Determine how you learn the best. There are various mediums of education available to learn about computers, so it is important to choose a medium that best suits your learning styles. For example, if you are a hands-on learner, you may want to seek an interactive computer class rather than reading an educational book.
Set up a schedule to learn once your medium is chosen. If you are learning by reading a book such as "The Complete Idiot's Guide to Computer Basics, 3rd Edition," make sure you read the entire book within a set time period. Otherwise, you may forget key concepts and theories.
Take a basic computer class at a local college or university if you can afford to. Many of these classes focus on the basic concepts and theories of how a computer functions. They often allow you to complete assignments in class with the assistance of the professor so you gain hands-on experience.
Test yourself. There are free online websites that offer computer knowledge tests, such as through the University of Maine. This is a good way to make sure your skills are developing and can eventually be used for real-world experiences.
