I discovered this week that the VINGN Broadband project is offering a free online Digital Literacy Course. The course follows an 8 week curriculum that covers computer basics, Internet usage and usage of core software like spreadsheets and word processors. Now if you read the article I linked above there's no link to the sign up site. You can find the sign up site right here.
Overall I think there's enough information there to get you started understanding all this computer stuff. I did find some of the information to be kind of narrow though. For example, you can do charts on presentation software, word processors and spreadsheets but the system insists that spreadsheets is the only way to go for charts. For a total beginner though, this course is decent.
What did I get? Don't let this discourage you. I only browsed the site for the basic feel and didn't view any of the videos. I passed the three pre-tests in the span of about 10 minutes and finished the Master Exam today in about the same amount of time. My grades are below.
