Looking at your previous questions I can only assume you are just starting out, and probably only have a small budget.
What you need to look for in a camera - the sort which will allow you to take a photograph as opposed to a snap - is the ability for you to take control of main functions: Aperture, Shutter, White Balance, ISO and metering.
These are the technical elements you will need to master alongside composition and an understanding of light.
To do this I would recommend an entry level camera such as:
Olympus E410, 420, 500, 510, 520.
Canon 350D,400D,450D,1000D
There are many other cameras but the above I have experience of as a 'new' photograher, and I own a Canon 450D and three olympus cameras (420, 510 and 520) - My children are beginning photography too.
Most of the above come as kits with a decent wide/telphoto lens.
Hope this helps.
