is it possible to take photos with a blurred background and a clear subject of focus with a normal digital camera (without using any editing tools)? if so, how do i go about it?
Assuming you mean a compact/point&shoot camera with "normal", yes, it is possible. It is more difficult however than higher-end cameras for several reasons:
1) Most compact cameras have small sensors. The focal length of a "normal" lens scales accordingly, i.e. the focal length is very short. Lenses with short focal lengths tend to depict everything sharp, which works against blurring the background. (The same effect works great for "focus-free" cameras, like handphone cameras and many webcams.)
2) Some compact cameras may have lenses with a relatively small maximum aperture. This also works against blurring out-of-focus areas.
3) Some compact cameras may not allow you to control the aperture setting of the lens (everything is automatic), so you're at the mercy of the camera.
The most effective way to achieve the blurred background despite such limitations is probably to photograph close-ups/macros against a far away background (cliche example: flower against landscape).
For fast moving objects, you can also blur the background (albeit in a different way) by panning during the exposure.
