This is a long thread with lots of good advice and some that's maybe not so good.
For a true, absolute beginner I don't think the internet is a great source. Sure, its free and there's a wealth of great information. The problem is sorting through it and finding the stuff that's really helpful and reliable. If you don't know anything about cooking, you also don't really know how to evaluate the information, recipes, etc. you find on the internet. Remember, anyone can post whatever they like. I'd say fully half the information - recipes, techniques, etc., are not especially great. I'm not saying the internet isn't a good source, only that it isn't the best primary source.
The same holds true of cooking shows. TV chefs need to be original and creative, and they're all showman. If not, their shows wouldn't last very long. In terms of learning basic techniques and recipes, they are a useful source but, again, not the best primary source.
Learning from experienced cooks, such as family or friends, is great but not always possible. Besides, even great cooks aren't always great teachers and unless you spend a great deal of time cooking with them, you're only going to learn how to make a fairly limited range of food.
Professional cooking classes are probably the best way to learn, but impractical for most of us.
So, what does that leave? Cookbooks! Not mere recipe collections or celebrity chef cookbooks. Start with good, basic general purpose cookbooks. Several have been mentioned - Betty Crocker, Joy of Cooking, Fannie Farmer, Mark Bittman (How To Cook Everything), and others.
Any of these will do as a start. My strong recommendation is the regular Betty Crocker Cookbook (9th or 10th edition). Everything is clearly explained, with good photos and illustrations, and the recipes are all field-tested and work! You can't do better for a first cookbook and you'll find it to remain a favorite throughout your cooking career. Buy as many other cookbooks as you want and can afford, but buy this one first.
One other important piece of advice, particularly when you're first learning. The first time you make anything, follow the recipe EXACTLY with absolutely no changes or substitutions! Evaluate the result and make notes of anything you think might improve it the next time you make it. Before you know it, you'll have your own personalized "signature" recipes made to your individual taste and earning kudos from friends and family.
