What is it really? Is it something to help the visually impaired see it better or is the captioning for the hearing impaired? How do you know it is available for the website you are visiting?

It is not for the hearing or visually impaired necessarily.. Let's say there is a broken link on the website.. The website should have an 'alt' attribute to every element. This way whenever you move your mouse over the broken link you will get a caption of what the picture was supposed to be. Now you can get an idea of what the website is about even though the pictured links may be broken.
In the case that the image is not broken, the 'alt' attritibute could be transformed into a voice message for people who are visually impaired.. This would require a plug-in on the other end which would take in the data from the 'alt' attribute and read it aloud.
Also you must be able to view your web page in several different browsers and at several different resolutions. To see if it works try viewing the web page, with internet explorer, mozilla firefox, as well as Opera.. You should also view the web page with a resolution of 800 x 600. If the page is designed correctly, nobody using resolution of 800 x 600 should have to scroll to the right to view the entire page..

Accessibility is a broad topic. It has at least two aspects, (1) accessibility for people with disabilities (at a minimum, the site should allow the user to incresase/decrease print size or at least should not prevent the browser from doing so), and (2) accessibility for alternative clients (mobile devices, WebTV and other set-top boxes, etc.) Accessibility for speech-based browsers can be thought of as either or both of the above, since a speech-based browser is an alternative client used by people with disabilities...

Accessibility is more than anything about COMMON SENSE and GOOD DESIGN: not putting tiny red text on a green background, not making important text as an image.
How do you know if it's on a website you're visiting, well as the old saying goes: if you've done somethin right you shouldn't notice anything's been done at all.
