If you're looking for tutorials and information about computers, programming, and other technology related topics, there are a variety of free tutorials available online, in both video and text format.
Below are some links to some tutorial websites that I would suggest you check out! All of these websites offer great tutorials in terms of both quality and information provided.

Additionally, like said before, you may also want to visit your local library or bookstore, where you may be able to find some books on the programming languages and other technology related topics that you'd like to learn about.
Amazon.com is also a good place to look for books, as they have a great selection of books, as well as other items.

As for how to get started with programming, I would suggest that you just start doing it and practice as often as you can. You could try creating programs, scripts, games, and what not, in order to improve your skills as a programmer.
There are also a variety of websites online, such as CodingBat.com, which enable you to practice coding online, with interactive puzzles and practice problems for free. (However, CodingBat only offers practice examples for Java and Python right now.)

Best of luck and I hope I helped you!
