1,DSLR (Digital Single Lens Reflex) cameras - These cameras have a moving mechanical element inside that helps the light coming through the lens reach the optical viewfinder that is on the back of these cameras. Fast autofocus, short shutter lag, and way larger sensor are those elements that are usually typical of them.
2, Image sensor - It is a small part behind the mirror mechanism inside the camera. As the mirror flips up, light coming through the camera lens reaches the image sensor. This is actually the most important part of cameras; it determines mainly the depth of field and the overall noise level.
3, Depth of field (DOF) - DOF determines how much the subject can be separated from the background. It depends on two main factors that are as follows: focal length and aperture. The following image is a great example of shallow DOF:
4, Aperture - A camera lens is very much similar to human eye. There is an iris inside the camera (lens diaphragm) that regulates how much light can enter the lens. The larger the aperture is, the more light enters the lens making the depth of field shallower. Larger aperture can also result in less contrasty images. Stopping down the lens itself can increases contrast and sharpness, but significantly reduces the DOF, which may look like less professional.
5, Focal length - It is marked on lenses as "XX mm." The length decides the field of view. The smaller the focal length is, the more field of view is available. The longer it is, the more the subject is separated from the background. If you use a wide angle lens, it is unlikely that you'll be able to reach shallow DOF. While these wide angle lenses are suitable for landscape photography, longer lenses are used for portrait, sport, and astro photography.
6, Night photography - Taking great photos in low light conditions requires a fairly great technical background. If you're considering doing night photography without a tripod, the best you can do is get a stunning low light performer, most preferably a portrait lens that has a big aperture (f1.4, f1.8). It enables you to take handheld photos without blurring the images.
Wide angle lenses can also be used for this sort of photography. All you need is a stable tripod and patience. Taking a photo at night with a lens that has a smaller aperture can be a pain in the neck; however, it's really not that difficult. The shutter speed should be as long as possible and the lens should be stopped down in order to get bright, sharp images.

7, Bokeh - It originates from Japanese and it means intentional blurring. Bokeh is the out-of-focus are on a photo. Numerous photographers include bokeh lights in photos, making them look like more professional.
Here's an example of what bokeh light means:
