The principals are the same. If you use an old lens on a new body or vice versa you will lose the autofocus function. Also many digital cameras have smaller sensors (known as cropped). So a 50mm lens on your SLR will be about a 78mm on your DSLR because the image is being projected onto a smaller space. This may be a benefit if you use long lenses for sport / wildlife but not if you generally use fish eye! You can now buy full frame DSLRs that are equivalent to 35mm so the lens would not alter. Also lenses are constantly evolving with better glass to prevent chromic abberation, etc and with built in image stabilisation, etc.
My understanding is that an SD card is an SD card, no matter what the use is. The difference is what data is stored on it. (eg. Photos or music)
Mostly trigger voltage is different. Older film flashes used higher voltages, which if used with newer digital cameras can fry the sensitive circuitry in it. A good practice to follow would be to buy flashes made by the manufacturer of your camera, for your camera. Always remember to check the compatibility of your flash with your camera model.
Conventional/traditional photography is the use of film to capture images in a camera. The film then must be developed, resulting in negatives (negative images) of the images. These negatives are then enlarged using special equipment and paper and then printed and developed chemicals. Digital cameras capture images using sensors on a memory card, which are then transferred to a computer for printing on specialized printers. The benefits of traditional darkroom photography is the amazing quality of the photographs. Only in recent years has digital photography even began to compare to the quality of traditional film, but it is increasing in both quality and popularity. In the near future it is projected to be equal to and even surpass traditional photography. The benefits of digital photography are the ease of use and convenience. Images can be viewed and deleted instantly, instead of shooting through multiple rolls without knowing if you have a successful image.
A optical zoom use the lenses to focus in on a subject, pretty much the same way binoculars work. Digital zoom magnifies the subject by enlarging in in the pic thru a digital process, this is not a true type of zoom.
A digital camera is a portable camera that runs on batteries and usually has a slot for a memory card to save pictures and videos to. They generally have better image quality, presently ranging from around 8-12 megapixels on average. This is what you usually see people carrying around for taking pictures. A webcam is a small camera that connects to a computer [or is built into a laptop] and is generally used for video chats online. They have lower quality than a digital camera.
There is a difference between the Nikon camera and the Sony camera. The Nikon camera has more features and it is also wireless. The Sony camera is digital.
The main difference between a digital camera and a regular camera is that a digital camera does not need film in order to work. The Canon A430 is inexpensive and a good starter digital camera. It's priced around $170 but will last you a long time.
You need to expand your question a bit more. Are you asking about the differences between digital vs. film? That question is being answered in other threads. OR.... Are you asking if you can convert a film camera to digital? The answer to that is yes, sometimes. Personally I would not recommend it, just go buy a digital camera.
Its a camera that uses film. Like a digital camera has a memory card. a conventional camera uses the film which you then have to get printed before you can see the image.
SLR digital cameras are professional grade cameras which have settings which may be manipulated to produce outstanding photos that otherwise could not be achieved with a regular digital camera
you can preview pics on a built in display and download pics to a computer
Digital just takes a small clip of the image and enlarges it while optical is just like if you stepped in closer to whatever you are photographing.
SLR stands for Single Lens Reflex - if it doesnt say digital then its probably a film camera (35mm).

Traditional Photography records light from a camera on to film, digital records the light on to a light sensitive digital CCD that transferrs the image into data and records it as a digital file.
A digital video camera is definitely your best bet for posting videos to the web. Since it is completely digital it is much easier to transfer data.
No. You cannot economically convert a film camera to a digital camera. The digital system is very different and fitting it to an existing film camera is more expensive than buying a new digital camera. Some of the more expensive professional cameras can change between film and digital backs replacing the film transport with digital technology. The replacement backing includes all the electronics and controls typical of a digital camera of that caliber.
