digital cameras

Zooms have been around a Lot longer than digital cameras, but it wasn't until the mid '70's that computers were used to help design them, making them more affordable and efficient (smaller)
Yes, SLR's (Single Lens Reflex) cameras have the ability to change lenses from the body to adapt to different photo situations. The benefit is that all functions relating to the photo are functions of the lens. You control the aperture (the amount of light passing through the lens), focus, and zoom from the lens, the only function native to the camera is shutter speed. On automatic SLR's the camera body does all of the light calculations and transmits the information to the lens for you.
Optical zoom cameras are used to take a shot in which a far-away object appears both prominently and clearly. Essentially you need a decent zoom lens to obtain this ability, and a good camera with a widely-adjustable lens offers this feature.
The short focal length of a camera lens is so that the image the lens forms is small and can be focused on a piece of light-sensitive film.
Optical Zoom- - - - -Nothing shorter than a 300mm lens, and a 500mm lens might be a good idea.
There are two possibilities; The focus - a motor moves the lens elements in conjunction with a sensor to get a sharp image. The zoom - operating the zoom controls, moves an optical group which gives the photographer the desired angle of view.
A zoom lens is a lens of a camera which contains a mechanical assembly of inner lenses, which allow the focal length of the camera to be rapidly altered.
With the zoom of the lens, I could capture distant objects with my camera.
It depends on the lens one has on it at the time. The lens is interchangeable.
24-105MM Zoom Lens is the best for me.
When you go on an Alaskan cruise, take a camera with a zoom lens. You might not be able to get close enough to some of the mountains to take good pictures, but with a zoom lens, you can get great shots of the snow caps.

It means the zoom power, i.e. how much magnification is possible at the long end of the zoom.
For basic photography you would do well with a basic zoom lens. Just a short zoom lens should handle most photographs for a casual photographer.
That depends on the lens you put on the camera.
The 12x on a zoom camera means the digital cropping of an image which is enlarged in size. This creates the illusion of a zoom effect. So basically the lens can crop forward to get a closer look of something 12x.

Canon EF-S 17-55 f2.8 is a nice normal zoom lens.
