to program is among the most in-demand and valued skills there is. The foundational knowledge is called Computer Science, and it naturally lends itself to being taught online. In fact, the nature of the industry and the cost of making learning tools have allowed learning computer science to become an activity once can do for free! Free programming or computer science courses are easy to find yet some of the ones you find may not be worth your time. We’ve put together a list of computer science courses from well-respected institutions such as Yale, MIT, Stanford, and Harvard. Hopefully, this free resources will help you advance your knowledge of programming towards a career in technology, software developing, artificial intelligence or web based services. Computer science is the study of the theory, experimentation, and engineering that form the basis for the design and use of computers. It is the scientific and practical approach to computation and its applications and the systematic study of the feasibility, structure, expression, and mechanization of the methodical procedures (or algorithms) that underlie the acquisition, representation, processing, storage, communication of, and access to information. An alternate, more succinct definition of computer science is the study of automating algorithmic processes that scale. A computer scientist specializes in the theory of computation and the design of computational systems
