Introduction to Computing (Udemy.com)

Enter a world where programming languages are real people, and computing concepts have a physical reality. Data Streams will sweep you away on an adventure to stop the Hacker from destroying the Internet, in a town like no other. A town where email worms can swallow you whole and computer viruses stalk the streets looking for their next victim.

Here you will meet Python, who's really easy to get to know, and Java, who knows everybody. Together, they'll help you learn the skills you need.

Although not everyone is friendly, the Database Administrator doesn't care how much SQL you learn, there are other, dangerous, forces at work here. So take care.

Along the way, a whole array of characters will help you learn the Computer Science you need to prevail, like the Servers who have escaped from their racks; Pop, and Denise. And the designer, Gooey, who'll teach you the basics of Web design and HTML. Then there's Doc who, unsuccessfully, tries to get anyone to read a manual.

But, the place holds a dark secret and, just maybe, our guides, Peta and Zeta Byte may be able to save not only the Internet but also put right a larger injustice, that lives at the very heart of the town.

All of the software you need is free, you just need a computer that you can download, install and run the software.

Good luck and I hope you enjoy it.
