What are the characteristics of filmless cameras?

A filmless camera is now a digital camera. Instead of film, it uses a memory card (SD card) to save images. Its advantage is that it can delete unnecessary photos at any time, unlike a broken film camera that has to be thrown away, and there is a limit on the number of negatives. Depending on the size of the memory card, a digital camera can store hundreds to thousands of photos. Another advantage of a digital camera is that it can be used as a video camera and can shoot videos. All the functions of other film cameras are basically available in digital cameras.
