Well there are cameras that do everything for you (shutter speed, apeture, focus, film speed - even on digital - and so on)
There are also cameras that, as well as being automatic, will let you override these settings and set your own film speed, apeture, and shutter speed.
IF you are considering doing photograph for a living it is VERY important you understand film speeds, shutter speeds and apeture.
For example changing the apeture has a big impact on the depth of field. If you are taking a close up of someones face you want a narrow depth of field with the background out of focus.
If you are taking a landscape shot you want a wide depth of field where the forground and background are in focus.
Unluess you have a camera that allows you to set these options you will never learn about the basics of photography.
Eventually you need to buy a Digital SLR with a qood quality lens, and the ability to change lenses, a camera like this:

But for now maybe a decent compact digital would be a starting point, but one that allows you to change the settings like I indicated above.
