These two distinct credentials can kickstart or bolster an IT career. But which one is right for you?
The free online courses with certificates below may provide numerous benefits.
Learners can find courses for the easiest programming language to learn and the most difficult. They can specialize in a particular tech field, like cybersecurity, or answer the basic question, is computer science hard?
Other reasons you might explore these classes include:
The value certificates hold depend on the employer and the situation. Some employers recognize that these credentials complement a college degree and offer specialized training opportunities. (In fact, colleges also offer undergraduate and graduate certificates, such as web development certificates.)
Other employers may not care about certificates but may value the skills you’ve learned while earning them.
But don’t confuse certifications vs. certificates. Information technology certifications are awarded by professional organizations and vendors that meet industry standards. You may see certifications in specific technologies or with specific vendors listed as job requirements.
In the following alphabetical list, we highlight the platforms offering the most useful online computer science courses.
Some offer access to online classes from postsecondary institutions, and others feature third-party training programs and credentials.
Note that for most platforms, while completing a class may be free, obtaining the associated certificate costs a fee. Also, note that while most award certficates, some (such as Microsoft Learn) may also offer certifications.
